[Tutorial] How to burn 1Mhz & 8Mhz bootloader using Arduino IDE 1.6.5-r5

[ahmedadelhosni]

@rsachoc Maybe I need to rephrase the sentence
I meant that any crystal value will work. I didn't have 16Mhz, but I had the values 10Mhz and 20 Mhz. So I tested with 10 Mhz and I bypassed the error and didn't come again. I wanted to know further whether the crystal value is important or not. So I got another chip with preloaded arduino bootloader, and tested with 20Mhz. Also I succeeded. Thus I assume that you can use any value for this step .

I am also using Uno clone and this is the only thing I did regarding this issue. I didn't even add capacitors to the crystal. Just put any value and test.

[rsachoc]

@ahmedadelhosni thanks! I'm going to grab a 10mhz and 16mhz to test later this evening. Just to confirm from what you've said, I don't need the capacitors? I know in the youtube vid there were capacitors used?

[ahmedadelhosni]

@rsachoc yes. I didn't also have caps and it worked

[ahmedadelhosni]

@rsachoc ofcourse if you have 16Mhz and capacitors like the reference video, that would be great. but if you were in a hurry and lazy to buy some, so just do it like so.
Edit: 16* Mhz not 10 Mhz

[rsachoc]

@ahmedadelhosni I have some capacitors, but no crystals, so I'm picking a 10mhz and 16mhz up later today. I'll try with just the capacitors first and see how I go.

Thanks!

[ahmedadelhosni]

@rsachoc edit: sorry I meant 16. Like the normal arduino board

Did I burn the bootloader successfully? The video indicates it should take longer, this literally took less than a second?

[ahmedadelhosni]

@rsachoc I haven't burned a bootloader since I have did this topic, but I do remember that it took like 2 seconds. It was really fast.
You can try flashing the code to verify that it works well.

[rsachoc]

@ahmedadelhosni good idea, I hadn't thought of that. I'm going to have to build a slim temp node first, as my current chip is soldered to the board with no bootloader.

[LastSamurai]

Hey guys, I have been building my own sensor nodes that should consume as little power as needed, so I burned a 1MHz bootloader with lower BOD settings which I found in the "slime 2AA battery node" thread (I guess this here is the same one).

I had some problem with the node afterwards, which I fixed by setting the baudrate of the mysensors library to 9600. It seems like that is needed (too), beside settings the upload speeds. Can you guys confirm that? If so I would suggest adding that to the (great) manual!

[rsachoc]

@LastSamurai I've been advised that setting the baud rate in myconfig.h is the correct way to get things working when uploading sketches to the slim node. Don't think it matters when burining the bootloader though.

[ahmedadelhosni]

@LastSamurai I have faced this problem a couple of times but I don't remember how do I solve it. I just keep trying different solution. But I have to say thay I am using development branch and I don't redefine the baud rate if I don't wan't the serial debug.

[siod]

thx for the tutorial. I perfomred every step you described, but I get errors when trying to upload a sketch:

And I also get this error message:

I tried to upload the 1MHz version

edit:

some more info form verbose mode output:

edit2:

Another problem: I could burn the bootloader on to one of my ATMega328 MCU´s but I needed to use a 16MHz Crystal when uploading for the first time. Now I can just burn and burn the bootloader again. Here ist the output:

But it is the only MCU that works, all the other give the "Yikes" error, also when 16MHz Crystal is connected:

Any explanation?

- bootloader burning problem solved by rebuilding the wiring.

- for some reason I could upload the sketch now, don´t ask me why. In the end I just reuploaded again and again...I hope I will be able to upload sketches to the next MCU´s as well

Sorry for asking so many questions, but after spending hours and hours of setting up a raspberry pi with openhab, MQTT Broker and MQTT Gateway I am so close to finishing my first standalone sensor and it´s not going any further, I could cry

[drock1985]

Hi,

Maybe someone in here can help me. I can't seem to compile any sketches on my Arduino IDE and keep getting errors spit at me. I can burn the bootloader with no problem but not any sketches. Any advice/ideas please? I'm running out of things to try.

Hello,

Could someone help me and give info what I'm doing wrong or have an idea whats happening.

I use this tutorial and burn 1Mhz on Atmega328. After that I'm trying to upload sketch with FTDI and test Atmega in two ways:

1. When I connect power supply 2xAA batteries (new ones)
2. When I connect power supply 5V from FTDI.

When I trying to upload sketch with 2xAA batteries, Atmega comes unresponsive and I get:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xe3

When I trying to upload sketch with 5V from FTDI - everything ok, example works (blink or ASCII table example).
When sketch is uploaded with 5V and then I try to connect 2xAA bateries - its not working again. When I open serial monitor from arduino IDE I see blank window or few times there was strange character.

I checked few times boards.txt file with fuse setting, and there is set "apm96.bootloader.extended_fuses=0x07" wich means BOD disabled. So it seems should be like that.

I was trying to do all steps with different Atmega328 and also trying same steps when I burn 8Mhz bootloader. Got same result.

Please give me some shots what I could test else here, becose I'm out of ideas. I'm trying to run My Slim 2AA Battery Node.

Thank You! Any help would be very useful.

@jacikaas

From the symptoms you describe, it seems the BOD is still set at the original 4.3V.

There is an Arduino sketch which allows an Arduino do check which fuses are set on another processor:

http://www.gammon.com.au/forum/?id=11633

This will allow you to be certain that the fuse settings on the slim node are correct.

The boards.txt file is just a settings file, so better to check the fuse settings on the processor itself.

Thank You for reply! I got the results:

Programming mode off.

How I understand:
LFuse = 0x62 this one ok
HFuse = 0xDE this one ok too
EFuse = 0xFF this one is not ok and thats why I get struggling, how I understand it should be 0x07
Lock byte = 0xEF this one not ok too, am I right?
Clock calibration = 0xA0 don't know is this one ok or not

So what I should do differently for programming theese fuses?

[GertSanders]

@jacikaas

Actually the fuse setting for EFuse is correct. In the boards.txt file only the least significant 7 bits are set (0x07), instead of all the bits (as in the result of Nic Gammon's sketch or the AVR Fuse Calculator).

So 0xFF is correct.

What else can be wrong ?

Bad connection of the battery ?

[GertSanders]

@jacikaas

What is the upload speed you are using now ? This is defined in the boards.txt file for each board selected.

I found that if I burn the bootloader with 5V FTDI, and then try to upload sketches at 3V (with batteries connected), the internal oscillator runs at a slightly different speed.

When you use higher upload speeds, this small difference can result in too high error rates.

That is why I use 9600 baud to upload sketches for 1MHz mcu's.

For 8MHz mcu's I use 38K4 baud, and for 16Mhz I can use 115K on Arduino Uno's, but I tend to use 56K on my 16Mhz nodes.

Each time I use the approriate bootloader compiled for that clock speed.

[GertSanders]

@jacikaas

Is this the part of the boards file you use ?

[jacikaas]

@GertSanders

Battery connection is good. Battery voltage: 3.25V (when not connected to circuit)
I check again all wiring, measure voltage on circuit and its 3.22-3.23V, check voltage directly on chip pins - its same voltage too.

Still got "not sync" when trying to upload sketch. Interesting that when I have connected battery power and try to upload sketch over FTDI, led conected to D13 blinks and after that I get "not sync".

Upload speed is: apm96.upload.speed=9600

Yes, I use same part in boards.txt file like in screenshot you posted and also like in the given link in tutorial: https://forum.mysensors.org/uploads/files/1443392940975-add-to-boards.txt

If I burn bootloader to Atmega328, with battery powered, shoud it might work?

[GertSanders]

@jacikaas

It's worth a try. Not sure if it will make any difference. But centainly try it.

[GertSanders]

@jacikaas

I think you lock byte should be different in the boards.txt file:

bootloader.unlock_bits=0x3F
bootloader.lock_bits=0x0F

Now you have 0x2F as lock-bits value, and I think this is for a different processor. Most atmega328 based boards have a 0x0F value in the boards.txt file.

So try that too.

[jacikaas]

@GertSanders

No luck with burning bootloader when I powered it with battery. Got swearing from arduino:

avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.

Error while burning bootloader.

Trying to change lock bits to 0x0F in boards.txt file. Burn 1Mhz bootloader. Check it with Atmega_Board_Detector and I could see it has changed to Lock byte = 0xCF. Connect to FTDI(RX,TX,RESET) and connect battery power. Trying to upload sketch and got:

Also I tried to connect 3.3V from Arduino UNO to Atmega328 and upload over FTDI. Sketch uploaded and working (in serial monitor ASCII table).
In this situation I disconnect 3.3V from Arduino UNO. Connect Battery power and in serial monitor with same baud rate 9600 I see empty white window. When I change the baud rates, LED on Atmega328 D13 pin blinking, but still serial monitor empty. Sometimes, randomly, I get character "˙".

[GertSanders]

@jacikaas
No idea what could be wrong now. Not being able to burn the bootloader using battery is strange.
I use a seperate "master" Arduino compatible board as ISP, and I burn the bootloaders when the nodes are powered by the 3V3 from the "master" arduino. After that the FTDI (also giving 3V3) never gave me any grief.
I have no experience using just AVRDUDE directly, I always go via the IDE.

[jacikaas]

@GertSanders

So I will wait when moon phase will change and then try it again

I do a little pause, then try to do all steps from zero very carefully.

[jacikaas]

@GertSanders

Hey, today I start everything from begining. What I do first: I reinstall my Windows and install newest version of Arduino IDE.

Check all wirings. Try to add resistor on bootloader burn breadboard like in this picture.

First I was trying all the same tutorial as described in this topic with 1Mhz, on 3x Atmega328.
Then I try to change the lock bits to 0x0F also on 3x Atmega328.

When I burn bootloader, I do the same, like You, @GertSandees, write before:
I use a seperate "master" Arduino compatible board as ISP, and I burn the bootloaders when the nodes are powered by the 3V3 from the "master" arduino. After that the FTDI (also giving 3V3) never gave me any grief.

In 3 scenarios (when lock bits are 0x2F and later 0x0F) I have:

1. When I connect power from FTDI (3.3V) Everything works fine.
2. When I connect battery power (~3.25V) with ASCII table template I have:

1. When I connect battery power (~2.66V) i got in serial monitor:

AÓÿ

or something like that "ASÿ". Randomly.

I dont know whats happening. Battery powered circuit somehow reacts... I fell a bit frustrated. I don't have an answer what is bad with it...

[GertSanders]

@jacikaas

You will need to make a picture of your setup so we can see how you use the FTDI interface and how you use the processor when only on battery.

I wonder how you are connected when using battery and when using FTDI. Without seeing the two ways of connecting , there is no guessing what is going on.

[jacikaas]

@GertSanders

Hey, here is photos:

1. When powered from FTDI:

3. When powered from battery with 2.66V:
   https://goo.gl/photos/d1UedQWryBoNfTVd6

[GertSanders]

@jacikaas
The problem I see is that when you use the batteries, and you want to use the serial connection, you disconnected both GND and the 3V3 pin.

You should only disconnect the 3v3 pin, and leave the GND pin connected on the board.

[GertSanders]

@jacikaas
So only disconnect the white cable but leave the black one in the breadboard.

[jacikaas]

@GertSanders

Thank You!!! That was very silly failure, which eats a lot of time... But it breaks the ice :)))

Thank You a lot @GertSanders !

[siod]

Hi guys,

I flashed a few sensors already using the 8 MHz and 1MHz bootloaders. I would like to know if I could update my nodes OTA or would I have to modify sth. to make it possible?

[GertSanders]

@siod
For OTA you need to flash the boot loaders that allow this. The standard boot loaders do not have this ability to OTA update.

[flopp]

I am also having problem upload with FTDI, I can upload sketch if I use UNO as ISP.
I read that someone also have problem above but nothing is helping me.
I am using Arduino IDE 1.6.8.
Can it be the version of Arduino IDE?

[dpressle]

@flopp The only way i was able to upload with ftdi is to connect RTS pin to pin 1 via a 0.1 uf cap

[flopp]

@dpressle
OK will try. Cap minus to GND and cap positive to RTS?

EDIT: I am using 1Mhz setup
I change the LOW fuse and Extended but what I can see is that my changes only changes the BOD and internal oscillator.

low_fuses=0x42
extended_fuses=0x06

I noticed that my board have high_fuses=0xde, this setting the 1MHz board also have but not 8MHz. This mean that I dont have any space for Bootloader, can this be my problem?

[flopp]

I tried with above 8MHz setting and then I can upload to ATmega with a FTDI.

I will try to change settings one-by-one until I cant upload and write back here.

[flopp]

With this board.txt config

atmega328bb.name=ATmega328 on a breadboard (8 MHz internal clock)

atmega328bb.upload.tool=arduino:avrdude

I can upload with FTDI. When Arduino IDE change from "Compiling sketch" to "Upload", disconnect DTR and it work.
With my sketch it was using 12,9 uA when sleep
Same result if I change f_cpu to 1000000L

[flopp]

Today I could upload without removing DTR

Ok, but after the new release of mysensors ver 2.0 lib and my wish to update my gw and sensor nodes I would like to add OTA update ability as well for upcoming updates.

• So does a 1 MHz Bootloader with OTA exist that is compatible to the one from above?
• Could OTA easily be added to the above 1MHz Bootloader?
• Should i just use the "ATmega328 internal 8Mhz with MYSBootloader" instead of the above mentioned bootloaders?

[cimba007]

Recently I read a lot about the 0ms, 4.1ms, 65ms start-up time of the low fuses.

I thought adding a small example to prove that the 65ms start-up time is apparently only important during initial powerup.

Used library: https://github.com/rocketscream/Low-Power

Testcode:

#include <LowPower.h>

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
  Serial.begin(19200);
}

// the loop function runs over and over again forever
void loop() {

  LowPower.powerDown(SLEEP_15Ms, ADC_OFF, BOD_OFF);  
  Serial.write(".");
  Serial.flush();
}

First dot:

Second dot:

= 15ms (sleep) + 2ms (serial communication)
~17ms including overhead for sending serial command

I will try out your bootloader and I can only say that it looks promising

[cimba007]

I ran into an rather strange problem.

Mygateway is using esp8266_mqtt_client @ 80Mhz and my node is using the 1mhz bootloader.

If I enable debug logging on the gateway everything is working fine.

Upon disabling debug logging on the gateway and enabling debug lobbing on the node I get this:

TSP:PING:SEND (dest=0)<\n>
TSP:MSG:SEND 11-11-0-0 s=255,c=3,t=24,pt=1,l=1,sg=0,ft=0,st=ok:1<\n>
TSP:CHKUPL:FAIL (hops=255)<\n>
!TSM:UPL:FAIL<\n>

Note that I don't use hardware ack. My assumption is that it takes too long to switch from send mode on the node to receive mode and that the gateway is responding too "fast" for the 1mhz node. Could this be possible?

I even tried out 57600baut serial data rate on the node thanks to this "calibration" sketch for the internal oscillator.

void setup() {
  Serial.begin(57600);
  pinMode(A4,OUTPUT);
  Serial.println(OSCCAL);
}

// Use hterm to repeatatly send the same message unti you cacn read it
void loop() {
  static uint8_t val = 140;
  OSCCAL=val;
  //Serial.println();
  Serial.print("Osccal= ");  
  Serial.println(OSCCAL,DEC);

  delay(500);
  //digitalWrite(A4,HIGH);
  //delay(1);
  //digitalWrite(A4,LOW);
  //delay(100);
  while(Serial.available())
    Serial.write(Serial.read());
  val++;
  if(val > 200)
    val = 140;
}

Just add this

void before()
{
  Serial.begin(MY_BAUD_RATE);
  OSCCAL=150;
}

with 150 is the middle of the OSCCAL values where the serial calibration sketch is working. (its working from osccal 140 to osccal 160)

Yesterday I burn with above settings, I had to use 5v to power the pro mini(I don't know if the pro mini is 5 or 3.3v) I had to power it with 5v otherwise I couldn't burn any new bootloader.

[GertSanders]

@flopp

To use the FTDI connection:

You need a ceramic cap (not polarised).

RTS - CAP - RESET pin of ATMEGA

RESET pin needs a pull up resistor of 10K, connect as follows: VCC - 10K resistor - RESET pin of ATMEGA

[MasMat]

Help!
I semi-followed this thread but also built a shield like this:
http://www.instructables.com/id/Arduino-UNO-as-AtMega328P-Programmer/

For the Uno, the ArduinoISP sketch goes fine. After that, I connect the shield and 328p and upload stuff.
Since my build has 3.3V regulated power (using PCB My Slim 2AA Battery Node..but I can sneak wires to it easily so no need for batteries), I selected 'Board -> Pro Mini' and type '3.3V 8Mhz'. Burn bootloader goes fine, no errors. Upload sketch using programmer (Arduino as ISP) also uploads fine.
When I plug it in (USB FTDI-clone 3.3V selected) and see serial monitor, it remains blank. Nor does the node work when plugged into power.

Anybody else try this? Ideas? The slim node has all caps and resistor connected.

EDIT:
I used the recommended board download from 8Mhz instructions and bingo, it's working...partly. Have to check radio wiring.
Should just follow instructions and not go off on my own......

[MasMat]

Continuing on...I need help getting my Atmega328P-PU to work.

I'm able to burn the bootloader (8MHz on breadboard) and upload sketch ("using programmer"). However when I power the PCB, the sketch doesn't run. I soldered on a LED and uploaded BlinkWithoutDelay, just to verify that it works, but does not. I measured power and all connections. I'm powering with regulated 3.3V.

To make things more weird, I connected FTDI to one node and with that connection it works fine. But when powering from pins, nothing (again using regulated 3.3V.

[electrik]

That sounds more like your power connections are not good. You should check them again.
Or perhaps the capacitor of the ftdi makes the difference, and you should add one in your circuit.
Are the atmegas genuine or can they be fake ones?

[MasMat]

@electrik Everything's 100% chinese
I checked power at all terminals and the atmega-connections, as well as radio hookup etc. I have all the caps on "My Slim Node" (4x 0,1yF and 4,7 yF). I normally get better power thru regulators than with FTDI but I did check that originally.

I built two like this, same type of problem. I have Gert Sanders's "boards" installed. Is there a very basic setup I could try? I'm having trouble figuring out all the options that are available. All I want is Atmega working like a normal 3.3v/8MHz Arduino.

[electrik]

Did you read this?
https://forum.mysensors.org/topic/9388/atmega328p-au-counterfeit/15

[MasMat]

I have now. I always have that nagging feeling...
But after MANY iterations, finally success. At least partly.

BlinkWithoutDelay works AND mysensors sketch as well (will do more testing...).
What made it work, if anyone else struggles with this:

-connect uno (to computer-linux), board:uno, upload ArduinoISP, disconnect
-add shield to uno and atmega328p-pu to shield, connect to computer, board: "8mhz on breadboard", "programmer: "Arduino as ISP", burn bootloader, disconnect
-board: Uno, connect as above, "upload sketch using programmer", disconnect EDIT this last part appears to work but internal clock is all messed up. Bootloader works fine like this.

The magic happened after I changed the board back to Uno after burning bootloader. Why is beyond me, but maybe some arduino-ninja can figure it out.

[bjacobse]

As I recall depending of frequency you need to adjust sketch upload baudrate, Maybe "uno" board have the "correct" baudrate defined for your frequency
https://forum.arduino.cc/index.php?topic=92663.0

[MasMat]

Can someone help me with these questions?
I want the Slim Node to function "like a 3.3/8mhz pro mini" for MySensors home autom applications. So I can upload sketches thru ftdi-pins. Since I also use Pro Minis, I would not want change the mysensors library (serial baud).

1. if I load the bootloader with a 8mhz crystal on the breadboard, does my barebones Slim node need a crystal too?
2. If I set serial.begin in the sketch, does it override the MySensors default? So I could have that for slim node sketches.
3. What kind of nodes would be problematic without crystal use? Repeater?
4. Is it possible to Uno+breadboard just bootload all atmega328p's and then just solder onto SlimNode and use ftdi for uploading sketches (as I would normally to a Pro Mini)? In other words do I have to rethink the whole thing.

EDIT, to help others

1. if the bootloader is not set for crystal, it's not needed.
2. yes
3. ? Repeaters work fine.
4. yes.
   My biggest problem was a capacitor missing between RST and GND when uploading bootloaders. After adding that to my shield, everything works.
   Now I bootload 1Mhz (battery nodes) and 8Mhz (non-bat) once I get them and then program them with the FTDI when I build the nodes.

[mfalkvidd]

@masmat I don't know about the other questions, but for the baud rate you can use

#define MY_BAUD_RATE 9600

(or some other speed that you want to use)
Documentation: https://www.mysensors.org/apidocs/group__SerialDebugGrpPub.html#ga36a01c35b670e1f0797fd63d2ad76ed2

[pihome]

First of all thanks to all who worked on this tutorial and bootloaders. i got fascinated about 8mhz and 1mhz with internal clock after reading this tutorial.

Some might say 1mhz 8 times slower then 8mhz hence need longer awake time to do perform task before it can go back to sleep and consumes more power but what i found: point is not it takes 8 times longer to perform task but it can run it on battery longer and on lower voltage when battery ist at its peak youth.

Anyway i wanted to share my experience and errors i had and the fix i found after googling around and spending hours trying to figure out what is going on.

if you follow instructions as it is then you will end up with second boards.txt file located at C:\Program Files (x86)\Arduino\hardware\breadboard\avr\boards.txt, this file contact info about ATmegaBOOT_168_atmega328_pro_8MHz.hex only. So far so good and it works but for some reason when i try to add 1mhz bootloader to C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt it just wouldn't work, the 1mhz bootloader wouldn't show in in board selection option but if i add info about 1mhz bootloader to "C:\Program Files (x86)\Arduino\hardware\breadboard\avr\boards.txt" then i could see option for "APM Optiboot internal 1MHz noBOD 9600baud" but when i try to burn this bootloader i get all sorts of error on burning bootloader, one of the error: Could not find tool avrdude (sorry didn't copy all error messages)

Then some forums suggest to start clean i.e uninstall Arduino ID and reinstall but simply uninstalling and reinstalling ID doesn't work you need to delete Arduino15 folder from following location(s) and reinstall Arduino ID:
C:\Users(username)\AppData\Local\Arduino15 or C:\Users<username>\AppData\Roaming\Arduino15 or C:\Users<username>\AppData\Local\Arduino15

What i think is best to keep your boards.txt file in one location and modify it and add bootloaders in it and this worked for me. Simply copy your bootloaders to C:\Program Files (x86)\Arduino\hardware\arduino\avr\bootloaders and modify C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt for additional bootloaders.

Dear Sir,
I'm trying to use the 8MHz bootloader, but I kindly ask you in detail where I've to copy the files extracted from the zip file breadboard-1-6-x.zip.

Actually I'm using an Arduino IDE 1.8.10, the sentence that I need some explanation/confirmation is the following one:

"Open your Arduino folder path and move the breadboard folder from the zip archive to the "hardware" folder of your Arduino sketchbook."

is the Arduino sketchbook folder located at the path listed from:

File=>Preferences=>Settings

at the text field with label "Sketchbook location"?

At this path I've no other "hardware" directory, just only a libraries folder, so if this is the right path I've just to simply copy and paste the "breadboard" folder into this one, I'm correct?

Thanks!
Fire

[MasMat]

@FIRE-FOX The answer depends a little on what OS you're using.
In linux I have an Arduino-folder where the program files (not necessarily the sketches) are AND a hardware folder. Also on OSX I have an Arduino-folder (where I have my sketch-directories and libraries and hardware.
Locate the hardware-folder (use whatever search-option your OS has) and you can pretty easily figure out where the breadboard-directory goes.

I wish you luck with the bootloader programming. I went crazy a couple of times but once I got the routine down, it's worth the trouble.

[evb]

@FIRE-FOX Today I should not go that way, see https://forum.mysensors.org/topic/2067/my-slim-2aa-battery-node. In the first topic you will see Update1 and to use the github project MiniCore. Much easier to use!
In the readme of the MiniCore github you will find how to install and how to use.

hi,
i am using pro mini, i installed the blink code, pro mini does not work at 2.3v. I burned minicore bootloader(1Mhz-1,98).
my purpose: running pro mini up to 1.8v and saving power.
The blink code continues to run. no longer working pro mini 2.3V. but I can't upload new code.
What can I do to use it again?

@emre299 Did you changed the upload speed in boards.txt?

@emre299 did use the Minicore project, so that is different. See my comment just above his.

@emre299 can you describe the steps you did? step by step
Which version of Arduino IDE did you use?
Without more information, it will be difficult to respond to your question.

Hi @evb and @electrik ,

First of all, for checking purposes, i installed the blink code to pro mini 3,3V with the ISP method(arduino nano). My goal is not to use the stupid booster circuit and using arduino up to 1.8v
I added arduino ide(1.8.13) minicore.

Then i chosed;
Board: minicore->ATmega328
Clock: internal 1MHZ
BOD: 1.8V
Arduino as ISP and Ctrl + shift + U
Then Blink works at 3.3v (but a little slow) but didn't work with 2.3v to the arduino.

Then;
Board: minicore->ATmega328
Clock: internal 1MHZ
BOD: 1.8V
Arduino as ISP and burn bootloader.

blink works well at 3.3v and 2,3v but now it gives an error when uploading new code to the arduino.I haven't made any other settings.

what is missing Is the minicore method wrong?

Thank you for your help.

[evb]

Ok, you programmed the blink sketch the first time via the ISP way of uploading

• the pro mini at 3.3V : works
• the pro mini at 2.3V : didn't do anything ==> this is already strange, it should also work

Then you did the same using the default way by uploading the sketch via the bootloader

• the pro mini at 3.3V : works
• the pro mini at 2.3V : works

And now you can't upload anymore new sketches to the pro mini.
Of course you upload your sketch with the pro mini again at 3.3V?

Further I should:

• double check your wirings
• is your programmer connected with fixed pinheaders or by folding the programmer a little in the holes of the pro mini? Verify if you have strong connections.
• Reprogram the bootloader. If this works, you should be able to upload a sketch.

Post some photo's that we can see something.

@evb
hello, yes, it gives an error while loading code right now (Pro mini 3.3v 1 mhz minicore bootloader).

i checked my cables 2 times. I already have a board for ISP code.!

Is there any detail picture you want? do you think the boot loader might be broken while writing

[evb]

@emre299 when you click on Burn Bootloader, you get these errors

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x03

So you verified the connections. Did you verify also with a multimeter? A wire can be broken internally

Do you have another pro mini to verify the connections?
I would try different settings like the normal settings 3.3V and 8Mzh externally, etc

If this does not work, I have no ideas anymore...
