Bootloader and fuses for Pro Mini 3.3V using Arduino UNO as ISP
-
I thought I'd get started on learning how fuses and boot loaders work, so I flashed ArduinoISP version 04m3 to my UNO and connected a 3.3V Pro Mini as per the instructions in the sketch.
I then opened the blink sketch, selected Arduino Pro Mini 3.3V 8MHz as board/processor and uploaded using programmer. The upload was successful and the pro mini started blinking.
Next, I adjusted the delay to make the led blink slower and uploaded using programmer. The upload was successful and the pro mini started blinking at the slower rate.
So far so good. As far as I have understood, when I choose "upload using programmer" the default bootloader is overwritten and I can no longer upload sketches using FTDI. Therefore I selected Tools->Burn bootloader in the Arduino IDE, thinking that doing so would load the default bootloader again.
Selecting Burn bootloader seems to have set the fuses (-Uefuse:w:0x05:m -Uhfuse:w:0xDA:m -Ulfuse:w:0xFF:m). The Pro Mini now no longer blinks when powered. I am no longer able to load any sketches using "upload using programmer", avrdude gives up after a few "avrdude: Device signature = 0x000000 (retrying)" saying "avrdude: Yikes! Invalid device signature.".
I think the new fuse settings were incompatible with the Pro Mini somehow, probably clock-related.
- Is there an easy way to get the Pro Mini back to life?
- What should I have done instead to burn the standard bootloader so I could get back to loading sketched over FTDI after my experiment?
-
Use this to check your fuse settings.
In general as far as I know / did:
- Make sure you have the desired settings (standard pro mini settings should work most of the time) available in your Arduino IDE
- Load the Arduino as ISP sketch onto another arduino and connect pins 10-13+GND+Power to the right pins of your arduino (that you want to program)
- Click burn bootloader to write the bootloader and set fuses
- Disconnect that and connect a ftdi programmer (or RX/TX of the arduino I guess) and upload your normal sketch
If you use the upload using programmer you don't need a bootloader (it get overwritten anyways here).
Correct me if I am wrong here guys.If you really used the wrong fuses only the right oscillator or a high voltage programmer can help you afaik.

I have been through the same scenario. My savior was USBasp and AVRDUDESS
Select programmer and click detect. If the device signature is found you will be able to set the fuse bits. Get the fuse bits from boards.txt in Arduino folder. I prefer using AVRDUDESS rather than Arduino to burn bootloaders. Its very convenient and easy to use.

@LastSamurai that looks like exactly what I did, except that I used the Arduino as ISP sketch on the Uno. I'll try loading the avrisp sketch on the Uno instead.
@Suresh-Mali thanks for the suggestion. I'll try avrdudess as well.
-
I have recovered several pro mini just by changing to a pro mini board and "burn bootloader" in the IDE (still Arduino as ISP) - or maybe i missunderstood the question.
-
@sundberg84 sorry for being unclear. "Burn bootloader" is exactly what I am trying when avrdude says "avrdude: Device signature = 0x000000 (retrying)".
-
@LastSamurai: could you point me to where I find the avrisp sketch?
-
@mfalkvidd I am sorry I actually meant the Arduino as ISP sketch that you were using.
Did you check what your fuse settings mean with the calculator I linked earlier?

The fuse settings seem to be the default for Pro Mini 3.3V (at least according to the google hits I found). So setting the fuses and burning the bootloader should have brought the Arduino back to it's default state. Haven't had time to try avrdudess yet, will do that during the weekend.
-
@mfalkvidd As long as you have not disabled SPI fuse you should be able to recover. Try AVRDUDESS with slow speed. Also on USBasp there is a jumper for slow sck speed. That helped me recover/reprogram fuse to Blank ATMEGA328p as well.
-
I've I found the log files from Arduino IDE, so now I'm better able to reconstruct what happened. stderr and stdout are stored in different files and there aren't any timestamps in stderr so merging them is quite hard.
Step one: Writing the ArduinoISP to my Uno. Works well.

It can read my UNO (clicking detect resonds with Detected 1e950f = ATmega328P) when I use "Arduino" as programmer. But it can't read the fuses (they all show up as 0x00)
I have not figured out if I can use the Arduino as ISP with avrdudess and I have not gotten the avrisp mkii I borrowed to work either. Avrdudess says the following when I press "detect" after connecting the avrisp mkii to the Uno ISP header, when using Atmel AVR Isp mk ii as programmer:
Unable to detect MCU avrdude.exe: stk500v2_command(): command failed avrdude.exe: stk500v2_program_enable(): bad AVRISPmkII connection status: Target not detected avrdude.exe: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check.The led on the avrisp mk ii is green, regardless if the Uno is connected or not.

@mfalkvidd If the ATMEGA is detected then all you have to do is input the Fuse Bits and program. It should work. Just select the bootloader hex file in Flash. Check Set fuses and hit program.
-
@Suresh-Mali the Uno is detected, but the Uno works fine. I am not able to detect the Pro Mini, which is the one I want to load the bootloader on.
-
After more experimenting and reading I have concluded that I am clearly in over my head. I need to understand the basic concepts before I continue. @m26872 has graciously offered to help IRL so hopefully we'll be able to figure something out.

@mfalkvidd Do you have an USBasp? It works great burning bootloaders. You will be able to recover the fuse as long as you have not set the fuse to disable SPI. If SPI is disabled then the only way to recover is using High Voltage Programmer.
-
I don't unfortunately. I have borrowed an avrisp mk ii but I haven't been able to get it working.
I can absolutely buy an USBasb but if I am unable to get the avrisp mk ii to work, I will probably not succeed with the USBasp either so I need to learn more first.
-
By the way, I found http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega328p&LOW=E2&HIGH=DA&EXTENDED=FD&LOCKBIT=FF for calculating fuses. I find it easier to view than Engbedded's fuse calculator, and it is possible to link directly to any fuse settings which is really nice.
-
@mfalkvidd AVRDudess works with AVRISP mkii as well. Have you tried to detect the Pro Mini chip using AVRDudess+AVRISPMkii. Are you able to detect the chip using Mkii in AVRDudess?
-
@Suresh-Mali I have tried, but without success. See the last three paragraphs in http://forum.mysensors.org/topic/3304/bootloader-and-fuses-for-pro-mini-3-3v-using-arduino-uno-as-isp/11
-
Finally some success!
I am now able to read and write the fuses on my Pro Minis using Arduino as ISP.I have uploaded the Arduino as ISP sketch (File->Examples->ArduinoISP in the Arduino IDE) to my Uno and connected the Uno to the Pro Mini as per the instructions in the sketch. The key was to use -b 19200 as parameter to avrdude, without that I'm unable to connect.

And I'm also able to upload a new bootloader to Pro Minu from Arduino IDE using an Arduino UNO as ISP.
The ArduinoISP guide says that I might need to put a capacitor between reset and gnd on the Uno, but what I had to do is put a capacitor (0.1uF) on between reset and gnd the target Arduino Pro Mini.I don't understand why I need to do that, but uploading fails (avrdude says "verification error") 10 out of 10 tries without the capacitor. Upload is successful 10 out of 10 times with the capacitor.
This is the log from a successful upload, in case it is useful for anyone else:

The cap definitly has to on the programmer (uno) between reset and ground. Otherwise when you try to reset the target board for reprogramming you just reset the programmer (and then the programming fails).
Strange that it worked the other way.

After visiting @m26872 and getting great insights to his workflow and his projects, I can report this:
- The avrisp mk ii I borrowed from a co-worker does not work. So that's why I wasn't successful using that device. AVR Studio gave some helpful error messages, much more helpful than Arduino IDE, so lesson learned: Use AVR Studio when troubleshooting.
- Using my Arduino Uno as ISP worked fine at his place, even without the capacitor. When I got home, I tried 10 times without the capacitor and all but 1 were successful. Strange. But at least it works
- We were not able to revive any of the 4 Pro Mini i "bricked" when experimenting. Good thing they are so cheap
A BIG thanks to m26872 for helping me and for a nice visit to his home.
