GUIDE - NRF5 / NRF51 / NRF52 for beginners

ileneken3

Yes, I understood what you meant. I will only do the "Export compiled Binary" from the IDE, and leave the drivers as J-Link commander or nrfGo Studio wants them.

In: https://www.openhardware.io/view/376/MySensors-NRF5-Platform it says:
"Currently, the nRF52832 and nRF51822 are supported so we recommend sticking with those for now."

I noticed that my board: (E73-2G4M04S) is labeled "NRF52810". So is that why after programming it nothing works (nothing seen on gateway) :( ?

If so, I messed up on that order.

But I am also trying the E73 2G4M04S1B, which at least from the AliExpress order
https://www.aliexpress.com/item/CDEBYTE-E73-2G4M04S-BLE-4-2-5-0-long-distance-100m-2-4GHz-SMD-ARM-Core/32820692238.html?spm=a2g0s.9042311.0.0.27424c4dSKBLn7

says it is nRF52832. (It isn't labeled on the board though). For this module, I can't unlock it using "Recover" from nRfgoStudio. It always fails with a message "Recover failed: Unknown error".

From the command line, if I do

nrfjprog.exe -f NRF52 --recover --log

and it comes back immediately with:

Recovering device. This operation might take 30s.
ERROR: Recover failed. Please make sure that the correct device family is given
ERROR: and try again.

The key error from the log seems to be:

2018-Dec-27 12:25:22 . . . . . nRF52_power_debug_and_system_regions
2018-Dec-27 12:25:22 . . . . . . nRF52_write_debug_port_register

2018-Dec-27 12:25:23 . . . . . nRF52_power_debug_and_system_regions: JLinkARM.dll CORESIGHT_WriteAPDPReg returned error -102.

If I do: nrfjprog.exe -f NRF51 --recover --log

it actually makes LD5 on the DK board flash for 30 seconds, but still returns failure with the exact same message.

Any other tricks for "recover/unlock" of those boards?

Thanks!

@ileneken3 I suggest posting a query on the nordic devzone forum. A Nordic engineer will get assigned to it and give you an answer. I've tried this a few times, and I had good luck with it. Generally 24 hour turnaround on weekdays, and no answers on weekends. So, if you post it now, you may get an answer tomorrow. It's in Nordic's interest to help developers unlock these chips, and if there are any secrets to doing so, Nordic will certainly know them.

It sounds as though once you get past the unlock issue, it will be easier for you.

@ileneken3 sorry, can't help you anymore.

I can only tell that I installed the segger drivers, and everything as described by @d00616

Most issues I have, happen when I did some soldering wrong or when I've been messing around with drivers. A clean setup almost always solve my problems

I used both old and new ebyte modules and they work like a charm.

Hi,

I'm trying to begin with nrf52832.
I have follow advice, with soldering 4 wires. I use STlink v2, downloading soft before use it.
When i try to erase the nrf52832, with sketch "mass_erase" in exemple, i have the following error :

@sancho119 what exact model of a board do you have? Did you try to switch SWDIO and SWCLK, maybe they are messed up? Or lose connection? To erase softdevice you can simply chose Tools>Softdevice>"None" and then press "Burn bootloader" button.

Sancho119

Hello
it's a E73 2G4M04S1B from EBYTE
When i switch SWDIO and SWCLK, i can see the led of STLink V2 changing from red to blue, but when i try to uplod empty sketch (MyBoardNRF5), i have this error :

@sancho119 No matter what I tried, I could not unlock the E73 with the STLink.

I had to buy a jlink clone, download a bunch of segger debugging tools, use the segger tools to override the lock flag. After that I could flash the bootloader.

https://github.com/micooke/arduino-nRF5-smartwatches/blob/master/nrf52_disable_read_protection.txt

#To share my experience with the nRF52832.
#I was unable to disable the read protection / flash lock with a BMP or ST-Link V2, but i was successful with a J-Link.

#When nRF52832 chip is read protected / locked, the first step is to try:
nrfjprog –recover -f nrf52

#This performs the same task as:
Jlink -if swd -device nrf52
J-Link>SWDSelect
J-Link>SWDWriteDP 1, 0x50000000
J-Link>SWDWriteDP 2, 0x01000000
J-Link>SWDWriteAP 1, 0x00000001

#Wait until AP 2 is 0, and the operation is complete
J-Link>SWDReadAP 2

#If two successive reads from AP 3 produce 0, then 1 then protection is disabled
J-Link>SWDReadAP 3
J-Link>SWDReadAP 3

#Tested with JLink v6.20b

@ncollins have you tried this: https://github.com/AndruPol/nrf52832-recover ?

ncollins

At the time, I did not have a BMP or any STM32 capable of being flashed as a programmer.

I figured the jlink clone might be useful in the future, but I definitely think the BMP / diy programmer is the way I would have gone if I had one sitting around.

Sancho119

@ncollins
@monte
thx for these advices.
I think i will try with BMP clone (STM32F103C8T6), cheaper than J-link (i must only wait 1 month to have it, buying it in china...)
is it possible to erase E73 with BMP in win10 ?

Hello,

Some news !
i buy a Jlink, and success in erase my nrf52832 with nrf prog, using method of berkseo.

Next i try to upload a basic sketch (blink) :

#define MY_RADIO_NRF5_ESB

#include <MySensors.h>

void setup() {
Serial.begin(9600);
hwPinMode(LED_BUILTIN,OUTPUT_H0H1);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

I think its good, but when i put a led with a resistance on P0.08, nothing :(

LED_BUILTIN corresponds to po17

Hi. Are the steps in first post still valid please?

I'm trying without luck to get first nrf52 programmed. I get a weird error"Error resolving FQBN: missing" in Arduino IDE when I try to verify any basic sketch, even blink. Thanks for any thoughts

ncollins

@p359 Which version of Arduino IDE are you using? I was seeing that with 1.8.10, but I ended up downgrading to 1.8.6 to test and it worked.

p359

@ncollins 1.8.10 also. I'll try then 1.8.6 tonight. Cheers for the idea!

Hi,

Is it possible to get Serial output in Arduino IDE for nRF52 boards with J-Link OB 7.0? Or do I need a newer programmer? Or maybe I can get it with ST-Link v2/v2.1 somehow?

Thanks, I've seen it before. In my case a programmer is easier solution - I don't know yet how to re-assign TX&RX pins in Arduino on my EByte 52840 module and in specs for that module there is no info about UART connectivity.
Maybe you know how can I re-assign TX&RX pins in Arduino? Then I can solder wires to assigned TX&RX pins and connect them to USB-UART. What I've found is in Forth language ...

idanronen

Does anyone know what settings I need to use for this development board with arduino ide?
Ebyte E104-BT5032A-TB
https://a.aliexpress.com/_dT5dMb8

It has a cp2102 on board which I have the driver for. I've installed the arduino ide nrf52 board, but I can't find a programmer, board, or any other settings which will let me flash it without a Java exception or a timeout. Maybe I need to set the jumpers differently but there's no documentation on that.
OTA works fine though.
