Unable to recover NRF52832 running correctly with the last code flashed into.

[Leti]

Hello! I have a custom board with a NRF52832 chip that is working fine with the last program I flashed into. But since yesterday I can’t access it to load a new code (flash again) and neither I can’t recover it.

I’m using J-Link and I have tried to recover it by nRFgo Studio and also with nrfjprog.

The versions I have are these:

         Debugger SEGGER J-Link EDU: v10.10

         nrfjprog.exe: 10.6.0

         jlINKarm.DLL: 6.62d

         nRFgo Studio 1.21.2.10

Although my problem started with other older versions.

When I try to load the new code by KEIL I get these error messages:

And when I try to connect, erase or recover it by nrfjprog I get the following messages and log files:

I have read many questions from the forum and no answer was valid for me. I don’t know what else to do and the problem is that I don’t think that my micro is broken because it is running the last code that allows me to even connect with its BLE.

 

My code is based in the “ble_peripheral\ ble_app_uart” example of nRF5_SDK_12.3.0_d7731ad sdk. And before this last code I was loading one that tried to change the flash using the FDS library but without success.

 

May I have removed something of the flash that is needed for being able to erase or recover the micro?

I would appreciate any help. Thanks a lot.

Hi,

It looks like the debugger cannot find the device. Is it powered correctly, and is the SWD pins correctly connected?

The --coprocessor option should not be used with nRF52 devices.

Best regards,
Jørgen

Did you flash some firmware running the watchdog? Please see this errata. 

Do you have a different debugger that you can try? Can you post an image of your setup and connections?

We don't have WDT enabled so the answer is no.

Jørgen Holmefjord said:

Yes. We have another and we have test with both of them with the same results.

Jørgen Holmefjord said:

Sorry. I don't understand what do you exactly want. Do you refer to the schematic?

Can you still try to run the recover command in nrfjprog multiple times, to make sure there is no issues with getting the debugger connected due to this errata.

I mean an image of how you have powered the board and how it is connected to the debugger.

Which application image did you flash to the board before the issue occurred?

Right now I really don't know if I lied to you. Now I am no longer able to connect with the target from the J-Link RTT Viewer. In fact I think now my target has definitely dead because I don't see a correct running. But I was able to program it many times so I understand that it was correctly powered and correctly connected, or shouldn't I?

May be only those pins broke. But do you know possible causes that can cause that?

I tried with a .bat with a loop. And it ran more than 200 times.

:loop
nrfjprog --recover -f nrf52
goto loop

The last version of my custome code. It is based on one of the ble_peripheral example.

In a photo you are not going to see to much. I also attach the schematic related to this.

Power by a battery.
