Problem to upload to nRF52-DK

Hi Pedro,

Could you send us the hex file that generated from the example ? Especially if you still have the hex that you used to flash on the board ?

We are suspecting that the example may trigger manual system reset too early or enable WDT that can trigger a reset too early.

Here is a quote from our R&D team:

It seems that the recover hardware mechanism does not work as intended.

nrfjprog writes the device CTRL-AP.ERASEALL register, but the CTRL-AP.ERASEALLSTATUS flag never indicates that the operation has been completed.

No nothing special https://docs.platformio.org/en/latest/tutorials/nordicnrf52/zephyr_debugging_unit_testing_inspect.html#tutorial-nordicnrf52-zephyr-debugging-unit-testing-analysis

Hi Pedro,

I did a test here and I had the same NRF51xxx_xxAA_REV1 return if I do --deviceversion after the nRF52 chip is protected (a power reset after programming). I assume this is normal because the chip is protected.

However, I can do --recover without any problem on my DK.

So there must be something wrong that wouldn't allow nrfjprog to recover your DK.

Is there anything special about the PlatformIO firmware that you flashed on the board ?
Prior to the firmware you flashed, did you flash any firmware from our NCS SDK or nRF5 SDK?

output from nrfjprog:

This are also the logs from nrfjprog and from nRF Connect for Desktop programer:

Thanks for the info. Seems that the board is still alive.

Please send us the log/screenshot you have when you call nrfjprog --recover -f NRF52

Also please try installing the nRF Connect for Desktop and then open the Programmer app inside.

This is the board:

Yes I can see the DK in the Device Manager and I can see the led on next to the programmer chip:

This is the output from "nrfjprog --version":

nrfjprog version: 10.17.3 external
JLinkARM.dll version: 7.70c

Hi Pedro,

Please let us know which nRF52-DK board you have. Please take a picture.

Secondly, please check the nrfjprog version you have. Please do nrfjprog --version

The current version is 10.17.3

If you don't have the latest version, please try to download it here.

Also please let us know the JlinkARM version that reported with the same command.

When you plug the DK into the PC do you see it in the Device Manager, would the LED next to the programmer chip turned on ?
