nRF52840 flash dump

[frederiksnk]

Hello there,

I'm using a nRF52840. I would like to perform a complete flash dump. I have tried using an ST Link V2 and and openOCD.
It was only returning errors and the firmware on my device won't run afterwards.

I've tried using a Segger J-link as well with the

nrfjprog --readcode --log

command. This didn't work either.

Does anyone have some advice for me?

Regards
Frederik

Hello Frederik,

Try the command:

nrfjprog --readcode my_flash_dump.hex

Obviously, you can name it whatever you like. It doesn't need to be "my_flash_dump.hex".

Best regards,
