Hello,
I'm in a developing stage with the nrf52840 and today I got this error after trying to ensure the "--erase all" command from the nRF Connect software.
I know that this is a well-known issue, so I've already tried everything that I could and nothing seems to solve the issue.
Worths to mention, that I was able to flash it numerous times using the nrfjprog. Now, after attempting to flash it using the nRF connect software it does not work anymore.
Running the nrfjprog --recover --log gives:
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.

What can I do to solve this? The nrf52840 is still working fine with the latest firmware flashed. The issue is that I'm unable to flash a newer one.
Thank you,
Fernando Fontes
