Hello,
Using an nRF52833dk and following this documentation https://github.com/makerdiary/nrf52840-mdk
I was able to flash the blinky example on my board, but only once. My problem here is that the board seems to be unreliable: around 1 time out of 50 works for the flash (I only switch ON and OFF), and all the other times I get this error:
make flash DONE nrf52820_xxaa Flashing: _build/nrf52820_xxaa.hex nrfjprog -f nrf52 --program _build/nrf52820_xxaa.hex --sectorerase 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. make: *** [Makefile:141: flash] Error 33
