Hi, I created a blinky sample for the ProMicro board. Entered the flash mode as mentioned in https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/boards/others/promicro_nrf52840/doc/index.html But when dragging the uf2 file into the NICENANO drive, the red led will blink fast, no matter what I used as a SLEEP_TIME_MS. It looks like the application is crashing. What could be wrong?
I tried both with and without ONFIG_BOOTLOADER_MCUBOOT=n
Regards,
Bob
