Good Evening
I try to program the Fanstel EVM BT40F using a nrf5340 DK both boards are connected from Debug Out to Debug In 10pin connector. I try to flash the blinky example and get at almost all attempts the following failure
-- west flash: using runner nrfjprog
-- runners.nrfjprog: Flashing file: /Users/gerhard/Desktop/nordic/blinky1/build_1/zephyr/zephyr.hex
ERROR: Unable to connect to a debugger.
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.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.
FATAL ERROR: command exited with status 33: nrfjprog --program /Users/gerhard/Desktop/nordic/blinky1/build_1/zephyr/zephyr.hex --sectorerase --verify -f NRF53 --coprocessor CP_APPLICATION --snr 1050065280
I tried both at Windows and MacOS on mach OS one try of maybe 50 were successful.
Programming the nrf5340 DK works without problems.
Best Regards
Gerhard
