hello,
below is the error experienced.
nrfjprog --family NRF52 --eraseall
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.
Makefile:535: recipe for target 'flash' failed
make: *** [flash] Error 33
does the nRF52 DK have problems in win10 running under a UBUNTU virtual box? that is what i am using.
DUT interfaces via the level shifter to the power pins port. this is a nRF52840 device.
part of log file says it cannot detect the 840 so it defaults to the on board 832 device at that point.
here is portion of the log file;

jlinkARM.dll is 6.44e
is this common error and what is your suggestion solution?
