Hi,
I am trying to prgram the nRF52840 DK board (revision 2.0.1) within a virual machine (VirtualBox running Linux Mint). I have installed the SDK and the nrf command line. When I run "make flash" in the directory of project (e.g. /home/damian/Documents/nRF5_SDK_17.0.2_d674dde/examples/peripheral/blinky/pca10056/blank) the following happens:
1. The outpuit of the terminal shows
DONE nrf52840_xxaa
Flashing: _build/nrf52840_xxaa.hex
nrfjprog -f nrf52 --program _build/nrf52840_xxaa.hex --sectorerase
2. The JLink device that the nRF52840 DK board normally appears as suddenly disconnects and it halts at this last line before outputting the error
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:138: flash] Error 33
I then have to unplug and replug the DK board to make it appear again as a JLink drive. I have found that flashing the board with the MBED firmare fixes this problem and the device will sucesfully program the onboard chip. The problem here is that I am using the DK board to program an external board and when I have made the change to MBED, the debug out function no longer works. I need to be able to both program the DK in the virual linux environment and program an external board with it.
Thanks for you help
