I attached an external nRF52840 to the debug out port of the nRF 7002 DK (as seen here), but cannot get a connection to the external uC.
I know the cable and uC work, since i programmed them via another JLink adapter.
When issuing `nrfjprog -r`, the external microcontroller restarts, the on-board one doesn't, so the reset line seems to work fine.
No communication through SWD happens, though.
Using the DK gives me this error:
[error] [ Client] - Encountered error -102: Command connect_to_emu_with_snr executed for 845 milliseconds with result -102 ERROR: Unable to connect to a debugger. [error] [ Worker] - An unknown 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.
To me, it feels like the SWD traces are connected to both controllers, the on-board and the external at the same time, which breaks the connection.
Without the external connection, I can control the on-board controller just fine.
