Hardware:
nrf52840 Seeed Xiao BLE Sense connected to a segger J-link probe
Host OS: Ubuntu 20.04 LTS
Connect SDK setup is done. I am able to build firmware files and also upload them using other methods such as the DFU bootloader and using OpenOCD.
I can also connect to the target using the Jlink using j-flash and i was able to erase and reflash the board.
But the problem is that the board does not show up in the connected devices panel in VS code.
I changed the device provider in the extension settings to nrfjprog from the default nrfutil. After this the jlink serial number is showing up but I'm unabe to flash the target.
I just get this error message with no other details
Then I tried using the nrfjprog command line to flash the board, which is giving me the following error :
As you can see the j-link probe is detected by the system.
nrfjprog --ids --expand gives me this:
---------- Emulators ---------- serial number: 4294967295 connection type: USB -------------------------------
but nrfjprog --com gives me no output.
Im running the latest stable versions of all software as far I am aware of.
west flash gives me the following:
-- west flash: rebuilding
ninja: no work to do.
-- west flash: using runner nrfjprog
Using board 4294967295
-- runners.nrfjprog: Flashing file: /home/raider0ne/projects/hello_world_app/build/zephyr/zephyr.hex
