hi all,
Hello, my board(nrf5340 dk,pca10095,0.11.0,2020.45 and nrf52840 dk ,pca10056,1.0.0) often encounters the issue of "J-Link not found" (no LED(LED3)/USB not mounted).
Alternatively, it initially works
correctly for debugging and programming, but after some time(random), it disconnects((To restore the connection, try unplugging and plugging the USB cable repeatedly.), and the LED either does not light up or flashes slowly. Additionally, when programming sample code that requires higher current or the LED to light up, there is a slight Electric current sound coming from the USB or power source.
jlink error:
