There is an issue which affects N1SDP connected via USB Debug to a host PC running Windows 10. When USB UART remote reset switch (S2-2) is set to ON and the host PC reboots, the SD card of N1SDP is stuck in a disconnect/connect loop. This issue only occurs if the host PC is rebooted.
To solve this issue please use MCC console command "REBOOT". The only disadvantage is this method does not provide the lowest level of reset to the board (MCC reset) so potentially an issue with the MCC could not be recovered remotely (need to press reset button).
