hello Elektrische,
please flash the board for the first time.
assume this brand new Nano platform is able to boot-up when flashing via SDKManager.
BTW,
there’s a background service executed after the system boot-up,
you may check /opt/ota_package/bl_update_payload.log for the details to make sure the update is finished,
it makes a failure if you power-down the device in the short while, (i.e. within 5~10 seconds) for Nano-SD.
thanks
