I followed the below link for copying the rootfs from SD card to USB3 SSD drive :
But during the copying, Nano is down and cannot boot up anymore. I tried to flash a new SD card to test but nothing happens. The LED is not lit.
I measure the voltages in the board (for both micro USB 5V-2A and the other 5V-4A) and see that the 5V is present but the 3v3 is absent.
Do you think this is a HW defect or what should I do to bring the board back to life ?
Thanks in advance,
