I recently tried to flash an image to 2GB with FRC.
The steps Ive followed.
I got a fresh board, booted the JP 4.5.1 image directly on SD Card from host, to test it successfully boots and ups and runs the Jetson Nano 2GB board.
But after successfully flashing the SD Card by placing the Jetson Nano Board under Force Recovery Mode. The Board never boots up.
Going back to the previous method of flashing SD Card on the host, also did not boot up the Jetson Nano 2GB board. By removing the FRC short, and simply plugging back in the SD card. Also did not boot the Jetson Nano 2gB board.
The Power LED seems to light up in all the conditions but it never boots back up anything. But nothing happens after that.
Serial log looks like this when official Image is flashed:
