Flashing Jetson nano emmc fails

[linuxdev]

If you see a single NULL byte, then it somewhat validates the idea that the serial console wiring is at least intact. I don’t see any way the module itself is functioning if this is all it sent upon power on. In this case the module itself might be failed (which is rare…I’ve seen several carrier boards fail, but short of lightning strikes a module failure seems rare). This is probably one you could RMA if it is still in warranty.
