this is the post I had in the old thread that is already closed. I mentioned in that post the board didn’t come up even after modifying the files.
I just tried again after applying the overlay, and set eeprom.cvb_eeprom_read_size = 0 for both tegra194-mb1-bct-misc-flash.cfg and tegra194-mb1-bct-misc-l4t.cfg and got the same error above.
