demo-image-base not booting

[sudharsan122]

Hi all, i have built a demo-image-base using the tegra-demo-distro by the OE4T and i have done the flashing part with ./dosdcard.sh with sd card inserted in host pc and after that ./doflash.sh with sd card inserted in the NVIDIA Jetson nano by putting it in recovery mode. both processes completed succesfully but the board is not booting. i tried connecting a USB-TTL converter and it showed nothing. since it is a base image with no graphics im not able to find out where the issue lies

. im also attaching the logs during the processes.

Does it show nothing during the flashing process also? If so, then you probably have it connected incorrectly. Double-check that the USB serial adapter is 3.3V TTL, is actually working, and that you have RX, TX, and ground connected to the right pins on the Nano's button header. You should see some output on it during the doflash.sh flashing process.

The attached logs look OK, and I assume you're using the kirkstone-l4t-r32.7.x branch here for your builds, which should be working.
