I’m trying to flash Jetson Agx Xavier Devkit to boot from an SD card but after flashing it’s not able to boot, just a black screen with a blinking cursor is showing, these are the steps I followed:
Formt the sd card as ext4 format.
Copy rootfs files to the sd card
plug in the sd card to the jetson in recovery mode and connected with type C USB
Run sudo ./flash.sh jetson-agx-xavier-devkit mmcblk1p1
Yes that what I did I formatted the sd card then copied rootfs files but at some point we need to mount the sd card and run the flash script this what the community suggestions says, could you give more more details ?
