Booting Xavier AGX from SD card

Hi everyone,

we want to boot the Xavier AGX (with the development kit carrier board) from SD card to be able to quickly swap software releases. We followed these instructions, however while flashing succeeded, booting was never successful. Instead of the Ubuntu login, we get:
cannot set terminal process group (-1): Inappropriate ioctl for device

Looking at the file system it also looks very minimal and does not look like the rootfs that was copied to the SD card. Since others seemed to be successful I must be taking a wrong turn somewhere.

Any help is greatly appreciated!


Please use method from here.
