Booting Jetson Xavier with/out micro SD card

[SpaceborneEdgeAI]

I am unable to boot the carrier without a SD card after following the instruction below.
Change Root File System to SD Card Directly | Forecr

After rebooting, the board boots only with the presence of the SD card.

I tried the following extlinux.conf:

TIMEOUT 30
DEFAULT sdcard

MENU TITLE L4T boot options

LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
INITRD /boot/initrd
APPEND ${cbootargs} quiet root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyTCU0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0 rootfstype=ext4

LABEL sdcard
MENU LABEL primary kernel
LINUX /boot/Image
INITRD /boot/initrd
APPEND ${cbootargs} quiet root=/dev/mmcblk1p1 rw rootwait rootfstype=ext4 console=ttyTCU0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0 rootfstype=ext4

I tried to replace the root=/dev/mmcblk0p1 with UUID or PARTUUID of the eMMC, but none of them worked. Without SD card, it is just stuck at the booting stage.

I only found the following issue related which does not really answers the question of mine.

Jetson AGX Xavier boot from Micro SD

Well, it seems that I don’t have the Linux_for_Tegra directory. I looked for it during a while and couldn’t find it. I supposed that if I don’t have this directory I can’t access to rootfs. Am I correct?

Hi,

Please dump the full booting log from serial console so we know what’s going on.
Don’t just give a screenshot that’s cropped and does not contain much useful information.
