Hi there,
We are using 2 NVIDIA Jetson AGX Xavier at work.
The first one was flashed during april and the second one at begining of June.
Yesterday (2020/07/09) I did apt update && apt upgrade on the first one. But after reboot, I can only see the NVIDIA logo, then blinking cursor at the top left of the screen (kernel is loaded and then, does nothing)
Did the same on the second one, just to be sure lol.
Stuck at the same problem…
Having completely reflashed the second one, and cloned the resulting eMMC content to an USB Disk, I successfully booted the 1st one using eSATA/USB port.
The problem was in the extlinux.conf file
The one which doesn’t boot :
TIMEOUT 30
DEFAULT primary
MENU TITLE L4T boot options
LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
INITRD /boot/initrd
APPEND ${cbootargs} quiet
# When testing a custom kernel, it is recommended that you create a backup of
# the original kernel and add a new entry to this file so that the device can
# fallback to the original kernel. To do this:
#
# 1, Make a backup of the original kernel
# sudo cp /boot/Image /boot/Image.backup
#
# 2, Copy your custom kernel into /boot/Image
#
# 3, Uncomment below menu setting lines for the original kernel
#
# 4, Reboot
# LABEL backup
# MENU LABEL backup kernel
# LINUX /boot/Image.backup
# INITRD /boot/initrd
# APPEND ${cbootargs}
The one that boots :
TIMEOUT 30
DEFAULT primary
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

#
# 4, Reboot
# LABEL backup
# MENU LABEL backup kernel

# APPEND ${cbootargs}
Not sure if :
- the extlinux.conf file was actually right before the update (missing arguments were supposed to be somewhere else, before the update)
or - the extlinux.conf file was messed up during the update (update deleted those arguments)
But what I’m sure about, is that in both case, it’s a problem ;)
Hope it will help
PS : not sure if it’s related, but on both of those Jetson AGX, an NVME SSD is installed (but not formatted and not used for the moment). I guess it’s not related but just in case I’m wrong, it’s better not to hide this detail.
