By following Jetson/L4T/Boot From External Device - eLinux.org steps,My NX is success to boot from SD card rootfs,but Ubuntu need to be “System Configuration” to start desktop.And I use my full backup system.img to reflash sd card rootfs: sudo ./flash.sh jetson-xavier-nx-devkit-emmc external,and I still got the same issue.
So how to flash a full backup system.img to NX external sd card?
you may enable -G <file_name> options to reads the boot partition and saves the image to the specified file for backing up system image.
please check developer guide, here’s a session To clone a Jetson device and flash, it demonstrates the sample pipelines.
thanks
Hi,
I got error when finish flash sd card and system restart:
mount:wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error
In some cases userful info is found in syslog - try dmesg | tail or so.
And when I finish flash NX emmc and system restart, still the same error:
mount:wrong fs type, bad option, bad superblock on /dev/mmcblk0p1, missing codepage or helper program, or other error
In some cases userful info is found in syslog - try dmesg | tail or so.
If I use a USB-MircoSD converter to flash sd card,which flash step I should follow?
And if I use NX sdio hw interface, which flash step I should follow?
you may check driver’s device names for confirmation,
for example,
USB device should show drive’s device name as /dev/sdb,
SD card device should shown as /dev/mmcblk*
