Boot NX from external device failed


I have a Jetson Xavier NX on a carrier board with a SD slot on it (it is the AverMedia EN715 carrier board). I would like to boot Xavier NX from SD card. Thus, I followed the steps described here:
I used L4T version R32.4.2.

After having flashed the board from a host computer (mini-USB connection), I’ve got a success message on host terminal.

*** The target t186ref has been flashed successfully. ***
Make the target filesystem available to the device and reset the board to boot from external sdcard.

However, when board reboots I got the following message on the monitor attached to the board (HDMI):

imx219 10-0010: imx219_board_setup: error during i2c read probe (-121)
imx219 10-0010: board setup failed
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

Does it mean I’ve missed some step during the Booting From External Device procedure? Is this procedure also valid for Xavier NX?
Or may it be anything wrong with my board?


This error symptom indicates the filesystem (rootfs) is not mounted correctly.
Dump the serial console log will help tell us what is going on.
