hello zsjalive,

there’s I/O error reported from kernel side,
for example,

[   99.531713] blk_update_request: I/O error, dev loop1, sector 0
[   99.541176] SQUASHFS error: squashfs_read_data failed to read block 0x0
[   99.547882] squashfs: SQUASHFS error: unable to read squashfs_super_block

may I know what’s the external device you’d connect to Jetson TX2?
thanks

i just connect a nvme sata device. and i can access(read and write) it .

hello zsjalive,

had you create a partition configuration file for your nvme device?
please check External Storage Device Partition for an example;

besides,
you may also refer to Flashing to an NVMe Drive to booted from an NVMe storage device.
thanks

hi，i did not create a partition configuration file for my nvme device, i only format it for savfing data.
unfortunately,
i removed my nvme device, it also prompt the same info"unable to mount volume".
i remembered that this happened after i changed file “/etc/passwd” for my username “nvidia”. in the pic uploaded!
i changed it just for log in as root when TX2 board powered on!
