Dear NXP,

 

I am working on i.MX 6Quad SABRE-SD with Android 9. I am facing some problem when copy the some data to system/app from USB Mass Storage,

 

I got error, when I mount the system to write access,

 

sabresd_6dq:/ # mount -o remount,rw '/system'
EXT4-fs (dm-0): previous I/O error to superblock detected
Buffer I/O error on dev dm-0, logical block 0, lost sync page write
EXT4-fs (dm-0): re-mounted. Opts: block_validity,delalloc,barrier,user_xattr,acl,inode_readahead_blks=8

 

 

And also I got error when copy the some data to system/app from USB Mass Storage.
