Copy a large file into EMMC flash shows an error message

Embedded Devices Linux

Hi,

I have ccimx6ulsbc dev board and dey 2.2-r2

When I call tar command to unzip a large file (15MB zipped size, about 50MB unzipped size),

I got the following error:

EXT4-fs (mmcblk1p1): last error at time 4297: ext4_mb_generate_buddy:757

I also did another test: (27MB)
Copying a large file into emmc flash causes this error message. (not always, but happens)
Copying the same file into internal NAND flash is ok.
Copying the same file into a USB stick is ok, too.

Any suggestions?

Thank you,

David Zhou

It looks like your filesystem may be corrupted.

repairing the FS should fix the issue.
