We have a custom made AM335x board I'm working on and I have encountered
a problem when mounting an ubifs image from nand. If I ...
(1) Write an ubifs image to nand
(2) Mount the ubifs image
(3) Repeat step (2)
... this then corrupts the ubifs image.
Below is a full log.
Can anyone help ?
Regards
Mark J.

Please try to write with sub command trimffs. The command looks like
nand write.trimffs 82000000 200000 81f000
If not has trimffs sub command, please add CONFIG_CMD_NAND_TRIMFFS into
board configuration file.
