problem with writing of SD on a A10

[espace]

Good morning, I have a problem with writing of SD on a A10.
Randomly, some files on the sd are written incorrectly. I read that the problem may be related to the clock of the ram or cpu. The operating system is openwrt.
Can you help me?
Thank you

Could also be a bad SD or bad power.

Are you using an openwrt image made and supported by Olimex?  If not then try an appropriate place for support.
