Hi el.ign,

No errors from the MMC kernel driver. The only errors are related to the filesystem(s) when they are mounted.

I do see differences in the MMC controller registers and I'm testing with changes now.

The part number of the eMMC device is MTFC4GACAANA-4M IT.

Thanks,

Ren

Hi Ren,

Based on my checking, the part number was not really tested thus we are unsure the full compatibility with the latest kernel, I will check further for any information from our internal team, but it will take some time.

If you could share the any information regarding the MMC controller registers, that would help.

Also could you share what sort of file corruption that you are seeing? Or if you could screenshot it if that is easier for you.
