Every time after writing file on file system. After umount and mount again, the file will be found mismatch with original.
From TRM of OMAP3/OMAP4/DM37x, the below is mentioned about the Auto CMD12 Enable bit.
- SDIO does not support this feature. - SD card only.
So I am wondering if it is suitable to always enable the bit for multiple block transfer in host controller driver. You mean that only SD card is supported by OMAP3/4 and DM37x MMC?
I am just confused with the above, even though it may be not related with the problem reported here.
Thanks, -- Ming Lei
