at91sam9x5: mmc: save environment as a file in FAT partition.
PATCH 1/1 at91sam9x5: mmc: save environment as a file in FAT partition.
This patch will save U-Boot environment as a file: uboot.env, in FAT partition instead of saving it in raw sector of SD card.
Since saving environment in raw sector has risk of corrupting the SD card and only can use very small size.
Save as a FAT file has no above limitation.

When I test this on at91sam9g35ek board, execute "saveenv", it will report following information, any information for this?

I also tested some sd card, and I meet this issue you met too. In such situation, the command "mmc part" will report a unknow partition error.
I suspect the issue is caused by either mmc driver or FAT partition part of code.
And I will continue digging this issue. Thanks for report the errors.
