Hi,

I have 2GB emmc on SDMMC1 bus.

I wish to have first 1GB (0~1GB) as application code area and the rest 1GB(1GB~1GB) as FAT file system that access by user as USB MSC. Even more, the first 1GB i wish to have 2 partitions(like A-B bank) for fail safe firmware update mechanism.

So is that possible to do that?

if not,how to use flash on xspi1 to have fail safe firmware update? like if update fail, roll back to old firmware..
