Does u-boot support Write access to MMC/SD devices? I know it supports reading because the version I have from OMAP 35x SDK allows booting the linux kernal from MMC/SD card. From previous thread I believe the answer is no for writing in a filesystem's format (i.e. fat32 or ext3 for example). Is there a method to do "raw" writes?

(This is essentially a repost from a few weeks ago - I never got any response so am trying again.)

Thanks, twebb
