    Yes, eMMC is supported on AM335X. There are no size restrictions, as eMMC is connected to one of the MMC processor interfaces and from software point of view it behaves similarly to an SD card. There is only a boot restriction for eMMC on MMC0 - check section 26.1.7.5 from the AM335X TRM Rev. L for this and for booting information.

    Just a small nitpick: although physically and electrically similar (hence easily confused), from a software point of view the two are totally incompatible. Software will try the SD initialization command (which is ignored by MMC) first, and if that times out tries MMC initialization instead.
