We're designing a board with an AM3358 SoC and an eMMC for storage. We would like to take advantage of some of the features of the eMMC, like the two boot partitions and the RPMB partition.
Most of the information I can find on, for example, partitioning the eMMC (even from u-boot) is in regards to creating a "normal" partition table in the user data area, but not repartitioning the eMMC itself. So, here are some questions I'm hoping to get answers to:
- Does the AM3358 support booting from the eMMC boot partitions, or just from the user data area? The technical reference manual doesn't seem to be using the exact same terms from the JEDEC standard, and "raw mode" doesn't seem to mean "eMMC boot partition mode".
- Does u-boot support the first-time programming of the eMMC partitions? Like I mentioned above, it seems like this is just for creating your normal disk partition table. I'm starting to think we'll have to create our own bootstrapping tool.
- Are there software tools or existing libraries to help work directly with the eMMC? I realize this isn't a TI specific question...
