Booting under MMC0 management via NAND and eMMC

Naum Grutman

Since there are some limitations with booting using 4GB eMMC under MMC0 management as described

within 26.1.7.5.2 from the AM335X TRM Rev. L 

Will this option work ????

1. if we will have MMC0 that manages both eMMC and NAND
2. Partition with MLO and u-boot.img is stored within NAND
3. Partition with targetNFS is stored on 4GB eMMC

Booting will start from NAND and continue with targetNFS portion from within eMMC-4GB

or this option is also forbidden under section 26.1.7.5.2

Maybe somebody tried it and can share the results...


Thanks,

Naum Grutman

    The restriction is only for booting from eMMC. Once the kernel MMC driver is loaded there are no restrictions for using an eMMC on MMC0.

    You cannot have NAND connected to an MMC port. For pins used for NAND boot see section 26.1.7.4.2.2 from the AM335X TRM Rev. L.
