AM625: AM6204: Boot from QSPI NOR and Load Filesystem from emmc

Tool/software:

Hello, 

We have a specific use case for a project, where we need to boot by default from NOR and only later load linux filesystem from the eMMC. 

Bootmode pins shall be configured to QSPI

Is there support available for having u-boot pull the linux image from the eMMC?

    Hello,

    The U-Boot by default boots the Linux from the MMC (eMMC or SD) device only based on the "mmcdev" & "bootpart" environment variables. Assuming you have flashed the rootfs to eMMC UDA 1st partition, the following commands when run from the U-Boot prompt will boot the Linux Kernel from there.

    => setenv mmcdev 0
=> setenv bootpart 0:1
=> boot

    Regards,
