Tool/software: Linux Hi Ti, I'm using SD card (4GB) on MMC1 and eMMC 16GB on MMC0, am335x. I had read in technical document that eMMC cannot boot MMC0 with capacity higher than 4GB. I created SD 2 partitions (boot and rootfs), and eMMC 2 partitions(boot and rootfs). I put MLO and u-boot.img to SD card (MMC1, boot partition (uuid 1:1) and rootfs (zImage, dtb, roootfile ) to eMMC (MMC0), rootfs partititon (uuid 0:2) I want to boot MLO,u-boot.img from SD card (uuid 1:1) and boot zImage from eMMC (MMC0, UUID 0:2) but fail. I think to modify uboot source code to change partititon but i cannot see that. My BSP version: ti-processor-sdk-linux-am335x-evm-02.00.02.11, uboot version: 2015.07-00067 Please help me!
