AM69: The uboot issue for AM69

Zhang Liang

Part Number: AM69

Hi,

We use the AM69 and debug in the SK-AM69, now we have below technology support need:

We need the partitioning eMMC from U-boot, we consider to initialize the eMMC, and then debug the uboot, roofs and Kernel and so on;

1. We want to use the partitioning eMMC from U-boot and we can't serach how to load the rootfs and kernel, the below is the link:

3.1.1.5. SD, eMMC and USB — Processor SDK Linux for AM69 Documentation

2. Follow up the above step, and we use the DIP switch to choose the SD card mode or eMMC mode, and the SD card mode print information is normal, and the eMMC mode has no any infromation feedback.

3. CAN you help to provide the mksdboot.sh file that we can't serach in the SDK and EVM, thanks.

mmc partconf 0 1 1 1
mmc bootbus 0 2 0 0

gpt write mmc 0 ${partitions}

Please execute the above from U-Boot prompt.
