    We have not tested uBoot in SATA. We only use uBoot from SPI or SD card, but there is no difference between these two (SPI or SD) - they are same uBoot image.

    What we do, we often boot from SPI and then run this command to test a uBoot on SD card:
    Code:
    mw.l 0x020d8040 0x2840; mw.l 0x020d8044 0x10000000; reset
    There is not much information about these registers, you will need to figure out by yourself how to switch between different SD cards (I think I read somewhere, that you may be able to use the similar command to boot up from SATA too, but I am not 100% sure about that). Of course, the original first uBoot is always loaded from eFuse setting.
