SD card and eMMC flash connected on AM3874

Other Parts Discussed in Thread: AM3874

Hi,

If I implement the SD0 to connect to a MicroSD cage and maybe SD1 or 2 to an empty eMMC flash, configure the AM3874 to boot up from the SD interface.

When I insert a SD card with the uboot code in it, upon power up, will CPU boot up from the SD0 first which means the uboot in the SD card gets booted up?

What if I switch the order around, SD0 to an empty eMMC flash and SD1 or 2 to a MicroSD cage with the uboot code in the SD card? Will it still boot up?

 

Regards,

pb
