Our hardware board design is mostly based on the SabreSmart Board( CPU use Dual, DDR3 same, Ethernet same,etc), but the sd card circuit design is different.
We use the micro-sd card which is the same with Sabre-Lite hardware design, and our board is only supported by booting from SD3.
Here is the circuit design difference:
Our Board design:
SabreSmart Board Design:
The SD3 data line, we only use 4 data line. My u-boot baseline is the SabreSmart.
My question is what should I changed from this circuit design changed based on the sabresmart uboot codes?
Thank you for your strong support!
