Hi

why are u-boot and linux accessing SD card in 1-bit mode on zedboard? I see no reason for this? The card is connected in 4-bit compatible mode, and all applications and software should talk in 4-bit mode for best performance.

As per as in u-boot....

clone the latest u-boot from xilinx git.

We can able to detect and program through 4-bit mode as well.
