Re: [Gumstix-users] SPI problem on Overo

Oh, the information printed is  used in my kernel.

I boot from SD card. I try your kernel again. 
However, I cannot load your u-boot.img. I copy MLO, u-boot.img and uImage to
my first partition.

The booting log:

I try to change your u-boot name u-boot.img to u-boot.bin, I don't know the
difference.
stop at *Loading u-boot.bin from mmc*.
