sd boot problem

Hi ALL,

            We use the latest PSP with our TI8148 board,and both kernel and u-boot can detect&mount SD card,but we have trouble with booting from sd card(have set the bootmode to SD  ),after power up,we got below:

  Uncompressing Linux... done, booting the kernel.

It seems the info is  from kernel image,we make the boot card with sudo ./mksd-ti814x.sh /dev/sdd MLO u-boot.bin uImage nfs.tar.gz,and MLO is the u-boot.min.sd(renamed),also all the images are based on quick mmc with compile(PSP-04-01-00-06)


Any ideas,thanks.
