Hi,
i 'am trying to build a sd card with Linaro from scratch. I have been to able to generate my boot.bin with first stage bootloader, bitstream and u-boot (from xilinx repository). I also have compiled my kernel (lastest version in xilinx repository) compiled the devi-tree file supplied with the kernel and setup my uEnv.txt with bootargs and bootcmd.
U-boot can load the kernel and boot it, but as soon as the kernel tries to mount a filessystem from sd card it crashed with the following message :
VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6
Please append a correct "root=" boot option; here are the available partitions:
0100 16384 ram0 (driver?)

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I first suspected that the default device tree config for zedboard does not have a correct clock configuration for the sdhc peripheral. But adding clokc frequency to the dts file did not work. Any idea of what i'am doing wrong ?
Thanks
