Hi
Iam having problem with my custom board,while booting it hangs on Waiting for root device PARTUUID=22e9258b-02...
it seems the kernel didnt find my memory card file system
i have checked all the below mentioned pheripherals with bare metal code all seems to work
1,OMAPl138 jtag test
2,DDR
3,ETHERNET phy
4,USB
5,UART console
6,emif with fpga
7,emif with 8 bit nand
8,SD card slot with the card detect pin changed to gpio[1] instead of gpio[0]
but when i run linux with latest processor sdk provided it hangs at Waiting for root device PARTUUID=22e9258b-02...
i have given below the complete linux boot prompt below

Waiting for root device PARTUUID=22e9258b-02...
it seems my nand flash did not get detected ,but it also works in bare metal
and here is my sd card slot connection details below
i did even build the device tree, it didnt work ,so please help me to solve the problem
