Waiting for root device /dev/mmcblk0p1...   (BF548-EZKIT)

Hello,

 

I'm having two issues on booting uclinux on my bf548 board:

 

1. "register bfin atapi driver" is failing

 

I'm not sure if the above is causing the following:

 

2.  Waiting for root device /dev/mmcblk0p1...

 

In the serial output though I see the following which I believe is causing problem 1:

 

"peripheral_request: Peripheral 80 function 1 is already reserved by bf54x-lq043 !"

 

I'm attaching the .configs and serial output.

 

Please let me know how I can solve the above issues I'm having.

 

I followed the instructions for building from here:
