Hi John Linn,

We are using ML507 EDK 10.1 with latest SP2.
We have took your help in getting up the Xilinx git kernel up on ML507
using bsb image donwload.bit from xilinx website and dts file part of
the kernel. The kernel boots successfully. thanks for all your support.

Well we now want to modify bsb image by creating new download.bit using
EDK 10.1 SP2 and generate dts file for it.

Problem now we are facing is we follow the steps mentioned XIlinx ML507
pdf to create donwload.bit and generate dts file for it. using the same
xilinx kernel but the board doesn't boot.

Can you throw some light on any specific steps we are missing apart from
the pdf mentioned to create bsb image download.bit and corresponding dts
file. 

Just we need to use uartlite instead of 16650 uart.
Also we are trying on ML403 we are not able to create a sample
donwload.bit which boots. 
Please mention any steps we are missing or any pointers will help as we
are stuck in this problem from long.

For ml403 we even tried older edk 9.1 sp2 , 8.1 sp2 and 7.1 sp2 neither
works .

Waiting for your inputs 
Thanks In advance 
Regards
Neelu
