<br>
I would need some help to understand what is the problem...<br>
I am a bit lost...<br>
<br>
The board is very similar to the Xilinx ML403 with a Virtex-4 and PPC
405.<br>
<br>
What can I provide to make the debugging easier?<br>
<br>
Can the problem be the content of the initrd RAM disk?<br>
<br>
Thanks for your help.<br>
<br>
Luca.<br>
