[microblaze-uclinux] No ROM/FLASH Board

["Bruno Herrera" <bruherrera@xxxxxxxxx>]

Hello All,

I'm finishing a port of uCLinux to a Celoxica board that I do not have
direct acess to a Rom/Flash memory. In fact I only have access to it
thru on CPLD, so I discarded it from may BSP.

Now I'm trying to boot the board but I got this(see below). I have
googled a lot but could not find any conclusive solution. Do you have
any sugestions??
