Re: [microblaze-uclinux] Please, I need your help about petalinux and the U-boot bootloader

[Benny Chen <bennyc@xxxxxxxxxxxxxx>]

Hi John O,
Your problem may be with your U-Boot image.  It must be linked to a 
different address to your hardware address maps.

Do a mb-objdump -t on your u-boot.elf image and you should see where the 
code is linked.

The root of your problem may be that you are trying to build an image 
for your platform using the Spartan3E reference design without doing a 
petalinux-copy-autoconfig to propagate your hardware configurations to 
the build framework .

Your  best bet is to to just add your platform to PetaLinux and all this 
problem will go away.
