[U-Boot-Users] U-Boot on MPC8280

[Matias Sundman (AL/EAB)]

Hi Wolfgang,
Do you think that the Windriver equipment ( e.g. VisionPROBE ) is of low quality?

When looking at the demos, they have been looking a bit sharper than e.g. the BDI2000.

Regards // Matias

As pointed out many times before this is probably  not  a  good  idea
unless you know exactly what you are doing and how U-Boot is working.
If this is one of your first ports of U-Boot and/or if you don;t know
the  processor  really  well  I  recommend to use the standard way of
booting from flash instead.

Maybe your debugger is not working as expected...
