Hi Guys,
I am using an IXP435 and trying to program the USB controller on it.
The environment is Redboot.
In the current redboot, I am NOT able to access the USB base address
i.e. 0xCD000000.
Actually, I am not able to access any address beyond 0xC80FFFE0.
Is there any ixp initialization or redboot initialization that I have
to access this registers space.
Thanks for the help.

Sure, look at the code which sets up the MMU. It is in the HAL for
your target.
