Hi, there,
I boot linux (2.6.3) on my ppc 8241 through vxworks bootloader. I'd got
a port (on address 0x70020006) to constrol three LEDs, so I could know
where the kernel going. But after the disable_mmu is called, I lost
control to the LEDs, Any suggestion on this? As I know, vxworks use a
one-to-one mapping MMU setup, I should must constrol the LEDs through
the same address.

Thanks for any suggestion.
