Re: Porting NetBSD to the Zipit Z2 XScale handheld

[Held Bier <lausgans%gmail.com@localhost>]

Thanks to Nonaka's smart help, NetBSD now boots on QEMU-Z2, including
lcd console.

But back to the real hardware, my previous statement is not all correct:
> Ok, uimgs are now working when built from HEAD. At least I see NetBSD stage-2 loader mention on the screen.
Actually it hangs at "Transferring control to NetBSD stage-2 loader" -
text inlays and screen slowly glows up to the complete whiteness.

Robert, currently Gumstix uses:
KERNEL_BASE_PHYS=0xa0200000
KERNEL_BASE_VIRT=0xc0200000
Which I think should be safe too.
Do you have any more ideas on how to fix loading on a real device? Thanks.
