[Skyeye-developer] pxa_lubbock or pxa_mainstone

[kashin Lin]

Hi,

i build OKL4( a microkernel) for xScale pxa-270 and use skyeye to simulate.
when the skyeye configuration is :
cpu: pxa27x
mach: pxa_lubbock

it works fine. like following:
=================================
arch: arm
cpu info: xscale, pxa25x, 69052100, fffffff0, 2
mach info: name pxa_lubbock, mach_init addr 0x8060680
uart_mod:0, desc_in:, desc_out:, converter:
SKYEYE: use xscale mmu ops
start addr is set to 0xa0000000 by exec file.

=======================================

but when the configuration is:
cpu: pxa27x
mach: pxa_mainstone

it stops at:
==============
arch: arm
cpu info: xscale, pxa27x, 69054110, fffffff0, 2
mach info: name pxa_mainstone, mach_init addr 0x80610c0

(stop here)
=================================================

what could be the cause of it?

thanks for any suggestions.
