I am porting a PXA255 platform from CE.NET 4.1 to 5.0, the image I built
always halts even before OEMInit is called. I finally figured out it halts
at the line 584 of
C:\WINCE500\PRIVATE\WINCEOS\COREOS\NK\KERNEL\ARM\armtrap.s, which is
attached below.

mtc15 r1, c1 ; enable the MMU & Caches ;

It looks like a memory related problem, this platform has 128MB DRAM
onboard with 2 64MB chips. Maybe I am just missing something in memory
configuration that is required by 5.0?

I then tried to port this platform from 4.1 to 4.2, I was able to port it
fairly easily without modifying anything DRAM related and the 4.2 image
works just fine. Does anyone have experience about this kind of problem? Any
comment and suggestions are welcome!

Nothing has changed in this regard, check your cache code.
