hi all, i'm working on porting some drivers to QNX and have run into a bit of a hiccup.  The hardware i want to run 
on(Actis XCOM-9460) utilizes the PPC460GT and is similar to the AMCC460GT EVK and as such i have purchased one as a test
 system to get QNX working.  As it stands i have managed to compile and boot into QNX on the AMCC evaluation board, 
however when i attempt to boot into my Actis board it crashes every time.

the command sequence i use is just:
tftpboot 200000 /bsp-amcc-ppc460gt.ifs -- to load the image into ddr
go 200000 -- to execute the image

-------- the result of this action(from the Actis board) is attached below:

Program Check Exception

-----------------------------------

The most likely case i can see is that it is a memory issue ( as the evaluation board is using DDR1 and the Actis board 
is using DDR2 ) because both have ddr mapped 0x00000000-0x7fffffff, although any ideas or suggestions would be greatly 
appreciated
