I have propably found a solution. There is the cogent board csb226 with ucos
port. In this port the MMU is set to see the exception vector area at
0xa0000000 (the beginning of the ram area). I have found only documentation
without source code. Could you help me how to set mmu in such way? I tryed
to find source code example but I couldn't.
Regards
Jacek

Hi all,
could help me to understand how to relocate interrupts on the pxa255
processors?
The arm architecture has the interrupt vector at 0x0 or 0xFFFF0000 address.
How
to place the interrupt vector in the SDRAM memory while this procesor has
the SDRAM memory
placed at 0xa0000000. I tryed to understand the uboot start code and other
loaders but they have the interrupt vector placed at a flash.
I'll be gratefull for help.
Jacek
