Problem with Virtex II Pro PowerPC 405 in 'hal_cpu_int_merge'


Hi all!

I have the same problem described here

http://ecos.sourceware.org/ml/ecos-discuss/2004-01/msg00080.html

I am working with an adaption of the Mind port of eCos for the Virtex II Pro on an own developed hardware. I am building a ROM startup configuration and don't use Redboot. I debug with GDB over a JTAG connection.

I read the mail above and also disabled the MMU and Data/Instruction caches. That brought no effect.
I also unchecked the 'use seperate interrupt stack'...


The instruction where the stack crashes:

	.macro	hal_cpu_int_merge sr
        mfmsr   r0
        rlwimi  r0,\sr,0,16,16
        sync
        mtmsr   r0
        sync
	.endm

 at the mtmsr r0.
 the content of r0 at runtime is 0x9000

I have no idea why!
Who knows shomething about this problem.?

For more informations about hardware or something else, write me a mail!

Thx for help
Stefan
