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
