Hi all,
I'm doing a port of redboot for a board with a powerPC MPC860.
When I execute redboot in RAM, I have a software emulation exception
(0x01000) on the line 291 of packages/hal/powerpc/arch/current/src/vector.S
: mtspr TBL_W,r3 (TBL_W=284)
With my debugger (gdb), I see this instruction: [mttbl r3] instead of [mtspr
TBL_W,r3] (this is correct) and I have the following message:
Program received signal SIGSTOP, Stopped (signal)
Any idea?
Nicolas
