Trying to upgrade my 4.6.2 MPC860 based BSP to the last RTEMS, I took the
mbx8xx BSP and incorporated my changes.
The CPU fails on SW emulation exception at the last moment, when
rtems_initialize_executive_late performs context switch to Init task:
The execution of mtmsr is OK (abatron BDI-2000 debugger), but next single-step
assembler instruction "isync" causes "SW emulation exception" and program
counter has a very strange value in the middle of the RAM (although I expected
it to be 0x1000 in the case of SW emul.exception).No caches are switched on at
Does somebody have a guess why CPU behaves so strangely?
If no, can somebody acknowledge that mbx8xx BSP really runs with RTEMS 4.8.0,
Thanks a lot.
