Hi all,
I am working on a mpc860 hardware derived from the viper board and I use a
debugger to
step through the code. I have flashed a redboot image on the board. Then I
loaded a simple
application via SMC1 into the RAM.
Now, when I try to start the application with the go command, the system
hangs.
The problem occurs in the function hal_thread_load_context() during the
processing of the
macro hal_cpu_int_merge. The external and decrementer interrupt bit in the MSR
Reg. will
be enabled here. After the external interrupt is enabled and I perform a single
step with the
debugger the system starts running and I am not able to stop or break. All
interrupts except
the SMC1 are masked at this point.
If the EE-bit in the MSR Reg. is not enabled here, the example application
starts und runs.
Unfortunately, as long as the EE-bit is not set, cyg_thread_delay() ,,,,
doesn't work. Can
anyone help to solve this problem.
Thanks and Regards
Georg Brutscheid
