Hi Joel / All,

I would like to make use of these macro's as I am chasing down a
difficult to find uart bug.

However, I am doing something wrong as I can not get them to work for
me.

I am using RTEMS 4.6.5 on Coldfire.

Gdb version is 6.0

It appears that gdb does not understand the definition of  the 
Thread_Control structure.

Any attempt to cast a pointer in gdb fails with the same
message.

Any suggests as to what I can do to fix this?

Regards

Paul.


Example output:

(gdb) rtems_check_state
RTEMS System State is:
     $5 = SYSTEM_STATE_UP
NOT inside dispatching critical section
NOT inside an ISR
