Hi Matthew,
Do you have access to the shell on a serial or telnet console?
The RTEMS shell has a "task" command that shows the state of all the
tasks running in your system:
MNTB [/] # task
ID NAME SHED PRI STATE MODES EVENTS WAITINFO
------------------------------------------------------------------------------
0a010001 USBd UPD 200 TIME P:T:nA NONE
0a010003 ERRM UPD 55 MSG P:T:nA NONE 22010003
0a010004 ADLT UPD 92 MSG P:T:nA NONE 22010006
Based on the wait info, you can work out what it is waiting on using the
other shell commands, such as:
queue or sema
MNTB [/] # queue
ID NAME ATTRIBUTES PEND MAXPEND MAXSIZE
------------------------------------------------------------------------------
22010001 USBr DEFAULT 0 3000 1
22010002 USBt DEFAULT 40 10000 1
22010003 EMIQ PR 0 15 32
In the example above, the task ERRM is waiting for a message on the
queue EMIQ.
If you do not have access to the shell, you can try to follow through
what the shell actually does in the code, and hopefully it will provide
the information that you are looking for.
regards,
Ian Caddy

What's the best way to determine the status of a task? Is there an
API to determine if its pending or a runnable state? Is there an API
to determine what its pending on? I'm trying to determine what some
tasks stopped executing and I can't use a debugger. Preferably, can
somebody point me to a symbol that I can peek?
