Hello~^^
I work for Delta Tau
Thank you for your help everytime
I have a question
The situation is like this.
The customer is using the powerpmac cpu board.
(firmware version : 2.1.1.3)
It was operating normally for several months.
Suddenly the machine stops running with Sys.WDTFault=1
The RDY LED on the front of the CPU board has turned off.
The following logs were sent to the debug serial.
Xenomai: Posix: closing semaphore "PPMACPLCCSem0".
Xenomai: Posix: closing semaphore "PPMACUserSem1".
Xenomai: Posix: closing semaphore "PPMACPLCCSem1".
Xenomai: Posix: closing semaphore "PPMACUserSem2".
Xenomai: Posix: closing semaphore "PPMACPLCCSem2".
...~~...
Xenomai: Posix: closing semaphore "PPMACUserSem30".
Xenomai: Posix: closing semaphore "PPMACPLCCSem30".
Xenomai: Posix: closing semaphore "PPMACUserSem31".
Xenomai: Posix: closing semaphore "PPMACPLCCSem31".
Xenomai: Posix: closing semaphore "PPMACRtiSem".
Xenomai: Posix: closing semaphore "PPMACRtiIntrSem".
Xenomai: Posix: closing semaphore "PPMACFuncLoad".
Xenomai: Posix: closing semaphore "PPMACFuncUnload".
Xenomai: Posix: closing semaphore "PPMACStartIoctl".
Xenomai: Posix: closing semaphore "PPMACFinishIoctl".
Xenomai: Posix: closing semaphore "PPMACBKGStart".
This is all I have checked from the customer.
My opinion is
Perhaps gppmac seems to have stopped.
I have a question
1) What are the conditions under which this situation can occur?
(Sys.WDTFault==1, RDY LED Turn Off, Debug Message Occur )
2) Is there an expected cause?
3) What variables are there to check for the cause?
4) Are there any variables that I can monitor ?
5) What are some things I need to check to determine the cause?
6) Do you have any advice on this situation?
Thank you for your help everytime
Best regards
