Software watchdog fault, didn`t work power pmac

[PillowPark]

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

The serial port log shown is normal release of semaphores when a gpascii thread closes. It does appear though, that you have "crash" of some kind as the "Ready" LED goes out. This is a technical support issue. Please contact the ODT Technical Support Group at support@deltatau.com.
