Questions about OS_TimerSet

[yuanshuaipeng-sakura]

In SCH APP, the function SCH_MinorFrameCallback uses OS_TimerSet, but OS_TimerSet specifies that it cannot be used in the callback function of timer, and SCH_MinorFrameCallback is the callback function of timer. What is the purpose of this design? I tried to run this scenario, and calling OS_TimerSet from SCH_MinorFrameCallback failed, returning -35.

I have now run into the same problem; when a CPU is configured as a CFE Time client but isn't getting major frame interrupts, the scheduler stops running because of this issue (the timer isn't reset). The system basically halts. @yuanshuaipeng-sakura, did you find any sort of resolution?

I changed the relationship between SCH_MinorFrameCallback and the timer interrupt to asynchronous by using threads and signals. However, this application still has other bugs, one of which is a very hidden multithreading safety issue that occurs with an extremely low probability and can lead to a segmentation fault.This project seems to be no longer maintained, we can discuss it on another platform if you’re interested.

Thank you for replying; I'm not currently interested in pursuing a fix further (I tried and failed with the constraints I had). Good luck in your efforts, I wish you success!
