Tool/software:TI-RTOS
Hello,
We are running a real time application on the DSP using clock timer triggered every 300 micro-second. We have observed an important delay in the trigger, up to 5 milli-second. So our real time is completely out of sync causing major issue as you can imagine.
This happens more frequently when we using the UART intensively but does not seems related. I instrumented uartIsr() in the sysbios and did not see any unusual activity there. Also went to instrument EventCombiner_dispatch() ... nothing there neither. Yet they are both being blocked.
We are starting to think that the issue could be related to the syslink. Indeed we also see the same timing problem on the ARM side. Have you heard of anything similar ? Do you recommend a place part of the syslink code I should measure the execution time ?
Thank you,
Cheers,
Vincent
