CCS/TMS320F28377D: Interrupt only firing once

Dan Ratfeld

Tool/software: Code Composer Studio

I am attempting to perform some processing using the CLA on my Delfino processor. After looking at cla_asin example, I tried making a simple program that calls Cla1ForceTask3() to see if I could make it run.

This much worked fine, the first time. However, I have it on a timer to redo this every few seconds, but this only happens the 1st time. After that no subsequent tasks occur.

All I see in the example mentioned above is to use PieCtrlRegs.PIEACK.all = M_INT11; to make sure the interrupt is cleared at the end of the task, however even when doing that I don't see any behavior beyond the first run. Is there anything else I need to do to prepare the CLA for the next time it is called?

Hi,

I am assuming that you are calling the CLA task inside timer ISR. If yes, then please check if timer interrupt is happening IInd time. PieCtrlRegs.PIEACK.all = M_INT11; code is fro enabling the CLA interrupt to CPU at the end of task which will be generated only is CLA task has been started.
