TMS320F28377D: Xint - CLA problems

Andrea Gaudi

Hello,

I have a problem using the 28377D microcontroller (single core configuration):

I'm using task1 of the CLA that is triggered by ADC EOC. I have also XINT1 enabled. When the XINT1 interrupt occurs my CLA task stop running forever and I cannot understand why. Any ideas?

Thank you very much,

Andrea

Hi Andrea,

How do you conclude this behavior. Is it because CLA end of task interrupt to CPU is not getting executed? If yes, could it be possible that XINT1 ISR is masking this interrupt?

Hi Vivek,

I toggle a GPIO in the CLA task and also in the XINT. When the XINT happens i see that the GPIO toggled by the CLA remains fixed. Could it be possible that the XINT routine use to much time and, for some reasons, the CLA stops?

Thank you very much,

Andrea

Andrea,

Sorry for late reply. It'll be helpful if you can share the code for both routines to see how GPIOs are getting toggled.
