Part Number: TMS320F28379D

HI everyone

I use matlab 2022a. test on F28379D Launchpad

I use CLA task trigger source for epwm1 for toggle led, it's ok

but when i use C28x_Hardware_Interrupt block trigger epwm6 interrupt, cla_subsystem not operation, led not toggle.

i remove the interrupt vector of epwm6 cla_subsystem operation, led toggle.

when i use matlab 2021a i can use CLA and epwm interrupt. How to fix this issue

Hi Dang,

Looks like it is a bug in the TI C2000 support package as the Epwmx interrupt is not cleared once the ISR is serviced.

We will work on this issue to fix it at the earliest. But meanwhile, you may use the custom code approach as a workaround to clear the Epwmx interrupt.

This can be done by using system outputs block inside CLA_Task_1 with the below mentioned code:

EALLOW;

EPwm1Regs.ETCLR.bit.INT = 1;

EDIS;

Please let us know if this workaround has resolved the issue and Thank you for bringing the issue to our notice.

Best Regards,

Ram Alla
