TMS320F280049C: ISR sometimes not getting called

abraham mathew

Hi:

I have a C28x Interrupt block being used to call two seperate tasks in simulink (1 for the CLA, and other for some PWM items).

- My CPU interrupt numbers are [1 11], PIE interrupt numbers are [1 1], simulink task priorities are [30 20] and both tasks non-preemptable.

- In the PIE table, 1,1 is for ADC interrupt, 11,1 is for CLA interrupt.

- What im seeing is that on some code builds i am seeing the stuff in those functions being run and other builds i am not seeing it being run (even though i see the calls for those tasks in the generated code).

Is there something that might cause this behavior? Im using Matlab R2020b for code generation.

Appreciate the help.

Thanks,

Abe

Hi,

Please take a look at MathWorks FAQ at this link below:

If you have further questions, the best way to get support on MathWorks products is to contact MathWorks live tech support.

You can also search for answers or post a question on MATLAB Answers C2000 forum. Additionally, there is info on MathWorks support C2000 in Documentation and Examples.

I will close the thread from here as the software is supported by MathWorks team on their forum.

Thanks & Regards,

Santosh
