TMS320F280039: Flash API kills all interrupt

Jack Tan80

Part Number: TMS320F280039

Dear C2000 expert,

From flash api user guide, it mentions that flash api execution can be interruptible.

But my ISR is killed when calling flash api function, I'm pretty sure that all my ISR function is executed in RAM to have better execution performance, and ISR is recovered while flash api execution finished.

Can you share some comments about this?

Regards,

Jack

Hi Jack,

Flash API does not disable any interrupts.

How did you confirm that the ISR functions are executing from RAM and not flash?

Thanks and regards,

Hi Jack,

I did not hear back from you.

Do you need further support on this post? Or can I close this post?

Thanks and regards,

Sorry for delayed response. This is resolved by put flash api to another bank.

Hi Jack,

Yes, you can't execute flash API or the ISRs from the same bank on which flash erase/program operations are targeted.

Thanks and regards,
