TMS320F28374S: nest interrupt doesnot work

Hi Jane,

I am not a bios sys expert. I can see what issue you have with the interrupt module

jane huang said:

will bios/sys effect the result?

I am not completely sure what the issue is- are you able to run to the nested interrupt ISR - adc_isr ?

jane huang said:

it can run for a short while ,and stopped at 0x3fe2ed

What do you mean by nest is not enabled and when you say isr can run normallly- do they nest like you want ?

jane huang said:

if the nest is not written, adc_isr and adc_isr_fast can run normally

Thanks

thanks for your answer.

I should try to make it clear

We use sys/Bios ，and  we want to have the interrupt nesting.  we program the nesting interrupt as mentioned above. but it can not runing Continuously, but jump to  0x3fe2ed, and stopped.

can you help to realize the nesting interrupt?

thanks

Hi Jane,

Did you try if you don't use sys/bios can you do interrupt nesting normally ?

Thanks
