Hi,

I'm using a project with TI-RTOS with TIVAC129 xnczad.

I have the necessity to disable the exception Handling because I have a time critical application.

Could you provide an example on how to do that?

I know the FAULTMASK register is used for that, but you have to access in privilege mode.

Thanks in advance,

TI-RTOS applications run in privilege mode so you should be able to manipulate FAULTMASK in your code.

Additionally, Hwi_disable()/Hwi_restore() can be used to surround critical section code.
These APIs will disable all interrupts managed by dispatcher that haven't been configured as "Zero Latency" interrupts.
