Dear experts

For R5F lock-step error detection logic, it mentioned that CPU Output Compare Block mode(operating mode, Self Test Mode, Compare Match Mode,…).

Are there any software to support these features to deliver to customer?

thanks a lot!

Dear Akash.

Thanks for your reply. the ticket is about how to enable lockstep mode.

The origin question is to ask if TI provides the SW to support CPU Output Compare Block mode(such as operating mode, Self Test Mode, Compare Match Mode,…), see chapter 6.3.3.5.1 in DRA821 TRM.

Would you please help double check this question?

thanks a lot!

Hi Yong,

I think output will go to the ESM module and ESM module can generate the interrupt that would be processed by core to take appropriate actions.

I really doubt there is reference example, will check and get back to you.
