PROCESSOR-SDK-AM62A: Read ECAP Registers from MCU

Hello Joseph,

Joseph Tingin said:

I'd like to read the Main domain ECAP registers from the MCU domain. I understand from the previous thread that I may need to set up the RAT for this due to cross domain memory accessing. Is this the case?

Yes, your understanding is correct .

Joseph Tingin said:

Are there any additional steps needed to access these registers? Does the ECAP instance have to be setup in the Main or the MCU domain?

Yes except RAT you  don't need to do any other steps for accessing the ECAP registers from MCU core.

I assume that your application needs to monitor ECAP events from MCU core and not in MAIN domain. In this case, you can set up the initiations in MAIN domain and just read ECAP events from MCU core.

Also, it seems the latest AM62A Rev B TRM is missing information about some of the registers like ECCTL. Can you please share the details on the missing ECAP registers?

Yes, I can check with an internal Team. Meanwhile, I have an older version of AM62A in which registers information   are there and you can use it.
