Hello TI Team,

Please clarify with below question on the errata MSS#61.

Reference: "AWR294x Device Errata Silicon Revisions 1.0, 2.0" / "SWRZ102B – NOVEMBER 2021 – REVISED OCTOBER 2023"

MSS#61 states " Data aborts seen while access made to last 24 bytes of the configured MPU region and cache is enabled."

1) Is this issue only for MSS?

2) Can similar issue occur with DSS Cache configuration?

Thanks,

Hello BC,

WE had seen this issue only with the MSS cache configuration. Not in DSS anytime.

Hello Saswat,

But can you positively confirm with an example that this is working in DSS?

Thanks,

Hello Manjunath,

This issue has never been seen on the DSP for us.
If you are very doubtful about this errata, I would suggest you can try it out as well on your end.
In our test cases we have never had any issues with the DSS. While this errata was being evaluated, the feedback I got was that DSS was a not a candidate for this.
Still if you are unsure, I would suggest you to test it out.

Regards,
Saswat Kumar
