AM620-Q1: AM620-Q1 MCU SDK migration 10 to 11

Tool/software:

Hello,

I'm encountering difficulties while migrating from version 10 to version 11 of the MCU SDK for the AM62x.

In our platform setup, we run all four A53 cores in SMP mode. However, I’ve noticed that version 11 appears to have shifted to AMP mode by default.

What’s the recommended approach to preserve the previous SMP configuration or achieve similar behavior in the new SDK, ideally without major architectural changes?

Hi Wojciech Jaśko,

I am a bit confused here, could you clarify if you were using Freertos SMP mode in AM62x SDK version 10.0 by porting the SMP kernel on your own, because AM62x MCU+SDK doesn't support Freertos SMP mode out of the box, SMP mode is not supported in version 11.0 and it was not added in version 10.0 as well. AM62x MCU+SDK only supports Freertos AMP mode which was added in version 10.01, please refer to the release notes: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/11_00_00_16/exports/docs/api_guide_am62x/RELEASE_NOTES_10_01_00_PAGE.html

Best Regards,

Meet.

Hello Meet,

Thanks for a fast reply. In version 10, generated files from a sysconfig supported SMP mode - there were checks for the core ID. This part was removed in SDK 11.

Hi Wojciech Jaśko,
I suppose you are mentioning the following check:

This does not indicate that SMP mode is supported, let me try to further check why this was removed from the newer version, but please note that this core ID check doesn't indicate that SMP mode was supported in version 10.0

Best Regards,

Meet.
