AM5716: ABB mode in OPP High

Keith Elliott

Part Number: AM5716

I'd like to follow up on the following forum post, e2e.ti.com/.../2169097, which has been locked against further comment. It's seems like the new AM57xx PDK (version 1.0.7) has added support for the ABB enabling code. Can someone please confirm this?

Keith,

Sorry for the delay in getting back to you on this issue. Yes, I confirm that ABB has been enabled in the SBL in Processor SDK RTOS 4.0 and later versions. You can check the bug ID PRSDK-2344 in fixed issues section here:
processors.wiki.ti.com/index.php

Hope this helps.

Regards,
Rahul

The SBL changes can be located at pdk_am57xx_1_0_8\packages\ti\boot\sbl\board\src\sbl_avs_config.c. If you search for the variable pmOpp in that file, you should be able to locate all the changes that were made to enable this feature.

Note, the SBL uses Power Management(PM) LLD APIs to setup the AVS and ABB so there is additional dependency of including PM LLD headers and library in the build.

Hope this helps

Regards,
Rahul
