Power and thermal management support on i.MX8M Mini

[namanthaker]

Hello,

I am looking into power and thermal management techniques supported on i.MX8M Mini boards and need some help to confirm a few things.

I am refering below image to get information about the thermal and power management techniques supported on i.MX boards. The image is from thermal and power management document for i.MX6 boards. Since there is no such document for i.MX8, I am refering to i.MX6 document.

Board Details:
SoM: i.MX8M Mini
BSP Release: imx-yocto-L5.4.24_2.1.0

From the above image, could someone please help confirm which of the algorithms are already implemented and running in the BSP?
For the ones which are not supported yet, please provide more details on how their support can be added in the SW and the dependencies to get them running.

Regards,
Naman

Hello @Rita_Wang ,

Thank you getting back to me.

I am unable to download the document from the 1st link. Could you maybe help to share the actual document in pdf or some other form? Or let me know which document is it so I can search for it over NXP site.

The second document is the one I am already referring.

Naman
