Hi @Shreejit_Paul!
Is this ticket related to this same issue?
Regarding your doubt, the approach used for HMP in our modules is through device tree overlays. For the Colibri iMX8X, we have an overlay called colibri-imx8x_hmp_overlay.dts that you can enable by following the steps described here.
Just out of curiosity, if you want to check what is written in the .dts file, you can use our Git. For this specific one, check here.
Best regards.
