I need to disable Audio Processing Engine (APE) block (ADSP Cortex-A9 on TX1) to save power.
Possible?

Thanks

ADSP block only needs about 3~4 mW in idle status, do you really need it to be disabled?

Is there a clock I can check to make sure whole APE is scaled down and not used/initialized by Linux audio subsystem? 4mV is good, if it is for whole APE.

It is internal clock, can not be detected outside.

Where is ADSP FW gets loaded?

Hello, DmitriK:
At this point, we do not support ADSP on L4T.

Hi, I know this post is a little bit old but is the ADSP supported now? I would like to run a echo cancelling algorithm on it.
