Did anyone try any ways to decrease (idle) power usage? I tried with the proposed armbian image (6.1.84) and when idle, it draws ~4W.
I don’t use lots of the peripherals (GPU, Audio codec, NPU etc.) … Is there a way I can disable those power domains to decrease energy usage? I tried to disable them in the DTS but couldn’t get the idle 4W to decrease.
Powertop shows a lot of 100% usage in device stats, e.g.
Usage Device name
100.0% runtime-fd7c08c0.aclk_rkvenc1_pre
100.0% runtime-fde80000.hdmi
100.0% runtime-fd7c08a0.aclk_rkvdec0_pre
100.0% runtime-fd7c08b0.aclk_jpeg_decoder_pre
100.0% runtime-fddf0000.i2s
...
although they are not in use.
When fully suspended to RAM, the board draws ~1W.
It’d be awesome if we could disable unused peripherals/CPU cores to get between 1-4W power consumption.
