I want to run some tests how low I can get the power consumption on the Radxa Zero. My goal would be to power it from a 500mA USB 2.0 port (2.5W), ideally even with Wifi. In my application I don’t need HDMI and GPU.
*How can I disable cores. I assume maxcpus=1 would do the trick?
*How can I limit the max frequency of the cores?
*Is there a way to limit the power consumption of the GPU? (Maybe this is even not necessary if the GPU automatically enters a very low power mode when unused)
*Can the HDMI be disabled?
*Any other ideas to limit the power consumption are welcome of course
Thanks a lot for your help! Can’t wait to run the first power measurements.
