Thermal Service Failure

anurag16doshi — Mon, 18 Jan 2021 09:27:52 GMT

We are working on iMX8M nano chipset. We have ported android 10 on imx8M nano evk and is working fine. But, when we port same build on our custom hardware, we are getting some debugs related to 'vendor.thermal-hal-2-0' service as shown below. The difference between evk and custom hardware is that the EVK has 4 cores and custom board has single core. What could be the reason for thermal service failure.

here are the logs for the same. Please guide us to identify the issue .

[ 1371.530462] init: Received control message 'interface_start' for 'android.hardware.thermal@1.0::IThermal/default' from pid: 238 (/system/bin/hwservicemanager)

Thanks in Advance.

Hi anurag16doshi

for single core one can try "maxcpus=1" boot parameter as in example

Thank you it worked as we have a single A53 core variant of chip-set.

Also, we want to flash Android images (.img) on to eMMC from SD card, whats the procedure for that ??

Thanks in advance.
