there is no INA238 i2c device in Thor devkit.

What does it means of oc3_event_cnt? Does it include below three situation.
Average VDD_GPU power: 100 watts
Instantaneous VDD_GPU power: 120 watts
Instantaneous (VDD_GPU + VDD_CPU_SOC_MSS) power: 144 watts

looks like curr4_input is the INA238 read current, and it’s module VIN power. Is it correct?

When your instantaneous power over a specific condition, it will trigger OC3 and do the throttling.
thanks Wayne.
Could you check the question there is no INA238 i2c device in Thor devkit.
There is always INA device on Thor devkit to measure the power … not quite sure about what is your question here.
he is telling it is not listing in /dev/i2c* devices list
also
/sys/bus/i2c/devices/2-0044/hwmon/hwmon*/
the online document said:
- INA238:
/sys/bus/i2c/devices/2-0044/hwmon/hwmon*/
but can’t find it.

Which Jetpack version are you using? I have this one on my side.

There is no update from you for a period, assuming this is not an issue anymore.
Hence, we are closing this topic. If need further support, please open a new one.
Thanks ~1105
Is this still an issue to support? Any result can be shared?
