Jetson nano JetPack4.5 Soctherm: OC ALARM 0x00000001

How to modify the value from the software to change the current value of the undervoltage protection?

hello 18272077327,

may I know what’s your actual use-case?
please also refer to Thermal Zone session, software using trip points to communicate with thermal zones.
please have your thermal solution; if the temperature still increase, there’ll be software throttling to reduce the clock rate for cooldown, and hardware throttling to shutdown the device.

I used the nano development kit. I installed a fan for heat dissipation. Previously, the kit was released in nx by modifying echo 5000> /sys/devices/c250000.i2c/i2c-7/7-0040/iio:device0/crit_current_limit_0, But nano does not have this path?

hello 18272077327,

INA3221 power monitor can be read using sysfs nodes, i.e. /sys/bus/i2c/drivers/ina3221x/6-0040/iio:device0/
may I also which Nano platform you’re using? Jetson Nano 2GB does not have an INA3221 power monitor.

I checked /sys/bus/i2c/drivers/ina3221x/6-0040/iio:device0/crit_current_limit_0 with a value of 32760ma. This value is very large. Why does it cause an overcurrent protection alert?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

hello 18272077327,

may I know what’s the actual use-case, how you reproduce this failure.
please share the complete steps for reference, thanks
