Power monitoring on Jetson TX1

Autonomous Machines Jetson & Embedded Systems Jetson TX1

I have just flashed the latest jetPack version available in the nvidia website and all has worked well, however, now I am interested in monitoring the power consumption of the device. It is possible?

I have searched in the schematics of the Jetson TX-1 and apparently, there are 3 power monitoring devices (TI INA3221) connected through I2C at 7’40, 7’h42 and 7’h43, but in /sys/bus/i2c/devices, I can only find the 0x42 and 0x43.

I am interested in reading from the 0x40, which monitors the CPU and GPU. It is not supported yet?

Dear Ying27,

Were you able to resolve your issue? I am facing the same issue.

Doesn’t look like this is possible on the board itself: [url]https://devtalk.nvidia.com/default/topic/935115/jetson-tx1/soc-power-monitoring/[/url]

Newer revisions of the TX1 module enable the use of INA power monitors, see [url]Jetson TX1 - INA226 (Power Monitor with i2C Interface) - Jetson TX1 - NVIDIA Developer Forums
