Measuring power consumption on Hailo8L with RP5 (AI KIT)

[rybalkin]

Hi to All,

I cannot measure power consumption on Hailo8L RP 5 (AI KIT). The driver and the runtime are all 4.19. I have checked similar posts with the same problem but none of them suggested a solution.

When I use command (hailortcli measure-power) proposed in the following post:

Reproducing Power Benchmarks

Hi! I’m looking forward to purchasing a few of the starter kits! A couple of newbie questions: -I’d like to know if and how I can reproduce the power benchmarks using the starter kit. I’m referring to the power benchmarks shown on this page - AI Benchmarks: Evaluating Hailo 8 Accelerator Performance. Are there are power benchmarks for the starter kits than are significantly different than the ones shown on that page? -That page indicates that you acquired the benchmarks using an Intel i5 h…

I observe the following output:

How to measure the power and temp of Hailo-8 M.2 async

There is a simple Python API to read-out the data from the temperature and power sensors. This can be executed async from any other activity on the device. #!/usr/bin/env python3 import time from hailo_platform import Device def _run_periodic(delay=1): device_infos = Device.scan() targets = [Device(di) for di in device_infos] for i, target in enumerate(targets): target.control.stop_power_measurement() target.control.set_power_measurement() target.control.st…

The above exception was the direct cause of the following exception:

When I use the following code proposed in the same post

from hailo_platform import Device

dev = Device()

dev.control.get_extended_device_information()

My output includes:

Current monitoring: Disabled

The output of the following command:

find /usr/ | grep libhailort

is:

/usr/lib/libhailort.so

/usr/lib/libhailort.so.4.19.0

Any help will the issue will be appreciated!

Thank you and best regards!

The answer is in the follwing post:

How to measure the power and temp of Hailo-8 M.2 async

H i to All, I support the question about the current monitoring being disabls on Hailo8l on RP5. I also have “Current Monitoring: Disabled” I see the following output when attempt measuring power: [HailoRT] [error] Firmware control has failed. Major status: 0x400300b4, Minor status: 0x400300b4 [HailoRT] [error] Firmware major status: CONTROL_PROTOCOL_STATUS_UNSUPPORTED_DEVICE [HailoRT] [error] Firmware minor status: CONTROL_PROTOCOL_STATUS_UNSUPPORTED_DEVICE [HailoRT] [error] Opcode HAILO…

In short, the AI KIT does not have the required component to measure power consumption.
