Hailo-8 fixed System's clock speed option

General Discussion

Hi,*
*
while running the inferencing on Hailo-8, I am keep on getting the following warning message. It shows there is temeperature increase and continuous toggling of system clock between 400MHZ ←> 300MHz.*

[HailoRT] [warning] Got health monitor notification - temperature reached orange zone. sensor id=0, TS00=103.98878c, TS01=103.634674c*

[HailoRT] [warning] Got health monitor notification - System’s clock has been changed from 400000000 to 350000000

[HailoRT] [warning] Got health monitor notification - System’s clock has been changed from 350000000 to 400000000

I would like to check if there is some option to keep it fixed on lower number to avoid this toggling. From hailortcli, I didn’t find any option. Firmware version is given below

hailortcli fw-control identify

Hi @user1245,

The toggling is normal thermal throttling - your chip hit ~104 °C (Orange Zone), so the firmware drops the clock to cool down, then restores it. There’s no runtime flag; you set a fixed cap via persistent firmware config.

Supported values are only 100, 200, or 400 MHz (not 350). To cap it lower:

hailortcli fw-config read --output-file config.json

Edit the system section:

{ "system": { "name": "Hailo-8", "max_neural_network_core_clock_rate": "200MHZ" } }

Then:

hailortcli fw-config write config.json

Then power-cycle the device.

Note: 104 °C means under-cooling. Capping the clock helps, but the real fix is better cooling (heatsink/airflow). Don’t disable throttling - it’s protecting the chip.

Thanks,

Thanks Michael.

I am getting the following error -

It looks like you have a Hailo-8 module from Advantech.

Changing these settings requires an EEPROM connected to the Hailo-8. The EEPROM is optional, and Advantech may have chosen not to populate it. If the EEPROM is not present, you will not be able to store or modify user configuration settings.

This warning does not necessarily mean the EEPROM is missing. It can also occur when the device supports user configuration but no user configuration has been written yet. This is typically the case on new Hailo M.2 modules from Hailo.

I would recommend attempting to write a user configuration. If the write operation succeeds, the warning should disappear afterward. If the write operation fails, contact Advantech to confirm whether the EEPROM is populated on your specific hardware.

I applied it

hailortcli fw-config write config.json
Executing on device: 0001:01:00.0
root@OpenWrt:~# cat config.json
{ “system”: { “name”: “Hailo-8”, “max_neural_network_core_clock_rate”: “200MHZ” } }
root@OpenWrt:~#

but still receving the message looks like it didn’t work although there is no error while writing.
