i.MX 8M power management related freeze

Hi,

I'm running yocto on an sd card in the Google Coral platform.

We are developing a program that works fine otherwise, but after running for a few minutes the display that is connected to the coral shows a couple of kernel messages and the entire system freezes until power is cut by unplugging the system.

The kernel messages that appear are either of the following:

 

#1:
buck3: failed to disable
imx8m_gpc_pm_domain gpc_power_domain@4: failed to power off the reg-110

#2:
buck3: failed to disable
cpu cpu0: failed to scale dc_reg up: -11
imx8m_gpc_pm_domain gpc_power_domain@4 : failed to power off the reg-11
cpufreq: __target_index: Failed to change cpu frequency: -11

 

Could this be related to having not set some kernel flags?

Hi Milan

 

from log "cpufreq: __target_index: Failed to change cpu frequency" issue may be related

to cpufreq driver so one can check sect.2.5.3 CPU Frequency Scaling (CPUFREQ)

i.MX Linux Reference Manual​

Also issue may be posted on coral support  https://coral.ai/software/

 

Best regards
igor
