How to disable the DVFS function for i.MX6Q

[yuuki]

Dear all,

We run AndoridKK4.4.3 BSP on the i.MX6Q-SABRE-SDB board.

However, we have the problem that a system reboots.

When a frequency is fixed to 396MHz, it seems that the problem does not occur.

At this time, We observed the voltage of VDD_ARM_IN and VDD_ARM_CAP.
However, the voltage is stable.

We want to try disabling DVFS function.

Would you tell me the method to disable the DVFS function?

Best Regards,
Yuuki

You can try this command
# echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
to disable DVFS.

Have a great day,
Victor
