i.MX6 fails to restart from linux reboot command

Hello all,

 

From the kernel console when I type "reboot", sometimes restart will fail in the middle of u-boot message.

When I set the cpufreq governor to "userspace" and frequency to 792Mhz, it will not fail.

But setting the frequency to 396Mhz will most fail.

Is there somehow a failure during startup if cpu is not maximum frequency or PMIC is not on maximum voltage?

I can make it always be at 792Mhz before start, but I am wondering what would be the reason behind failing to restart.

 

Best Regards,

Yuri
