Hello,

 

I encounter a weird problem with my custom imx6ul board.

The system boot normally (we are using Buildroot based solution) but hangs EXACTLY in 600 seconds after the OS takes its control.

U-Boot does not have such behaviour, it lasts until reset or power off.

 

I tried to rebuild Linux kernel in different ways, clocks, idle, power modes but there is no effect on it. 

Don't think it's a kind of HW issues, all power rails looks stable, clocks are preset.

 

Any ideas?

 

Thank you
