NANOPI_NEO VDD_CPUX Control GPIO not set

Hi,

 

After installing latest version of Armbian 5.59 Stretch, I found that CPU temperature was shooting up too high, and I figured out that the GPIOL6 controlling the VDD_CPUX between 1.1V and 1.3V is not set properly as a result the Pullup resistor R455 is holding the FET gate always high and it is always running by default at 1.3V, even though scaling_max_freq was set 912MHz.

 

After manually switching the GPIO to OUTPUT_LOW the temperatures aren't going that high anymore.

Just thought the DEVs should know.

 

Thanks
