Your gpio pinout guide was most helpful

I do get kernel messages if I use the serial debug port (RX – middle one) as GPIO 5 for the LED pin, but it does not always finish booting up with login prompt. (unstable for some reason) I have disabled the serial console and enabled pwm in the fex file

I also currently cant get PWM screen brightness to work on this GPIO 5 either like with a Raspberry Pi

When I use GPIO 7 i mostly only see the login prompt

Where did you buy your screen ?

My 320×480 screen does not work correctly either (only part of screen shows)
