verify your mapping pins gpio with :
$> gpio readall
PS: need install WiringOP

And? What next step?

Hi ! I have the same problem.
Is there any progress with the LED matrix? I think what need to start with a file framebuffer-internal.h There are described used GPIO

rpi-rgb-led-matrix doesn't use WiringPi.
Address of GPIO operation is being done by itself.
Substantial correction is needed.

If you rewrite this cord, it may work only a little.

Because they seem to use hardware PWM.
GPIO of H3 board doesn't have the hardware PWM function.
