@gollux Can you attach a sample project that has this issue?

There is no real documentation, but here is a screenshot of the data from my logic analyzer. 

the data is not high for 180us it is toggling at 800khz.

The DPI pixel output used by the pi based boards need FPP 6 or newer

That was my intention of this PCB, but the firmware needs to be. I have also looked at an ESP32 based PCB as they are more available. written.https://github.com/computergeek1507/PB_16/tree/master/Teensy_16_SMD

is this the SMD or regular version?

My only request is that it's licenced under an open source hardware license, so myself or others can use it and modify it.

BBB 16-SMT or BBB 16-SMD is fine with me

I was wondering as well, if not I will start one

You need to set the J23 jumper to 5V
