Question Anyone got the Code for the UAMP-2 and RVL-PMS-2?

[ScrambledFrequency]

I've been thinking about building a Clone of the UAMP2 and PMS2 as a small side project so I can manipulate the form factor and make them easier to modify.
My only question is, where is the code to flash to the chips?
I can't seem to find it, and I'm pretty sure it's open source.

The code for the PMS1 and U-Amp1 are open source (I hyperlinked the githubs), but the the PMS2 and U-Amp2 are not open source.

OK.
