I realized from previous questions that the firmware source code of the Navio2 board wasn’t released. In fact, there is an ongoing work to release the source code, but there is no eta.
My question is bit different. Since we have no access to what the Navio2 board is doing, can anyone disclose, in a general way, what the processor is doing?
For what I figured, maybe it is just providing Pi access to the sensors, servos, etc. I just want to know if the processor is doing some kind of data processing or implementing algorithms.
I want to use Navio2 with an FPGA (replacing block by block what the Pi is doing). For that I needed to know in fact what is happening in Navio2.
Thanks for the attention.
