Well that sounds a bit easier. I assume by "found" that mean's created via the pin file? As in if the frame pin is just left out of the pin file it uses discrete CS lines rather than CS address lines?. If a frame pin is found for a BSPI channel, the external
decoder firmware is built, if not, the decoder is built into the firmware.

Yes, no frame pin means the CS pins are decoded
chip selects rather than chip select addresses.
7I92 and 7I92T configs using BSPI with internally decoded CS pins:

I just got the new rev PCB assembled and flashed the 7i92t, then I realized that firmware was probably meant for the original rev. Probably got mixed up, I posted this pinout on the 26th...
Some pins moved and it's using the MOSI pin with no decoder IC. The inputs are muxed now.

I'll try and get to this before the end of the week

PCW, I assume you're still watching this thread.....
I just picked this thing back up again after quite some time and am repurposing it for sort of a "dual role" machine. I need to add another PWM output, I assume I can't just modify the pin file for the 7i92t since the other file is a binary right?

No the firmware has to be rebuilt and the FPGA reprogrammed. It's not so hard to build firmware yourself.

If you tell me the new PWM pin number or GPIO number is needed, I can add it
(Probably tomorrow)

I suppose you mean with the Efinix software? If ya get bored and wanna point me in the right direction......No the firmware has to be rebuilt and the FPGA reprogrammed. It's not so hard to build firmware yourself.
