Add the full ICE qSPI signals to the PICO #3

Closed vr2045 closed 2 years ago

vr2045 commented 2 years ago

So the request is to add the full qSPI to the ICE flash to the RPi as well so it can be used to program/read the ICE flash faster. I think this makes sense. Given that we wont be running this interface very fast anyway, this should work out.

We're out of pins on the PICO. Adding the 2 qSPI signals to the RP would be nice to have but would mean that we lose some functionality. Currently have a dedicated 8 bit bus as well as a single dual PMOD from the PICO, RGB LED, FPGA programming control and a couple of ADC channels. I dont see how we can support this so closing the issue.
