Are there any spare GPIOs available on the VGA demo base if the sound and SD card are also in use?
There’s a group of six pads labelled “GP21”, “GP20”, “SDD2”, “SDD1” and “SD JUMPERS”, but no documentation that I can find that says what they’re for. The actual GP20 and GP21 pins appear to be connected to the SD card for QSPI mode.
I’d really like to run an SPI interface into this board to use it is a co-processor for another project.
