After going over the pinouts of the RP2350, I realized that my “assumption” in fact made an ass of me.
Following the examples from Adafruit, they have you using A3 as the SPI CS.
BUT… Not ALL XIAO boards have an A3. They all DO have a D3 pin.
SO, while I followed the Adafruit example code, turns out RP2040 and ESPC3 boards have an A3 pin but NOT the RP2350.
So, changing the defines to use D instead of A (D3 instead of A3) in the code…
RP2350 no longer gets a timeout.
