SPI on ZED-F9R

Hi Brent (@brenton.dickinson ),

Thanks for the update. Glad you got it working.

It looks like we introduced some badness when we migrated from the old MISO / MOSI labelling to the new PICO / POCI labelling on the ZED-F9R boards.

In summary:

ZED pin 42 was previously correctly labelled TX / MISO
ZED pin 43 was previously correctly labelled RX / MOSI

The new labelling should be:

ZED pin 42 : TX / POCI (a.k.a. SPI_SDO / TXO (TX Out) / TX1 (TX UART1))
ZED pin 43 : RX / PICO (a.k.a. SPI_SDI / RXI (RX In) / RX1 (RX UART1))

But I see that the updated ZED-F9R silk and schematic use: TXO / PICO, and RXI / POCI. The TXO and RXI are correct. But the PICO and POCI are reversed…

Sorry about that.

I’ll pass the message on.

Best wishes,
Paul
