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
