FEZ.Feather WiFi not working

SITCore SBC
1

Hi all,
I’m new to TinyClr and have first my experiences with FEZ.Bit using WiFi connection. That all works very well out of the box.

Now I’ve tried to port the code to a FEZ.Feather board. Using the same code I only changed the GPIO- and SPI definitions from FEZBit to FEZFeather. (I’ve also tried both SPI on Feather)

Definitions are for FEZ.Bit:

//Setup Pins
            var enablePinNumber = FEZBit.GpioPin.WiFiEnable;
            var chipSelectPinNumber = FEZBit.GpioPin.WiFiChipselect;
            var irqPinNumber = FEZBit.GpioPin.WiFiInterrupt;
            var resetPinNumber = FEZBit.GpioPin.WiFiReset;
            var spiControllerName = FEZBit.SpiBus.WiFi;

and for FEZ.Feather:

//Setup Pins
            var enablePinNumber = FEZFeather.GpioPin.WiFiEnable;
            var chipSelectPinNumber = FEZFeather.GpioPin.WiFiChipselect;
            var irqPinNumber = FEZFeather.GpioPin.WiFiInterrupt;
            var resetPinNumber = FEZFeather.GpioPin.WiFiReset;
            var spiControllerName = FEZFeather.SpiBus.Spi4;

On the FEZ.Feather calling networkController.Enable() throws a System.InvalidOperationException.
(An unhandled exception of type ‘System.InvalidOperationException’ occurred in GHIElectronics.TinyCLR.Devices.Network.dll)

As said, on FEZ.Bit all is working as expected.
Both boards are 2.2.0.6500; Visual Studio 2022 on W10 Enterprise.

Please can give anyone an advice what I’m doing wrong?
Thanks in advance
Greetings Juerg

I think FEZ Feather uses SPI3 for wifi, not SPI4.

var spiControllerName = FEZFeather.SpiBus.Spi4;

to

var spiControllerName = STM32H7.SpiBus.Spi3;

Thanks, works!

We just added

FEZFeather.SpiBus.WiFi

If you want to tweak your code.
