Bearer of Bad Tidings … Or is it just me?

I had some code that ran on my G120E Dev. Board when using firmware 4.3.7.10.

To me it appears there is something wrong with pin assignments (But what do I know?)
Using the same code with 4.3.8.0 fails.

Test example of the code I used to show the errors. The pin assignments worked in 4.3.7.10

Maybe it is me but I think it should work without exceptions.

Thanks for your time.

EDIT.. Ignore the following. This was MY error due to a stray bit of code
/* Also causes exception
 * 
    //Exception System.Exception - CLR_E_PIN_UNAVAILABLE (1) Button.Left value = 85
    interrupt_ports[2] = new InterruptPort(Button.Left, true, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeHigh);

@ willgeorge -

In 4.3.7.10, Pin reserved function is ignored, but in 4.3.8.0, it is active.
Meaning you can not use a pin if that is reserved.

@ Dat -
Thanks for the reply.

Forget everything… My error.

I was testing something and I left a bit of code that was used elsewhere.

private const Cpu.Pin WIFI_CS = G120E.Gpio.P3_30; //SPI_CS (Slave Select)
private const Cpu.Pin WIFI_RESET = G120E.Gpio.P4_31; //RESET#
private const Cpu.Pin SPI_INTR = G120E.Gpio.P2_30; //SPI_INTR

I forgot to comment the line below
//private static OutputPort WIFIReset = new OutputPort(, true);

As you can see G120E.Gpio.P4_31 was used twice.

DANG! I hate it when I am so stupid!
