Unknown processor for B3?
There is no processor defined for B3, it will throw when creating I2CDriver.
I have a similar issue, it looks like recent kernels have changed the way the processor is reported. See content of /proc/cpuinfo below. Hardware is BCM2835 instead of BCM2709 in previous versions, so I guess some values should be added to the Processor enum list
pi@raspi:~ $ more /proc/cpuinfo

Yeah, for the time being I simply use the same stuff as RPI 2. It works for me though I had to manually build all raspberry nugets I use.
Hi !
I think this could be fixed by changing the "ProcessorName" Function:
public string ProcessorName
{
get
{
// https://wiki.openwrt.org/toh/raspberry_pi_foundation/raspberry_pi
switch (Model)
{
case Model.A: return "BCM2708";
case Model.APlus: return "BCM2708";
case Model.BRev1: return "BCM2708";
case Model.BRev2: return "BCM2708";
case Model.BPlus: return "BCM2708";
case Model.ComputeModule: return "BCM2708";
case Model.B2: return "BCM2709";
case Model.Zero: return "BCM2708";
case Model.B3: return "BCM2709"; // BCM2710
default: return "UNKNOWN";
}
}
}
Maybe there should be another addon to add the hardware type BCM2710 for the Pi 3. But it works with 2709, too.

Fixed adding "Bcm2835" in Processor.cs
For CM3 (Compute Model 3) also needed to modify Board.cs: `private Model LoadModel() { var firmware = Firmware; switch (firmware & 0xFFFF) { case 0x2: case 0x3: return Model.BRev1;
case 0x4:
case 0x5:
case 0x6:
case 0xd:
case 0xe:
case 0xf:
return Model.BRev2;
case 0x7:
case 0x8:
case 0x9:
return Model.A;
case 0x10:
return Model.BPlus;
case 0x11:
return Model.ComputeModule;
case 0x12:
return Model.APlus;
case 0x1040:
case 0x1041:
return Model.B2;
case 0x0092:
case 0x0093:
return Model.Zero;
case 0x2082:
return Model.B3;
case 0x20A0:
return Model.ComputeModule3;`
And ` private ConnectorPinout LoadConnectorPinout() { switch (Model) { case Model.BRev1: return ConnectorPinout.Rev1;
case Model.BRev2:
case Model.A:
return ConnectorPinout.Rev2;
case Model.BPlus:
case Model.ComputeModule:
case Model.APlus:
case Model.B2:
case Model.Zero:
case Model.B3:
case Model.ComputeModule3:
return ConnectorPinout.Plus;
default:
return ConnectorPinout.Unknown;
}
}`
Will the nuget packages be updated with a fix for this issue?
Can anyone suggest an alternative package that works on recent vintage Pi's?
Hey DWalton4, check out this repo: https://github.com/JTrotta/RaspberrySharp
Maintained nicely and this guy will likely have/create an update!
