OK, I figured it out.  I needed to stop certain programs from running at the same time.  I am not sure which ones were the problem, though, becuase I stopped pretty much everything I could, and after that it worked.

Strange.

A couple of things I ran across that needed attention before I could get my converted (Plus-1 to Plus-2) project to work. 

1. It seems that it is much better to start with a new VS project and copy only your source code over.  VS does not seem to do a good job of upgrading an exisitng project from VS2010 tro VS2012.  Once I took this approach I was able to make progress on getting my GPIO pins to work on a Plus-2 board.  Some items needed new definations, as for example, I wanted to continue using the original Secret Labs PWM calls.
2. My shield has a watchdog timer built into it, mostly because the Plus-1 Netduino board frequently locked up the processor when doing TCP/IP operations.  The Plus-2 board adds 'Header Power Switches' that delay providing power to the headers until some time after boot.  The upshot of this was that my watchdog circuit was not powered up and so held reset low and so the Plus-2 processor never booted, continuing to prevent power from reaching the shield.  Deadlock.  Providing local power to the shield's watchdog circuit fixed this.

So I have basic functionality now.  I am continuing to test and curious how this new board's performance compares to the original especially in the areas of reliability and stability.

Hello!

Did you actually post your question? I surmise he's busier then usual in developing the next generation devices, or even writing the firmware for the currently unsupported modules.

 

Dr. Who,

Thank you for your reply.  Yes, I did indeed post my question.  It's post #107 in the thread "Netduino Plus 2 Firmware v4.3.1" no replies after several days.  Perhaps someone will answer it, perhaps I will solve the problem myself without help.  But having Chris unavailable for several weeks in a row is worrysome.

I am trying to move my current hardware/software product from a Plus solution to a Plus2 solution.  I tested my addon board with a Plus Netduino, and it is working well.  But when using the Plus2 board none of the I/O other than the Ethernet seems to be working.  My Plus platform and my Plus2 platform are on different computers, BTW.  The Plus2 is on a Windows7 machine, running VS-2012 Express for Windows Desktop.

I have upgraded my NetduinoPlus2 to 4.3.1.0 as per instructioons/files posted here.   I am concerned in that the assembly:  SecretLabs.NETMF.Hardware.NetduinoPlus is included.  I was expecting something like Plus2.

Is that the correct assembly for the Plus2 board?   If not, is there a seperate download for the Plus2 hardware assembly?  Or am I doing something else wrong?

Thanks for any help offered,

Robert
