I hope that you might make a mini version of the Go at some point, with lots of pins...

[StanDeMan]

A mini version is my wish, too. Thanks cys. Cheers, StanDeMan

Thanks for that response however I need to access a USB device, not create one. The arduino mega adk has a USB host port that we can use to connect to the device with an ftdi driver, looking for similar in a netduino style.

Actually, since thisGadgeteer Serial to USB Module is a U-type of module, it can be used with Netduino Go!

I have just completed a design using the netduino plus, can i use the netduino go instead of the netduino plus to achieve the same? Can i connect to the pins directly like the netduino plus or do i have to connect using another method?

Oh boy, two boxes of stuff from Amazon waiting for me at the office when I arrived this morning. It is GO time

I am sure this is a really dumb question, but my Netduino Go came today and I am trying to use it. When I deploy my project (simple program to make the RGBLed module glow red) I get an error:

Cannot deploy the base assembly 'mscorlib', or any of his satellite assemblies, to device - USB:NetduinoGo twice. Assembly 'mscorlib' on the device has version 4.2.0.0, while the program is trying to deploy version 4.1.2821.0

Where do I get the correct version?

Hi and welcome to the Netduino forums.

This is a very common issue. The Netduino Go! framework requires .NET MF 4.2, and your project is set to 4.1.

Open your solution in Visual Studio and double click the "Properties"-page underneath your project in the Solution Explorer window. Go to the "Application"-tab. You can both see and change the target framework here. If it won't show up 4.2, you'll need to install the latest SDK from http://netmf.codeple...ases/view/82448

If your solution contains more then one project, you need to do this for every project in your solution!

[FooWho]

Thank you very much! I followed the instructions to upgrade to 4.2 and now it works great.

Quick updates: Full source code to the Netduino Go and Shield Base firmware is now posted on the Downloads page. This code was contributed by community member KodeDaemon, who spent many months of free time and weekends on it. [Thanks Kode!] We've signed the official .NET MF 4.2 drivers and are now in the process of building and testing the installer. All of the files you need to get up and running with Netduino Go are in the "Early software and instructions thread" pinned in this forum...but we will also have a nice SDK with templates for Netduino Go and official signed .NET MF 4.2 drivers shortly. The design files for the modules are on the main website and Wiki. If there's any source I've missed, please let me know and I'll get it posted! Thank you everyone for your patience these last few days while we have been getting everything uploaded. And please let us know how you are liking your new hardware! Thank you, Chris

Hello, which compiler you use for build NetduinoGo firmware ?

[Nevyn]

which compiler you use for build NetduinoGo firmware ?

Looks like I've just managed to compile the 4.2 firmware for the main board with CodeSourcery Lite (GCC 4.6).

Now just need a board and then time to sit down and work out what to do with it

Mark

Hi x893,

Hello,
which compiler you use for build NetduinoGo firmware ?

We used RVCT (ARM RVDS 4.1) to compile the Netduino Go firmware.

CW2 did quite a bit of work to get it to compile under GCC (using Yagarto...maybe CodeSourcery) as well. This is not tested, but we do want to make sure that everything compiles under the free GCC compiler as well.

THANK YOU! I tried compiling 4.1 from the NETMF sources but it was a jumbled mess and I couldn't figure it out. After a couple hours I was like: "I has a sad" and gave up. But I still strongly desire to tinker in the native layer to add in some things I think would be useful for me and test them out. I don't like the idea of asking others to make the change to see what happens and I won't blindly send a pull request or merge source that I can't test myself!

Chris - You're my hero for inspiring such awesome people.
CW2 - I will grant you one wish. Within my power to grant. And if it's not too troublesome or very illegal. Unless I'm incapable of making it work again.

I've not been successful getting the firmware to compile using CodeSourcery Lite gcc4.6
I have had to do a number of things to get further with it:

1) The Microsoft.Spot.system.gcc.targets file is missing conditions for COMPILER_TOOL_VERSION 4.6.
2) It is also missing the cortex-m3 processor type.
3) It is also missing including a -mthumb parameter in a few places.
4) Some UINT32(unsigned int) vs. uint32_t (long unsigned int) type issues in the core USB drivers.

Maybe I've missed something fundamental.

a quick overview of the basic steps I have performed:
install the PK4.2QFE1
Copy files from the Netduino Go firmware zip over the top of the PK folder
install CodeSourcery Lite (GCC4.6.1) to c:\gcc
install VC++ Express (to get the command prompt environment, msbuild, etc.)
open a VS Command prompt
cd to c:\MicroFrameworkPK_v4_2
setenv_gcc4.6cmd c:\gcc
cd solutions\NetduinoGo
msbuild /t:build /p:flavor=release;memory=flash


Did you run into the above issues? If so, I'd appreciate if you can advise me on what you did to fix them?

The firmware source patch for GCC-based toolchains will be released soon. Please stay tuned.

That's great. Your efforts are very appreciated.

If I may ask my first of many dumb questions, where can I get more go!bus cables?
