Just tested this one on a normal Netduino:
http://forums.netdui...dpost__p__10726
Still bugged in 4.2.

Also, I noticed that when deploying exactly the same project a Netduino Plus, it gives an error on:

StorageDevice.MountSD("SD", SPI.SPI_module.SPI1, Pins.GPIO_PIN_D8);

An unhandled exception of type 'System.NotSupportedException' occurred in SecretLabs.NETMF.IO.dll

So with a Plus, it's not possible to mount an additional SD-card I suppose?

Correct At least for now. This might be something that could be enabled in the future though!

Would be nice to support multiple storage devices, although it doesn't really have hi prio I suppose. The bug itself I mentioned can be annoying though. Any plans for that?

Oh dear, that SDK should be possible to be installed with only Visual Basic 2010 Professional installed right? Retorical question actually With only VB2010Pro installed, I get "Microsoft .NET Micro Framework SDK 4.2 (beta) requires Visual C# 2010 to be installed."
I consider that a bug since the SDK is also for Visual Basic. Installing C# helped.

Just tested this with the 2011-06-14 NETMF build and seems it's fixed now.

Not quite sure if this is a bug, but when I follow this installation sequence on a clean PC:
1. Visual Basic 2010 Express (VS2010Express1.iso)
2. .NET Micro Framework SDK 4.2 Beta (MicroFrameworkSDK.MSI)
3. Netduino SDK 4.2 (netduinosdk_64bit.exe)
4. Visual C# 2010 Express (VS2010Express1.iso)

and I open a C# .NETMF project, I get the error "The project file '...csproj' cannot be opened. The project type is not supported by this installation."

When I reinstall both SDK's it opens the project without any problem.

Thanks for testing that! Yes, the June 14th build should add support for the Express editions of Visual Studio.

Hi Chris, The blue screen bug I mailed earlier, I opened a Codeplex ticket, but they refer me (and Omar) to you: http://netmf.codeple...m/workitem/1049

[Chris Walker]

How funny. There was a USB bug in .NET MF 4.1 which we patched in the Netduino firmware--but .NET MF 4.2 implemented a permanent fix. I wonder if the fix is causing the issue? Unfortunately, the BSOD is being caused at the Windows driver level. We're using the standard .NET MF driver and Windows. Let's see if we can track down more details so that the NETMF team can figure out a workaround for all boards that can be integrated in the NETMF core. Chris

I agree, but I'm not an expert of things and like we say in Dutch: "van 't kastje naar de muur". Litteraly: "from the cupboard to the wall" but loosly translated being bounced around.
So perhaps you could reply on that issue, or take some other actions? If you need me to test anything, you know how to contact me

Found yet another bug, in VB.NETMF, while typing this line and pressing Enter the IDE crashes the hard way:

Public WithEvents button As InterruptPort = New InterruptPort(Pins.ONBOARD_SW1, False, Port.ResistorMode.PullDown, Port.InterruptMode.InterruptEdgeBoth)

Now there are more ways to handle events but a crashing IDE, not good!

That's fixed now, but when deploying attached app, it gives:

Download the latest version of the MF 4.2 (Beta).

This issue should now be resolved.

Yea I know That's why I tested it again and encountered another issue

[skytribe]

I believe there is another update to the firmware that is possibly required. You may want to check with Chris and try reflashing the latest firmware as well.

The joys of Beta software. Obviously finding issues is part of the process - so its great that people are starting to use it and we can find these.

Some of these will be VB Only issues as Withevents is a VB Only construct. So at least it is not completely blocking event scenarios as its always possible to use the addhandler construct in the same way C# sets up event handlers. Not Ideal but we are working to resolve issues.

[Chris Walker]

Hi Stefan, We'll build updated firmware this weekend to support the latest NETMF SDK. I love that the community is testing this so quickly. Three SDK updates in one week! Awesome. Chris P.S. Thanks for the help and insights, skytribe.

[Joe88]

Hi,

I no longer get the issue that I mentioned earlier in this thread but after doing a reflash and re-install I now get this error when I try to deploy the FTP Sample:

Thanks,

[Chris Walker]

Hi Joe, Can you please do the following? 1. Using MFDeploy, execute the "Device Capabilities" and "Flash layout" commands -- and then copy and paste the results in a post in this thread? 2. Post a ZIPPED version of a simple project which demonstrates this issue? Thank you, Chris

Hi Joe88,

Deploying assemblies for a total size of 76136 bytes

The Netduino Plus has 64KB of flash for code (65536 bytes). Your project is about 10KB too big. It's possible that the FTP classes are too large--or you may have some other dependencies being included which are putting you over the top.

I believe that the FTP classes are managed classes running on top of the HTTP classes. You should be able to import just the FTP source files you need into a Visual Studio project...or even switch them over to using raw sockets.

Chris

[Joe88]

Aha! I should have realized that... I'm currently chopping as much out of the FTP library as possible (all the client stuff mostly.) If it comes to modifying it so that it uses sockets then I'll probably just write my own. I'll post it here though, baptism by fire when it comes to writing embedded code I guess! Joe

I'm having issues mounting an SD card with the new firmware on a netduino plus.

In a previous post it was stated:
"So with a Plus, it's not possible to mount an additional SD-card I suppose?"

Does this mean additional, or any SD card?

I'm trying to execute:

SecretLabs.NETMF.IO.StorageDevice.MountSD("SD", SPI_Devices.SPI1, Pins.GPIO_PIN_D8);

and it just throws a first chance exception.
