In Topic: Solution deploy failures for VM users

15 May 2011 - 05:58 PM

Have you tried this technique to reset ?

Well, I have netduinos that have been 100% erased, including sometimes the bootloader being replaced, many times. I have one hooked up right now that is "factory fresh" with no messing about at all. And I have tried lots of things in between, including most all the pre-release software images. The first one I got has the little erase pad about worn out!

I am uncertain exactly what that linked procedure is trying to do. I am suspecting the board doesn't need reflashed or erased, it is working fine. The problem is Visual Studio under VirtualBox hangs between the deploy and entering the debugger, apparently due to some kind of failed handshake with the Netduino, but that is a guess. Jacking the board allows it to go into the debugger and things proceed from there.

To date, most of my Netduino time has been running FreeRTOS on the little things. But I wanted to get back to trying the C#/.NET stuff and maybe learn something. So far, using VS in VirtualBox has resulted in a less than reliable development cycle. I am sure there are very few of us, wanting to use VirtualBox under Linux...

EDIT: I should also point out that this is functioning well enough to do development, it is just an additional step is needed to jack the board.

If you press the reset button on your Netduino Plus when "rebooting..." gets stuck, does that fix the VM deployment problem for you?

Not really. I tried 4 times just now, each stuck at the rebooting... message, and then I pressed the reset button.

The reset button caused the new version of the program to start after a few seconds, but Visual Studio was still stuck at rebooting... message.

After the reset button test, I then jacked the USB, and each time it went into the debugger from there.

In Topic: MFDeploy: Deployment Status "Executing Application"

12 May 2011 - 12:38 AM

1) When deploying the new beta firmware, MFDeploy gets to the stage "Executing Application" and then hangs there. Is it finished? I try hitting "Cancel" but the only things that works is unplugging the USB.

2) Any hints on getting the MFDeploy menu "Target->Configuration->Network" to come up? I click that and then MFDeploy just hangs... If I unplug the USB at that point, I get a message "Device has old or unsupported configuration"

This is interesting, I have seen these same issues repeatedly, and assumed it was because I am running on XP in VirtualBox. Guess not related to the VM after all. Do you ever get hangs or crashes from a normal solution deploy from within Visual Studio?

In Topic: Netduino Plus 1 Firmware v4.1.1 BETA 1

09 May 2011 - 10:44 PM

If you reflash your device with the v4.1.0.6 production firmware do you see the same spotiness with USB connectivity?

V4.1.0.6 does work better, as does V4.1.1.0Beta1. VS terminated once on the first deploy with V4.1.0.6 and never saw that with V4.1.1.0Beta1, might have been coincidence. Jacking the USB is sometimes required to get deploy started, but with some fooling around it works.

The problems with VS locking tight seem specific to the 42KB_RAM version. Those crashes require sending the ol' CTL-ALT-DEL and killing VS. Didn't see that with the other versions. Does this make any sense?

For now I will use V4.1.1.0Beta1 for some .NET learning...

Hi Chris. Virtual Machine feedback was requested: I am finding about the same reliability as with prior versions. I actually used the 42K RAM version, if that matters. The setup here is Virtualbox 4.04 with the USB extensions, running on Ubuntu 11.04, with the Windows OS being XP SP3 fully patched up. The USB operations are spotty, it would seem. Sometimes things just lock up, sometimes the Netduino gets programmed and then VS locks up. Sometimes things work. Is the USB operation rock solid on a "real" windows (non-virtualized)? I was hoping for a better go this time, because with this version of VirtualBox, USB has been operating fine with odd devices such as programmers. If you have any particular tests you would like to run let me know! For now I will put FreeRTOS back on this little guy... hope we can get things worked out though, it would be fun to join the rest of the users on .NET C# and learn some of that too now...
