Revive Netduino plus 2

Ok.
You mess up your Netduino pkus 2 going to 4.3.1.

How can you fix it? How can you fix it if you have to bring it back to bear metal again, even the bootstrap ot boot loader?

How do you tell how much has to be reflashed?

Is there a list of step by step instructions or tools? The exiting ones did not work for me including pressing the button while poweron.

Thanks!!!

Pete

Hi Pete,

If you hold the pushbutton while powering up your board via USB, what shows up in Device Manager? It should appear as "STM32 Device in DFU Mode" or similar.

Nothing shows up. I am not sure the OS even has the drivers installed right. I think because I went straight to 4.2 instead of 4.3 to be safe.

Then I made the button app and tried to upgrade everything to 4.3. Now the Deploy on VS13 is dead as it seams and can not find the device. at times I get text like iteration 0--> 1,2 3 4 5 etc

but it does not find the device.

 

If I do not have the button pressed it runs my button program blinking the LED when I press the button.

Should I use the wire and pull that pin pad to 3.3 volts?

Is it possible to share a link with the latest 4.3.1 software? are you guys still in beta?

I don't think I have the right drivers installed. The device does not show up in device manager.

It does not show up in the Update-app, in VisualStudio13, or the Deploy Util Either.

Yes it comes up in the Device manager like you said, Now what should I do?

Hi Peter,
 
Grab a copy of the 4.3.1 firmware which comes with NetduinoUpdate:
http://forums.netdui...-firmware-v431/

Then run Netduino Update. You should see your device. Configure it as a Netduino Plus 2, if it doesn't already show up as that, and then flash it with the latest firmware. It will automatically erase-and-reflash your device to factory condition.

Does that help get you up and running?

Chris

Got it update!!!

I'm at 4.3.1 now!!!

Cool

 

 

It seems my win7 box has everything messed up with the drives or something. My win8 box at home did everything great!!

 

1. Now I need a shield to connect Bluetooth for my Netduino Plus 2 and some sample code.
2. I also need an example of talking Ethernet with it and accessing a webpage and getting data from an ASPX .ASHX handler or a WebApi Contoller action with MVC4. Any help on this?

I want to turn on the led with blue tooth. that's pretty basic.

I also want to press the button and get an event on my webpage
