In the earlier versions of Netduino, you could clear the board by touching 3.3V on a gold pad.  Is there such a thing for Netduino 3?

Hi Greg,

With Netduino gen2/gen3, we have a new streamlined procedure for updating the board.

Grab a copy of Netduino Update (included in the latest firmware over on the downloads page). Then press the button on your Netduino while powering it up via your PC's USB port. Then, in Netduino Update, select the device and press "update". This will erase and reflash the board.

If you want to completely erase the board for some other reason (native code hacking, etc.), you can also erase the board completely using ST's STDFU Tester (bundled with ST DFUSE tools).

Does that get you up and running?

Welcome to the Netduino community,

Chris

I have three boards now.  One is not working...  I tried the 2 procedures and they did not work.  I was wondering if there was more I could do.  The board will go into DFU mode.  The erase procedure seems to work.  When I get to downloading, it will download but not verify.

 

My two other board are working...

Hi Greg,

Do you have screenshots of the procedure you're using for flashing the board via DFU? Let's focus on the ST DFU tools for now...those are the "failsafe backup" and should work regardless.
