ColoradoNetduino

Hello,

I fought through the exact same problems many users are having where the Netduino PLus 2 is locked up with both lights on, and wont be recognized by the USB bus unless it is in bootloader mode -

I took the advise of the earlier post by Chris, and re-downloaded the Firmware, and he was right, I had unknowingly copied (created) a bad firmware into the Firmware file I was trying to use.

After deleting the directory, redownloading the firmware, unzipping it, using STDFU Tester to erase, and then using DefuSe to Upgrade - it worked perfect. 

I had previously been at it all night, when it did work I noticed right away, because the 'Transferred Data Size' was around 384K and before it was flashing 1024k?

Now it works perfectly again.  I will repost the remedy below....

Thanks, JT

The text on them feels backwards, so it's pretty easy to accidentally overwrite your firmware .DFU file with the empty contents of your board...instead of flashing the .DFU file to your board [/color]

Then go through the re-flashing process again, paying close attention to the buttons pressed in each step. Be sure to check the box to verify that the firmware was written correctly.[/color]
