I have a problem with the board netduino plus,when i connect the usb to pc all lights stay turn on, and don't work .

I try to reset my app with MFDeploy but when i select usb no device is detected, is the first time.

History before this:

I deployed my app with visual studio ,i have unplugged the usb cable maybe before the end of deployment, the bord didn't work well, i tried to reconnect the usb ma no device was found.

Maybe in the reconnection , a secondary power supply (by battery) was conneted to 5V pin and GDR pin.

How to restore my board?

Hi voiager 6, Try removing power from your Netduino, holding down the pushbutton, and then plugging it into your PC via USB. If it shows up in MFDeploy, press ERASE to erase your current app. If that doesn't work, then please try re-flashing the firmware from scratch (TinyBooterDecompressor and TinyCLR) using the latest firmware for your board. The latest firmware is posted at the top of the respective board forum. If all that fails, please let us know; we're here to help. Welcome to the Netduino community, Chris

Hi Walker,

MFDeploy didn't work, I have tried to install new firmware with TinyBooterDecomp. but when i use samba V2.12 the board isn't found by pc, always unknown device into Controller USB, also with the gps camera driver.

I tried with other PC but same result.

The board is dead?

Hi voyager 6, If you device appears as a "GPS Camera Driver" in Device Manager, that means that it has been completely erased. When you start SAM-BA v2.12, you should select the COM port of the "GPS Camera Driver". I would try unplugging and re-attaching the device immediately before starting SAM-BA, to make sure that the communication session starts from a clean state. If you can't connect to the COM port of the "GPS Camera Driver", you may need to upgrade the driver for that device to the Atmel drivers which come with SAM-BA. I typically stick with the default drivers, but it's an option. Once you get TinyBooterDecompressor.bin successfully flashed to your gen1 Netduino, you'll be able to see it in MFDeploy and flash the corresponding NETMF firmware. Chris

Hi Walker, thank you for the helping.

I understand when i have the COM, i can completely erase.

The problem is that when i try to connect the board to PC, the board result not connected, only at the fourth, fifth attempt, the board is shown on device manager like unknow device, i tried to install the GPS camera driver and the SAM-BA v2.12 driver, but always unknow device.

I remenber the cause was a 5 Volt power line connected,not on Vin pin but on 5V Pin, what damage could I have done?
