I erased the firmware on my netduino and need help restoring it. I was following the steps indicated by the post: http://forums.netdui...p__347#entry347 and I can not get pass step 4 of getting the driver for virtual serial port installed.

When I put the netduino in the USB port, windows does not try to install the ATMEL driver. Windows just left it as unrecognized USB device. Also, when I tried to select the driver specifically, the system complained that the driver is not compatible with windows x64 based systems. However, when I tried to do the step on Windows 32-bit, it also gave the same error of not being compatible with the system.

What do I do? Any other methods to restore the firmware?
Any help is much appreciated.

Hello,
I made this video a while back:
... thats when I was still having mic issues, so mute it and just speed forward to where you are at. Windows never installed drivers for me, I just used sam-ba right way. Also make sure you are selecting the correct files when doing this(Netduino firmware and bootloader for a netduino, or the Netduino plus version of the files for the netduino plus) Hope that helps.

I know how to flash the firmware, but my computer does not recognize the device and I can not use the ATMEL driver. Also, when I try to communicate through SAM-BA, it gives a communication error.

Any Ideas of why this is happening?
Help is really appreciated

I've never had that error... could you explain a step by step process and where the error is withing those steps?

Hi OaftheBear,

A few thoughts:
1. If you have an RS232 shield (or a USB-TTL cable), you can also flash the firmware via serial using pins D0/D1. Please note that you'll need to power your Netduino via a USB charger or a power adapter in this case...as the bootloader will "lock onto USB" if you have the Netduino plugged into a computer.
2. Are you running SAM-BA v2.09 or v2.10? We've had troubles with v2.10 on Windows 7, especially on 64-bit Windows.
3. Do you have access to a Windows XP or Windows Vista machine? Or are perhaps running Windows 7 Ultimate (and so can use Windows XP Mode)? That would make things simple...

Let's see if we can get you back up and running.

And welcome to the Netduino community!

Chris
