After waiting months to have proper equipment recommended from the various posts I am still unable to flash the Netduino Mini (MINI) following the wiki in order to update bootloader for 4.2 http://wiki.netduino...duino-Mini.ashx

https://www.sparkfun.com/products/8552 & https://www.sparkfun.com/products/429 to connect Key Span to breadboard.

Things I have tried:
After using the only COM port (only one connected is the keyspan) under SAM-BA:using connection = COM1, board = at91sam7x512-ek it just hangs. I thought it had exited and tried to run again except the port was not listed. In case something went wrong with config I restarted my system. Tried again and waited 30 minutes. Instead of killing the process I unplugged the USB portion of the keyspan and received the error in the image attached. I have tried all above version of SAM-BA.
I have also tried running SAM-BA with admin(elevated) rights.
I was able to get Echoes using Putty (http://www.putty.org/) when the RX&TX pins were shorted via breadboard.
I thought perhaps I had reversed the RX and TX so I switched them (maybe the breakout board was wrong?) and got a communication error from SAM-BA.
I have scoured the forums and have tried every solution that has worked for the original poster having similar issues (I made sure to have all the equipment that has been suggested before this attempt.)
Perhaps a driver? I ordered this MINI 6 months ago and this is the first Time I have had the tools and equipment to hook it up per the suggestions from the WIKI, posts from Chris and others. The LED of the keyspan does blink while SAM-BA is hanging although Task Manager does not show an increase in any resource or action(memory, i/o, etc...).
I have checked the connection from topside of chip to breakout board with Fluke 179 (http://en-us.fluke.c...bid=qc0nQZPj2Bk) and have not found any loose connections or shorts.
P.S. I just hit F5 when I wanted to post this.
