hi all,
I'm trying to flash my netduino in order to upgrade to 4.2. I'm following http://wiki.netduino...ep-by-step.ashx but running into a problem pretty quickly.
SAM-BA 2.12 "Select the connection" has an empty drop down, as though the n+ isn't around. It's plugged in (I double checked ;-)) and Windows has added it as a device.
Any idea to get me going?
Cheers
Andy

Hi!
Just a question, how does Windows call it? If it still sees a "Netduino" in the device manager, it's not yet reset.It's plugged in (I double checked ;-)) and Windows has added it as a device.

Ah-hah! It is Netduino, good intuition.
I must have not hit the erase properly (tentative worried fingers...) I'll retry.
Many thanks

Don't forget to power off the netduino after resetting it. Powercycling between the different flashing states are proven to be helpful
So:
1. power on the netduino
2. erase all firmware (including the tinybooter)
3. power off and back on the netduino
4. install the tinybooter
5. power off and back on the netduino
6. install the firmware
Then you're settled

Perfect.
I also had to install the x64 driver for Windows from the wiki, and I had to erase twice as I started getting an error (attached) from the Amtel tool. Once I'd gone back to a fresh erase (3v3 to pin under 0) the problem went away.
As a side note, to document my experience I also found that I was using the wrong MFDeploy (one I downloaded from Microsoft rather than the one C:\Program Files (x86)\Microsoft .NET Micro Framework\v4.2\Tools) and that couldn't see the Netduino to upload the firmware.
Once everything was in line, driver, amtel tool, mfdeploy and the netduino bits, the flashing worked first time.
Thanks for the support,
Andy
