Hello, I have a windows 8 pc that I'm trying to setup to play with my N+, everything worked fine with the last project (on Win7) and now decided to do another project and not getting anywhere. First I couldn't load any projects on it, so decided I'd reflash it. I did the 3V3 + copper pin, and it came back as GPS camera.. So far so good. Loaded SAM-BA, started it up, selected the chip and the com port but I get an error while trying to connect. The error is something like: Error h_handle returned zero while executing "TCL_Open $target(connection)(" invoked from within "if{$::argc >= 2}{... Is SAM-BA not going to work with Win 8?

Weird, went to win7 machine and it connected to it there, but tried the second time and got the same error, tried a few different times on the win8 machine and it connected...

It is one of those situations where drivers for USB are not totally compatible with previous windows versions.

Hi viktor, There seems to be a compatibility issue between SAM-BA 2.12 and Windows 8. Atmel should be aware of the issue, but it probably wouldn't hurt if you pinged them and made sure they heard more voices :) I have had success using SAM-BA exactly once after reboot. Any further launches gives me that error. If I reboot my PC, it works again. I know that's not an optimal workaround...but perhaps rebooting (and then unplugging and re-attaching your Netduino before starting SAM-BA) will help for the moment. Chris
