Assembly Error Fez Mini


#1

2 months ago I’ve been playing around with the FEZ Mini, DC Servo and a reflective sensor. This worked great.

Since I ordered some new sensors I started to play around again…but i’ts not working.

When I use the FEZ teemplate in visual studio I can run the program and the led starts blinking. When I referen the using GHIElectronics.NETMF.Hardware assembly it stops working and I get the following message in my output window:

Error: a3000000

Waiting for debug commands…

The program ‘[2] Micro Framework application: Managed’ has exited with code 0 (0x0).

I have reinstalled my PC and reinstalled the SDK. Maybe I have to update the firmware? I tried this, but I’m not able to update the firmware, I’m even not able to ping the device using MF deploy.


#2

Yes it is update firmware


#3

You need to upgrade to … .NETMF4.1 … you can use “TeraTerm”, or the auto app. “USBiziUpdater” program… if for some reason you have problems… tell us what version of Windows you have and/or what steps you get stuck in.


#4

I got the same error message “Error: a3000000” when I was an old project (prior to June 30) wanted to change.
My solution to this problem is all the “References” remove and re-add
