Problems after installing GHI Software Package v4.2 Update and performing a firmware update

I installed the GHI Software Package v4.2 May. 1, 2013 and did a firmware update on a Hydra board using the FEZ Config (Beta) software. I can connect to the board without any problems:

Connecting to device…FEZ Hydra_Gadgeteer
Loader (TinyBooter) Version:
Firmware (TinyCLR) Version:

Now the project that was working will not deploy to the device.

I’m getting an error during deployment that says:

“Link failure: some assembly references cannot be resolved!!”

Then I’m getting a message that it needs versions

… needs assembly ‘GTM.GHIElectronics.Display_T35’ (
… needs assembly ‘GTM.GHIElectronics.UsbClientDP’ (
… needs assembly ‘GHIElectronics.Gadgeteer.FEZHydra’ (

If I check in the project References, these are present but they are version

Any ideas on how to resolve this?

@ dwc - Looks like you need to remove and re add the references for the t35, client DP and fez hydra. This happens when you upgrade and load an older version project. The easiest way would be to start a new gadgeteer project and copy your code into the new project.

And welcome to the community too :slight_smile:
