Trying to deploy the template Meadow project app and got error. Log:

When trying to update Meadow.OS got error:

any suggestions?

I get the same error when deploying various sample projects.
I was able to deploy the HelloMeadow sample project successfully without error.
I then tried to deploy the Simon project and received the error below.
Now when I go back and try to deploy the HelloMeadow sample project, I continue to get the MeadowDeviceManagerException error, though the app is deployed and runs successfully.
Tried re-flashing the Meado.OS… didn’t help.

I am also getting the same issue with no way to fix it, I tried re-flashing the micro and tried following the install directions again and had the same issues

Hey folks,

I’m sorry to hear you’re having trouble. Can you make sure that your Visual Studio extensions is updated to the latest and also use the Meadow CLI to flash the latest OS to your Meadow?

Let me know if this helps.

I had similar issues upgrading from 3.10 to 4.4. I updated my VS extension and my CLI at which point I could no longer update my meadow or deploy to it. I used dfu-util to copy over the 4.4 os file and after that I was able to perform the regular download and flash sequence using the latest CLI.

This was the dfu-util command I used (from my firmware directory):

dfu-util -a 0 -S 306735813238 -D Meadow.OS.bin -s 0x08000000 &&
dfu-util -a 0 -S 306735813238 -D Meadow.OS.Runtime.bin -s 0x08040000

canderson, did you upgrade from 3.10 directly to 4.4? Looking at your solution I assume there was a compatibility issues between the FW on the board and the VS extension?

#7

I am seeing the same problem when deploying the sample application.

I just ran through the Getting Started Guide so I assume I have the latest of everything.

I’m developing under a VM (Latest VMWare with Windows 10).

Note I get the same exception thrown when run meadow --MonoEnable during the setup guide.

Any suggestions?

EDIT: I use USB-C adapter to connect it to my Mac.
EDIT2: I tried on my Windows laptop and getting the same error.

I also have this error now.

A week ago I was able to successfully complete the update and also provide a program again.
Now I wanted to continue actually and also encountered the exception error as described here in the beginning.

What have I changed? The connection with the industrial interface I²C. Also from the template whose test application can not be provided.

The exception ‘MeadowCLI.DeviceManagement.MeadowDeviceManagerException’ always comes when the Meadow is restarted. That’s all I’ve noticed so far.

Hi.

I am getting the same exception:

It was working, but something went wrong, and now I am stock and I cannot get it to work again.

I believe everything is fully update.

Best regards,
Kristian.

Just adding my voice to the chorus. Seeing the same thing here too - after installing what I believe to be the latest beta4 build/tooling

Update - got some action from this thread here but still nibbling around the edges.

I’m genuinely curious why there’s a special step to update Mono - and why that’s also not documented in a way that says “oh hey - when you update to use the latest beta you need to these steps…” that includes running “meadow --UpdateMonoRt”

Did I miss a memo?

#12

The latest CLI has rolled all the updates into 1 command, meadow flash os so you shouldn’t have to worry about mismatched versions anymore.
