I just purchased a SAMD11 xplained pro board.

It's installed, drivers work, edbg data driver installed cleanly. as i can see in device manager.

As soon as i plug in the board it crashes the backend agent..

I cant see any tool to program with I should see edbg debug programmer. its not there.

Googling tells me that atmel studio has a backend agent that will read the board and pull up the programming tool.

I've reinstalled atmel studio 7. (Version: 7.0.2397 - )

nothing. backend agent still crashes when plugged in. if i start atmel studio with the board plugged in, the agent loads crashed.

yes I am plugin into the debug USB not the target usb.
 

Why oh why is this so difficult.

Out of interest - do you have MPLABX installed too?

(I think there is a shared USB-layer... :/ )

I have just hit the same exact issue. If I start Atmel Studio with nothing connected I can see the simulator.
If I plug my JtagIce it shows up.

As soon as I plug my SAM4S Xplained Pro (EDBG) the backend crashes and everything else disappears too.

 

Has anyone gotten to a workaround?

 

This is smelling bug to me.

 

Can we roll back to previous versions of Atmel Studio?

I found out that at the same time you can't have enabled both COM & EDBG ports in Windows. It doesn't work and it stop the backend agent. Disable EDBG driver and you will be fine. I found that I can use EDBG driver with COM together when I need to use onboard Current Measurement System witch start the Data Visualiser automatically.

No, that's not true.

 

I have certainly used COM and EDBG together.

 

You must have something else going on.

Do you mean COM port, or the Data Gateway interface?

I've had problems where disabling the latter "fixes" a unfindable progranming interface.

I *think* that the DGI is separate from the CDC interface, ie you'll normally get three USB things that show up:

 

EDBG Data Gateway

EDBG Virual Com Port

USB Input Device (HID-complian vendor defined device)

 

The Data Gateway (which apparently does SPI, I2C, etc) is the one I've disabled and had better luck...

I've not had problems using all 3 together.

I think you're right

That's not denying that problems do arise!

My point (also in #6)  is that there's no inherent limitation on using these things together

Have you tried disconnecting all other USB devices?

 

See: https://www.avrfreaks.net/commen... - turns out there was a conflict with the keyboard!

 

EDIT

 

Which goes back to this: https://www.avrfreaks.net/commen...

My SAMD21 Xplained Pro does not appear in studio.

 

 

I have no other USB devices attached. I had MPlab X installed but since removed.

 

Which drivers need re-installing ?
