I installed Atmel Studio 7.0.2397 on two PCs. On one PC, everything works as expected: I connect a SAMD20 Explained Pro board, Atmel Studio immediately recognizes it, opens a new tab, and allows me to start a new project with the board. Thus, I know the board is good. On the other PC, Atmel Studio 7 does nothing when I attached the board, and I can't program the board because there is no programming tool recognized:

 

 

During the installation, I installed all options. I made sure all packs are installed. In Device Manager, the EDBG Data Gateway shows up under Microchip Tools when the board is attached. I uninstalled and reinstalled Atmel Studio twice.

 

I don't know what is different between the PC that can program the board and the PC that can't. Does anyone have any suggestions on how to get Atmel Studio to recognize the board so that I can program it?

Hi,

I hope it is not against the forum rules to post in a stale thread.

 

I have quite similar problem. 2 PCs, on one of them the EDBG is working fine in Atmel Studio 7.0.2397, on the other only a "Simulator" is shown. Nevertheless the EDBG interface is somewhat working, the EDBG tool from https://github.com/ataradov/edbg can read the chip.

The chip is SAMG55J19 and the board is "TDK SmartSonic Chirp Sensor Host Board".

 

Have you managed to fix the issue with EDBG not showing in Atmel Studio?

Hi,

I found a solution to my problem. It was a little weird, but it worked for me.

a) Using Zadig I found the EDBG CMSIS-DAP device. I changed the driver to some else. This made the CMSIS-DAP interface unaccessible to third party tools.

b) I uninstalled all the Atmel software in my computer and reinstalled the Atmel Studio.

 

I expect that changing the USB driver to the wrong one was detected and automatically repaired by the installer. It's strange but it works.
