I have a SAMD21 XPro with a WINC1500 XPro on EXT1, an I/O1 XPro on EXT2, and an OLED1 XPro on EXT3. The first time I attached to the DEBUG USB Atmel Studio saw the SAMD21 and the three extensions.
I built an example project and hit the debug button, and was prompted to upgrade the mEDBG firmware from 2.10 to 3.0, which I did. After that the project downloaded and ran, but Atmel Studio no longer sees the extension boards when I attach the USB cable? Apart from Atmel Studio not seeing the extensions, everything appears to be working.
Has anyone else seen similar issues when upgrading mEDBG firmware? Should I worry about it?
