Segger has released several upgrades for both ST boards and Atmel EDGB boards converting them into Segger OB, I know because I've upgraded all my STs and it seems I've upgraded an Atmel SAM4S at some point. I now have one other Atmel board, a SAM D21 Xplained Pro but I can't work out if there is a Segger OB upgrade for it or if this board needs to continue to run in CMSIS-DAP mode. The documentation from Atmel seems to indicate it is compatible, perhaps they ship their new boards with OB installed, mine's old. If there's a link for upgrading the software on it, can you point me to it please.

Thanks

Thank you Niklas, as usual. Possibly worth pointing out I typed "Atmel", "Atmel EDBG" and "Atmel D21" into the search box and didn't find that page, or actually any page. Am I using the search incorrectly? I will upgrade the firmware tomorrow when I have access to a windows box, I so prefer the JLink interface to the EDBG one.

I disabled my web tracker blockers and now I see results. Unfortunate that you now have to have web blockers active as default.

All good now, Segger whitelisted and again, thanks for your help.
