Essentially this is exactly the same device as Trats2 so everything should work... but debugging would be hard if you don't have the Anyway JIG. If anything goes wrong then maybe you could restore original image... or not. :) The Trats devices were given to developers during Tizen Developer Conferences and some time after. I remember that some division in Samsung America was providing these to individual application developers few years ago. I don't think they do now. Anyway Samsung was releasing (and was giving away) new devices on each Tizen Developer Conference. Last year it was Gear 2: https://www.tizen.org/ko/events/tizen-developer-conference/2014/great-tizen-developer-conference-2014-giveaway-gear2-nuc This year the conference is in China: https://www.tizen.org/ko/events/tizen-developer-conference/2015 > >> Standard Debian works fine on them.

The Debian was chosen for a testing platform.

There was a reluctance on LKML to accept camera drivers without releasing the firmware. Samsung never released the firmware on any website however you can download it from the device and find it on unofficial website: www.sammobile.com/firmwares (this website is not related to Samsung) Some drivers were not even upstreamed (like touchscreen driver for Gear2) but you can find the sources on vendor's site or on tizen.org. Again you will have to get the firmware from unofficial site or from device image directly (maybe here: https://download.tizen.org/snapshots/tizen/mobile/latest/images ?) Best regards, Krzysztof
