Gabi, apologies for the late reply. We posted a lot of documentation about the DragonBoard yesterday and will be posting more over the next few days. Qualcomm are showing it at the ShenZhen Maker Faire today and tomorrow and Arrow have begun taking orders for it. Support will be provided on this forum by Linaro with help from Qualcomm and Arrow and you can find links to the software here: https://www.96boards.org/products/ce/dragonboard410c/#1422454593-1-91
We have also provided a little more information about the types of builds that we expect to become available for 96Boards products and how they will be supoported here: https://www.96boards.org/about/program/#Builds
Please let us know if you have any additional questions.
