Hello Willi, the UDOO probably isn’t supported as of now.
ARM boards usually have some kind of board identifier. This is used to identify the board, to find out which serial console port it uses, if it has sdmmc slots, and lots more board specific stuff. The kernel itself supports the i.MX6 SoC , but it doesn’t support any i.MX6 based board out of the box. You’ll need to feed the kernel some information about the board, so that it knows how to behave when it „sees“ it. Basically, you’ll need to look at some UDOO-supported u-boot/linux source repository and feed the needed information into sys/arch/armv7/armv7/armv7.c, sys/arch/armv7/imx/imx_machdep.c and some sys/arch/armv7/imx/imx* drivers. \Patrick Am 12.12.2013 um 14:30 schrieb Willi Huber <surfersparadise85-open...@yahoo.com>: > Hello all, > > I am happy having at least the chance to get OpenBSD running on my machine as > I first thought > of buying a Raspberry PI. > I am pretty new to the OpenBSD and embedded world.
