Hi Oliver, I do: that http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7359 The syntax error seen there was fixed and the result is: http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7361
The same tests was done on legacy kernel 3.4.111 modifying fex file and the result is the same: http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7265 Best regards Chris On Wednesday, May 4, 2016 at 4:19:20 PM UTC+3, Olliver Schinagl wrote: > > Hey Christo, > > On 04-05-16 15:07, Christo Radev wrote: > > Hi Olliver, > > I have already test it a few weeks ago and definitely can say that 8-bit > bus did not work on A20-Olinuxino-Lime2-eMMC with mainline kernel. > See may post here > <http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7361> > . > > I saw, but you forgot to define the pins for 4.x :) > > See my patch from earlier: > http://lists.infradead.org/pipermail/linux-arm-kernel/2015-September/368887.html > > Olliver > > > Best regards > > Chris > > On Wednesday, May 4, 2016 at 3:52:17 PM UTC+3, Olliver Schinagl wrote: >> >> Hey Radoslav, >> >> On 04-05-16 14:30, Radoslav Kolev wrote: >> > 2016-05-03 10:25 GMT+03:00 Chen-Yu Tsai <we...@csie.org>: >> >> On Tue, May 3, 2016 at 3:21 PM, Olliver Schinagl <oli...@schinagl.nl> >> wrote: >> >>>>> + bus-width = <4>; >> >>>> Only 4 bits?
