Hi Olliver, I try to build Armbian with kernel 4.5.0-rc6 by adding the patch as discussed here . In addition I have to add following as well: diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 95c1923..9d6cfa8 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -695,6 +696,7 @@ dtb-$(CONFIG_MACH_SUN7I) += \ sun7i-a20-olimex-som-evb.dtb \ sun7i-a20-olinuxino-lime.dtb \ sun7i-a20-olinuxino-lime2.dtb \ + sun7i-a20-olinuxino-lime2-emmc.dtb \ sun7i-a20-olinuxino-micro.dtb \ sun7i-a20-orangepi.dtb \ sun7i-a20-orangepi-mini.dtb \ to be able to compile the new sun7i-a20-olinuxino-lime2-emmc.dts file. After booting I have renamed it to sun7i-a20-olinuxino-lime2.dts and reboot lime-eMMC board. Unfortunately, I get some error messages: root@lime2:~# dmesg | grep mmc [ 0.000000] Kernel command line: console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_no_mali_mem_reserve sunxi_fb_mem_reserve=16 hdmi.audio=EDID:0 disp.screen0_output_mode= 1920x1080p60 panic=10 consoleblank=0 enforcing=0 loglevel=1 [ 3.721024] sunxi-mmc 1c0f000.mmc: Got CD GPIO [ 3.758926] sunxi-mmc 1c0f000.mmc: base:0xf08dc000 irq:26 [ 3.759832] sunxi-mmc 1c11000.mmc: allocated mmc-pwrseq [ 4.528643] sunxi-mmc 1c11000.mmc: fatal err update clk timeout [ 4.535700] mmc0: host does not support reading read-only switch, assuming write-enable [ 4.538253] mmc0: new high speed SDHC card at address 0002 [ 4.539066] mmcblk0: mmc0:0002 00000 3.70 GiB [ 4.540959] mmcblk0: p1 [ 4.548773] sunxi-mmc 1c11000.mmc: base:0xf08f2000 irq:27 [ 6.418686] sunxi-mmc 1c11000.mmc: fatal err update clk timeout [ 6.600359] EXT4-fs (mmcblk0p1): mounted filesystem with writeback data mode.
