ibox4412 transplant Ubuntu (kernel3.8.13+13.10 from Friendlyarm and odroid)

Successful implementation of friendly/odroid 3.8.13 kernel and 13.10ubuntu porting on Ibox (SD card)

Implementation features:

Wireless Internet, hdmi1080p (audio sync) output, video playback, sound card, touch screen, LCD and other common drivers are fully ported

1, porting the Linux kernel, refer to ibox4412 3.0 and 3.5 kernel, friendly transplant odroid 3.8.13 kernel, content Skip

HDMI-related drivers have three places:

\linux-3.8.13\drivers\media\video\s5p-tv (first place not to participate in compilation, not used)

\linux-3.8.13\drivers\media\platform\s5p-tv (the second kernel driver code is exactly the same as the first one, can be used fully, create 3 FB device nodes and 3 video device nodes)

Drivers need to be configured

static struct I2c_board_info Hdmiphy_info = {i2c_board_info ("s5p_hdmiphy", 0x38),//i2c_board_info (" hdmiphy-exynos4412 ", 0x38),};

And

S5p_i2c_hdmiphy_set_platdata (null); S5p_hdmi_set_platdata (&hdmiphy_info, NULL, 0,  exynos4_gpx3 (7)); S5p_ Hdmi_cec_set_platdata (&hdmi_cec_data);

\\192.168.56.102\workspace\4412\tiny\linux-3.8.13\drivers\gpu\drm\exynos (using the DRM method, only registered a FB5, this is the way the official is friendly by default)

Then copy the contents of the Udisk into the SD card making EXT4 partition.

3, in order to support the HDMI output, need to set

Etc/x11/xorg.conf

# x.org X Server configuration file for xfree86-video-malisection "Device" Identifier "Mali-fbdev" Driver "Mali" Option " Fbdev "           /dev/fb5" option "DRI2"            "true" option "Dri2_page_flip"  "false" option "Dri2_wait_vsync" "true" Option "  ump_cached"      "true" option "  Ump_lock"        "false"        option  "G2d_device" "/dev/video2"        option  "G2d_enable" "false" option "DPMS" "false" endsectionsection "screen" Identifier   "Default screen "Device       " Mali-fbdev "defaultdepth 24EndSectionSection" DRI "Mode 0666EndSection

Set according to the node condition
