- The following operations are performed with RSB-4210 and BSP version 20120705 (i.MX5).
- u-boot
- get u-boot-2009.08_V1.1.patch and use it to patch by the following commands:
$ cd ${BSP_20120705_BASE}/source/u-boot-2009.08/
$ patch -p1 < ../u-boot-2009.08_V1.1.patch
- include/asm-arm/clock.h
- add one new enumerated

- cpu/arm_cortexa8/mx53/generic.c
- add one new case of the
switch (clk_type)in theint clk_config(...)
- add one new case of the
case PIXEL_CLK:
if (config_pixel_clk(ref, freq))
return -1;
break;
-
- add the follow lines at the end of the file

Dual Channel LVDS Panel
Calculating Timings parameter of LVDS Panel SOP OS: Yocto 1.8 Modify imx6qdl-advantech.dtsi Step1: In ldb parameter, add parameter --> split-mode; /* dual-channel setting *
&ldb {
ext_ref = "true";
status = "okay";
split-mode; /* dual-channel setting */
Step2: In lvds-channel@1, change [crtc = "ipu1-di1";] to [crtc = "ipu1-di0";]
lvds-channel@1 {
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
/* crtc = "ipu1-di1"; */
crtc = "ipu1-di0"; /* dual-channel setting */
status = "okay";
Step3: In display-timings native-mode = <&timing0>, Delete the other panel parameter.Add" LTI370LN01 " Parameter
//Dual channel panel

Need to change clock source, so we modify dts file.
imx6q-rom3420-a1.dts is taken as an example:
Add the code as below to dts file
&clks {
fsl,ldb-di0-parent = <&clks IMX6QDL_CLK_PLL5_VIDEO_DIV>;
fsl,ldb-di1-parent = <&clks IMX6QDL_CLK_PLL5_VIDEO_DIV>;
};
If produst is i.MX6QP , we have to modify arch/arm/mach-imx/clk-imx6q.c as below
(It's just a workaround solution)
//if (cpu_is_imx6q() && imx_get_soc_revision() == IMX_CHIP_REVISION_2_0) {
// clk[IMX6QDL_CLK_LDB_DI0_SEL] = imx_clk_mux_flags("ldb_di0_sel", base + 0x2c, 9, 3, ldb_di_sels, ARRAY_SIZE(ldb_di_sels), CLK_SET_RATE_PARENT);
// clk[IMX6QDL_CLK_LDB_DI1_SEL] = imx_clk_mux_flags("ldb_di1_sel", base + 0x2c, 12, 3, ldb_di_sels, ARRAY_SIZE(ldb_di_sels), CLK_SET_RATE_PARENT);
//} else {
/*
* The LDB_DI0/1_SEL muxes are registered read-only due to a hardware
* bug. Set the muxes to the requested values before registering the
* ldb_di_sel clocks.
*/
disable_anatop_clocks();
init_ldb_clks(np);
clk[IMX6QDL_CLK_LDB_DI0_SEL] = imx_clk_mux_ldb("ldb_di0_sel", base + 0x2c, 9, 3, ldb_di_sels, ARRAY_SIZE(ldb_di_sels));

How to set display in u-boot command
Set HDMI in u-boot command mode is taken as an example:
| # setenv mmcargs setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:off video=mxcfb2:off;boot |
Set LVDS in u-boot command mode is taken as an example:
| # setenv mmcargs setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} video=mxcfb0:dev=ldb,800x480M@60,if=RGB24 video=mxcfb1:off video=mxcfb2:off;boot |
Set VGA in u-boot command mode is taken as an example:

- 5. You can download following file. Then put the decompressed files into the uboot-imx6/arch/arm/include/asm/ path
You can refer to Setting_up_SDK to setup environment for building u-boot image
After you patch file, you need to build u-boot image(Example:ROM-3420 DDR 1G)
- 1. Source environment(Example: Toolchain path:/opt/poky/2.1/)
source /opt/poky/2.1/environment-setup-cortexa9hf-neon-poky-linux-gnueabi
- 2. Build ROM-3420 1G u-boot image
make mx6qrom3420a1_1G_defconfig make -j4
Generate u-boot logo image
- For example: You can use picture editor tool(Photoshop) to generate a 800x480 u-boot logo image(16 bit BMP file)
- 1. U-boot logo file format
File name: adv_logo_800x480_16bit_rgb565.bmp Resolution: 800x480 Depth: 16 Bit BMP Advanced Modes: R5 G6 B5
- 2. Open original u-boot logo file by Photoshop tool
- 3. Save the new file
- 4. New file name:adv_logo_800x480_16bit_rgb565.bmp
- 5. Choose the type of file and press "OK" button to save the file
- Copy u-boot logo file(adv_uboot_logo.bmp) to linux OS(Example: Ubuntu), then produce a u-boot logo file that will actually be used
dd if=adv_logo_800x480_16bit_rgb565.bmp of=adv_logo_800x480_16bit_rgb565_new.bmp bs=1 skip=72 sync
- You can get a u-boot logo file by following link
Upload u-boot image and u-boot log image to eMMC by mgtool
- 1. Modify ucl2.xml file

- 2. Modify cfg.ini file
[LIST] name = ADV u-boot
- 3. Copy "u-boot_crc.bin.crc", "u-boot_crc.bin" and "adv_logo_800x480_16bit_rgb565_new.bmp" files to "3420A1LIVXXX_1G_mfgtools\Profiles\Linux\OS Firmware\files" folder
- 4. Finally, you can refer to Mfgtool to update u-boot image and u-boot logo image

How to customize Android logo
The following operations demonstrate how to customize one Android logo for RSB-4410 with 4410ABV1080.
- replace android/frameworks/base/core/res/assets/images/android-logo-mask.png with the new 24bpp PNG file
How to modify dts file for setting different framebuffer
Example: Because there is one ipu in i.MX6 SOLO,we set LVDS and HDMI as our default display.
If we want to change HDMI and VGA as our default display ,we have to modify and re-compile dts file.
imx6dl-rom5420-b1.dts default as below:
&lcd {
pinctrl-0 = <&pinctrl_ipu1_4>;
status = "disabled"
};
&ldb {
lvds-channel@0 {
crtc = "ipu1-di0";
};
lvds-channel@1 {
status ="disabled";
};
};
&mxcfb3 {
status = "okay";
};
mxcfb3 is mapped to lvds (you can check imx6qdl-advantech.dtsi)
We want to change to HDMI+VGA
&lcd {
pinctrl-0 = <&pinctrl_ipu1_4>;
status = "okay";
};
&ldb {
status ="disabled";
};
&mxcfb2 {
mode_str ="1366x768M@60";
status = "okay";
};
Then re-compile dts file and replace
