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:

include/asm-arm/clock.h

add one new enumerated PIXEL_CLK

cpu/arm_cortexa8/mx53/generic.c

add one new case of the switch (clk_type) in the int clk_config(...)

add the follow lines at the end of the file

board/freescale/mx53_smd/mx53_smd.c

insert the follow lines between #ifdef CONFIG_ADV_SOM_CMX53 and #else

replace the part of the ... ipuv3_fb_init ... clk_config ... by the following:

• u-boot environment variable

set bootargs_base as below:

setenv bootargs_base 'setenv bootargs console=ttymxc0,115200 ldb=single,di=1,ch0_map=JEIDA,ch1_map=JEIDA video=mxcdi0fb:RGB24,G070Y2 di1_primary,bpp=24'

• linux kernel

arch/arm/mach-mx5/mx53_smd.c

insert the following lines into static struct struct fb_videomode ldb_modefb[] (or modify the existed "G070Y2") :

IDK-1115R-40XGC1E

• u-boot environment variable

set bootargs_base as below:

setenv bootargs_base 'setenv bootargs console=ttymxc0,115200 enable_wait_mode=off video=mxcfb0:dev=ldb,1024x768M@60,if=RGB24 ldb=sin0'

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
                       timing0: lti370ln01 {
                               clock-frequency = <148500000>;
                               hactive = <1920>;
                               vactive = <544>;
                               hback-porch = <70>;
                               hfront-porch = <70>;
                               vback-porch = <200>;
                               vfront-porch = <200>;
                               hsync-len = <140>;
                               vsync-len = <185>;
                       };

Calculating Timings parameter Check your panel Timing table Example : samsung 37 inch panel

(1)clock-frequency --> Clock (MHz)

(2)hactive --> Horizontal Active Display Period

(3)vactive --> Vertical Active Display Period

(4)hback-porch + hfront-porch + hsync-len (Total) = Blanking = Horizontal Total - Horizontal Active Display Period

(5)vback-porch + vfront-porch + vsync-len (Total) = Blanking = Vertical Total - Vertical Active Display Period

U-boot command ( Must be add "video=mxcfb1:off")

     setenv mmcargs setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} video=mxcfb0:dev=ldb,1920x540M@60,if=RGB24 video=mxcfb1:off

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));
               clk[IMX6QDL_CLK_LDB_DI1_SEL]      = imx_clk_mux_ldb("ldb_di1_sel", base + 0x2c, 12, 3, ldb_di_sels,      ARRAY_SIZE(ldb_di_sels));

How to control the screen blanking

to blank the primary display

# echo 1 > /sys/class/graphics/fb0/blank

to unblank the primary display

# echo 0 > /sys/class/graphics/fb0/blank

to set auto-blanking timeout seconds
The default linux framebuffer support will blank a console after 600 seconds of no activity.

kernel space

specify kernel parameter 'consoleblank=<n>' (where <n> means timeout seconds) in u-boot's parameter, bootargs_base

user space

use the command, setterm

5. You can download following file. Then put the decompressed files into the uboot-imx6/arch/arm/include/asm/ path

File:ioNew_h.zip

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

File:adv_logo.zip

The following operations demonstrate how to customize one 800*480 boot logo for ROM-3420 with imx6LBV2210.

• get one 800*480 8bpp BMP ready, or convert from PPM to BMP file

$ ppmtobmp -bpp=8 uboot_logo.ppm > uboot_logo.bmp

• convert to C file

$ xxd -i uboot_logo.bmp > uboot_logo.c

• create new u-boot-2009.08/board/freescale/common/adv_bmp_reversed_800x480.c

• u-boot-2009.08/board/freescale/common/Makefile

• Check the ADV loader version. For example: The ADV loader version is V2.210 in the following message

 

• u-boot-2009.08/board/freescale/mx6q_rom-3420/mx6q_rom-3420.c

1. If ADV loader version of the device is less than the V.2350 version, modify the content as follows:

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
