Hi, I once copied and used your device tree file (thanks for that). Since then, me and another guy from Germany have extended this file.

I thought dropping my current device tree file here would be a good idea, maybe you can use it.
I use MarS Board with OpenELEC/LibreELEC and xbian 4.4 kernel with HDMI audio/video, running really great even with 20GB full hd movies :)

Hi FrankBau ,
PFA,
I want to enable the touch screen in my LCD (St7789s LCD driver IC) and touch controller is is FT6306DMB with MARS imx6 dual cortex A9 Board, when i am connect the pin no 42 & 43 on board side for I2C communication i am not getting any signal on oscilloscope(please refer the image name by LCDPARALLELPORT.png), But when i am connect the pin no 3 & 5 on Expantion Port(J11) in Board side i am getting the some signal on oscilloscope with wrong address(please refer the image ExpantionPort.png ), i am expecting the 0x38 is the correct address, in boot log i am getting the message like" could not detect touch screen -19" could you please help me where i am wrong in this case , how to solve this issue,

Best Regards

Hi,
as many boards (like mine) doesn't have C++ libraries installed by default, I made some little adaptations to devregs.cpp to convert it in C language.

I put converted file here to anyone needs a C binary instead of C++ one.

This binary is based on devregs.cpp in commit fdd9c392f5273d26696315939e0ab893e4cbc6cb.

To compile it using included autoconf, simply place attached .c file in src directory and apply below changes:

diff --git a/configure.ac b/configure.ac

Hi Frank,

I want to interface the LCD (driver is ST7789S is up now )and touch screen(driver is FT6306DMB) with MARS imx6 dual cortex A9 Board, LCD Display is working Fine, But making the Touch Screen(Panel) to work
I added the below code in my imx6q-marsboard.dtb file
// MY TOUCH PANEL CODE
&i2c3 {
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c3>;

compatible = "edt,edt-ft6306", "edt,edt-ft5x06";
reg = <0x38>;
pinctrl-names = "default";
pinctrl-0 = <&edt_ft5x06_pins>;
interrupt-parent = <&gpio2>;
interrupts = <11 2>;
reset-gpios = <&gpio7 13 1>;
};
};
//MY TOUCH PANLE CODE END

        //MY TOUCH PANEL CODE
        edt_ft5x06_pins: edt-ft5x06grp {

    };                
               //MY TOUCH PANEL CODE END

but i am getting the bellow following boot log error and touchscreen probed failed and i enabled i2c driver in kernel also,

Hi Frank,

I am using the Mars Board, For this board i build the "core-image-sato" image,For buliding this image i followed this link

1. (https://github.com/FrankBau/meta-marsboard-bsp/wiki/Setting-up-the-Build-Environment),

2. Then i added QT5 layer to source dir (git clone -b jethro https://github.com/meta-qt5/meta-qt5.git) 3) Then i added the Mars Board layer to source dir (git clone -b krogoth https://github.com/FrankBau
   /meta-marsboard-bsp)

3. Finally i set the "MACHINE=marsboard source setup-environment build"

4. Then i build the image using "bitbake core-image-sato",
   in this case i am succeed to build and run the image on HDMI display without changing any uboot
   parameter,
   Now i am facing some problems they are as given below,

5. when i am recompile the "uImage" without changing anything in source i am getting the "uImage"
   with only 2.1MB of size (but it was actually 5.8MB originally size), for compiling
   in case (i) : "make -j4 uImage" it gives 2.1MB size of uIamge.
   in case (ii): "make -j4 uImage LOADADDR=0x10008000" it gives 5.0MB size of uImage.
   when i am use the case (ii) uImage it is not working, and i set the load address also, it stuck at
   starting kernel....,

6. Now i want to interface this board with "New Heaven Display 5" LCD [hx8257 driver IC]", so i modified some changes in source then i recompile the "imx6q-marsboard.dts" and "uImage" for uImage i use the follwing command "make -j4 uImage LOADADDR=0x10008000" this also gives the same 5.0MB size of uImage, And i use this uImage with setting the Load Address it stuck at starting kernel...

below is the kernel logs:

then i update the "u-boot.imx" also it doesn't help me to solve this issue,

could you please help me to come out this problem,

Thanks in advance

Hi. I'm trying to build and boot an image for my MarS board. I was able to build the core-image-minal and virtual/bootloader using bitbake without any errors, and even deploy the bootloader on the board.

However, I got stuck trying to boot the kernel:

The boot process just stops there. There is some LED activity on the board for a few seconds, but I don't know if it is related to the kernel booting but not outputting anything to the console.

I followed the wiki instructions to the letter, deleted the build dir and then tried again, but with no success. I'm out of ideas. Can you help me? Thanks!

Doing
bitbake image-multimedia-full
fails while linking eglingo-fb_1.0.0.bb recipe and gives following errors

Removing "eglinfo-fb" from IMAGE_INSTALL_append in sources/meta-marsboard-bsp/recipes-images/image-multimedia-full/image-multimedia-full.bb works around this linking error as ellinfo-fb is not built at all.

I am trying to boot the mars board from SD card but It is struck while reading the uboot and kernel image, and i set the boot mode switches both in OFF mode, For building the image ,loading the image and booting, i followed this link completely all steps mentioned in this (https://github.com/FrankBau/meta-marsboard-bsp/wiki), Then i got below is mars board logs
