Hi Experts,

The HDMI display is not working with the IMX 6 SL EVK board, when tried with the demo images of Lollipop 5.1.1

The command line arguments in bootup logs are as follows:

use boot.img command line:

        console=ttymxc0,115200 init=/init androidboot.console=ttymxc0 androidboot.selinux=disabled panel=hdmi androidboot.hardware=freescale ad

switch to ldo_bypass mode!

   Using Device Tree in place at 83700000, end 8370bed1

Hi lyfsci

One good news for you. Android 4.0.4 have patch for HDMI. From this Android_Release_Notes_13.5.0-GA.01.pdf document below line they mentioned.

device/fsl/ -- 0001-ENGR00230967-Set-default-panel-as-HDMI-when-none-ein.patch  -- Regular update

I'm not sure about this android version. In this version also i used e-INK display. You may try this version android, it may help full for you.

Hi Aravinth,

Thats really great help.

But I am not able to find either the repo or guidelines of the same from the link i.MX 6 Series Software and Development Tool|NXP

Could you specify where I could download the patches and link. If you have one could you kindly attach here ?

Hi lyfsci

i did some projects in both SL EVK and sabresd (Quad and Dual). From my experience LCD only we used for SL EVK. But sabresd related projects we can use both LCD and HDMI. And also patches not there. May be freescale guys they may have.

From my suggestion to bring LCD display, It's a possible and quick solution.

If you have sabresd, then you can use HDMI.

Hi lyfsci

I suggest some debug procedure to you, check the following things and add corresponding response log.

1) Above reply i mentioned some env steps,

    i need a uboot environment from after did the above replied env steps.

2) Check hdmi detected or not..?

Check the cable state:

root@freescale /$ cat /sys/devices/soc0/soc.0/20e0000.hdmi_video/cable_state

plugin

After cable removed state:

root@freescale /$ cat /sys/devices/soc0/soc.0/20e0000.hdmi_video/cable_state

plugout

3) If it's shows PLUGIN, Manually dump image into HDMI.

4) From above comments you mentioned below args:

      video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32

Most of hdmi have 24bpp, you replace below args,

video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24

After did this changes again you try the above 2 and 3 debug procedure. You should follow all the steps in above mentioned order.

Best of luck!

Hi Aravinth,

Thanks for the reply. I tried the steps specified by you.

Result of Step 1:

The env variable is saved and it remains same before and after.

Result of Step 2:

There is not path "/sys/devices/soc0/soc.0/20e0000.hdmi_video/cable_state" exist in the system.

I could only see "/sys/devices/soc0/soc.1/....". There is no HDMI related sys path.

The HDMI display is initially showing "ANDROID" in black terminal screen when kernel image started. But it goes dummy after init.rc and other android framework initialization. Also the monitor doesn't sleep which indicates some HDMI signal is going but there is no display.

Result of Step 4:

I tried but still there is no change in behavior.

Hi lyfsci

   Thanks for your response.

In this Lollipop 5.1.1 SL EVK doesn't support HDMI interface. In android Release note (chapter 4 - Features) SL EVK support LCD pannel only. So HDMI support freescale doesn't provided. So can use LCD alone.

Aravinth

Hi aravinthkumarjayaprakasam​,

Thanks for rightly pointing it out. I have been looking for this for long time.

Could you recommend how to enable the same.

Hi Deactivated user​ CarlosCasillasgusarambulanikjedrzejewski

Could you confirm the same statement here.

In this Lollipop 5.1.1 SL EVK doesn't support HDMI interface. In android Release note (chapter 4 - Features) SL EVK support LCD pannel only. So HDMI support freescale doesn't provided. So can use LCD alone.

I don't have LCD panel but needs to bring up with the HDMI output. What is the latest android release with HDMI output or any patch to enable it in existing demo release ?

It would be great to know the android version being shown as demo in the video Get Started with the i.MX 6SoloLite Evaluatio|NXP ...

Hi lyfsci

Demo images straight away it should work.

Can you try the below command in uboot,

=> env default -f -a

=> env save

=> reset

Have you tried the latest Lollipop 5.1.1.2 boot image in the IMX 6 Solo Lite with HDMI daughter card ?

If so could you advice on where it goes wrong ?

Hi aravinthkumarjayaprakasam​,

Any advice on the above problem.

May I know whether are you able to successfully boot up with the HDMI cable and Android 5.1.1.2_ga for IMX 6 SL ?

Lyf

Hi,

Have you verified that you are writing the bootargs specifically for the Android version that you are using? I have attached the Android Quick Start Guide document for L5.1.1_2.1.0-ga BSP release for your reference. Besides, you should ensure that the MCIMXHDMICARD is properly connected before botting up the board, and should be placed on the “LCD EXPANSION PORT” header (J13) and not on the “EPDC EXPANSION PORT” header.


Hope this will be useful for you
Best regards!
/Carlos

Hi Carlos,

I had verified the connection of HDMI LCD expansion port, which is working fine with the default Android 4.0.1 image shipped with the board.

When I tried to boot up with the demo image for the Solo EVK then it is not working. I am giving the commands as per the Quick start guide.

5.4 Booting with single display: LCD display

When the Android system image is programmed and the Boot Switch(es) is configured, the system is ready to be powered on.

In the U-Boot prompt, set the U-Boot environment variables as shown below:

U-Boot > setenv bootcmd boota mmc1

U-Boot > setenv bootargs console=ttymxc0,115200 init=/init androidboot.console=ttymxc0

consoleblank=0 androidboot.hardware=freescale

U-Boot > saveenv

With the settings above , the Android platform does not start the shell console. It enables the default Android selinux and

dm_verity security features, which restrict users to change the system and detect the system's information. To avoid this,

"androidboot.selinux=disabled" and "androidboot.dm_verity=disabled" need to be appended to the U-Boot's bootargs. Boot

environment variables are as follows:

U-Boot > setenv bootcmd boota mmc1

U-Boot > setenv bootargs console=ttymxc0,115200 init=/init androidboot.console=ttymxc0

consoleblank=0 androidboot.hardware=freescale androidboot.selinux=disabled

androidboot.dm_verity=disabled

U-Boot > saveenv

Also I am not able to see the specific boot arguments for HDMI port in the Quick start guide. I assume the boot arguments are same for the LCD and HDMI port.

Also I could see for other platforms (.MX 6QuadPlus/6Quad/6DualLite SABRE) there is an explicit mention of boot arguments for HDMI based boot.

For example,

4.4.2 Booting with single display: HDMI display

To boot from SD, set the U-Boot environment variables as shown below:

U-Boot > setenv bootcmd boota mmc1

U-Boot > setenv bootargs console=ttymxc3,115200 androidboot.console=ttymxc3 consoleblank=0

vmalloc=400M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off

video=mxcfb2:off video=mxcfb3:off androidboot.hardware=freescale cma=320M

U-Boot > saveenv

With the settings above, the Android platform does not start the shell console. It enables the default Android selinux and

dm_verity security features, which restrict users to change the system and detect the system's information. To avoid this,

"androidboot.selinux=disabled" and "androidboot.dm_verity=disabled" need to be appended to the U-Boot's bootargs. Boot

environment variables are as follows:

U-Boot > setenv bootcmd boota mmc1

U-Boot > setenv bootargs console=ttymxc3,115200 androidboot.console=ttymxc3 consoleblank=0

vmalloc=320M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off

video=mxcfb2:off video=mxcfb3:off androidboot.hardware=freescale cma=384M

androidboot.selinux=disabled androidboot.dm_verity=disabled

U-Boot > saveen
