HDMI output

Hi Dan,

Could you please let me know what is the exact mode you selected on TV instead of Auto to get it full screen? Please provide more details.

How about testing it using other HDMI TV? Did you see similar results?

Thanks & Best Regards,

Venkat

Hi Venkat,

Yes, I tried different HDMI TVs, the result is same, we can't see the total page from TV, it's biger than the TV screen, there will be edge lose.

On some TV, I need to set the Wide configurtion to Normal rather than Strech , while on others I need to set screen mode to PC rather than auto.

Best Regards,

Dan

Are you using the Hardware Compositor HAL? If so what are the values of the following 3 properties?

persist.hwc.docking.enabled

persist.hwc.mirroring.enabled

Hi Matthew,

We choose blaze as reference, except ro.sf.lcd_density was set to 160 from 240, there is no other customzation setting for these xxx, just keep default setting, that's to say:

persist.hwc.docking.enabled=1
persist.hwc.mirroring.enabled=1
persist.hwc.mirroring.region=0:0:1280:720

I don't know if you want mirrored or docking mode, but I do know at least one of those needs to be zero. Right now you are in docking mode since they are both set to "1"

as far as the region, that should be set to the resolution of your panel, presuming you want to clone the entire UI at LCD aspect and letter boxed on the HDMI. What exactly are your HDMI requirements?

Hi Matt,
I'm not very clear what you mean by "HDMI requirements". Our board has no LCD, just only output to TV through HDMI, below is my setting for HDMI timings:
.panel = {
  .hdmi_default_cea_code = 4,
  .timings = {
   .x_res = 1280,
   .y_res = 720,
   .pixel_clock = 74250,
   .hsw = 40,
   .hfp = 110,
   .hbp = 220,
   .vsw = 5,
   .vfp = 5,
   .vbp = 20,
  },
        },

Thanks & Best Regards,

Dan

Okay, my misunderstanding. Have you tested it with and actual HDMI monitor? What kind of TV are you using, please explain the dongle. With the unknown hardware in the mix I cannot answer your question.

Hi Matt,
Our dongle just has the micro-SD, one HDMI, one usb port for power supply, one usb port for OTG, no camera or LCD and other device, but all the chips (CPU, PMIC, wifi, flash, DDR and so on) we use are same as your blaze reference.
The TV has nothing special, all have tested with other STB box or OTT and works fine.

Thanks & Best Regards,
Dan

Dan,

I don't think your timings are correct. You want CEA mode 4 which is HD @ 60Hz? Then the numbers below that don't work. Can you explain how you calculated all of them? Can you show me a screenshot? I have to have more detail from you before I can answer this.

Also your board file would be nice to have, as well as your boot args for enabling HDMI as default display. 

Hi Matt,
The HDMI timeing is set as refer to your VESA resolution examples from Bootargs for enabling display - OMAPpedia.htm file, I have tried 720P {4.1280,720,74250,40,110,220,5,5,20} and 1080P {16,1920,1080,148500,44,88,148,5,4,36}, the 1080P cann't be shown normally, it will be dark after one second show.

Below is the image, you can see the four red frame just can not show the total icon:

Thanks & Best Regards,
Dan

Hi Matt,
I haven't change any HDMI setting, for your guys told me that 4AI.1.7 have alraedy support output to TV automactically.

Well, I am surprised that even works. Yes $AI.1.7 does support HDMI ad the default or only display without patching, but it isn't automatic, there are some configuration considerations.

You have to at least have 'omapdss.def_disp=hdmi' as a boot arg.

'omapfb.fb_opt=0,1920,1080' Will increase the size of the frame buffer for 1080p, This option is recommended even if you default to 720p.

The next question is what board files are you using and how are you configuring the display. You do not enter in the timings, those are normally read from the EDID. I will point you to the board-44xx-tablet.panel.c file as and example of how your board file needs to be constructed for HDMI as the only and default display. I ask again, are you using your own board file? If so can I see it. You have to be more specific for me to help you.

Hi Matt,
We take balze as reference, that's to say our board file is board-4430sdp.c, in order to let HDMI as default output, we do modify to sdp4430_dss_devices[] and sdp4430_dss_data as below:
static struct omap_dss_device *sdp4430_dss_devices[] = {
 //&sdp4430_lcd_device,
 &sdp4430_hdmi_device,
};

static struct omap_dss_board_info sdp4430_dss_data = {
 .num_devices = ARRAY_SIZE(sdp4430_dss_devices),
 .devices = sdp4430_dss_devices,
 //.default_device = &sdp4430_lcd_device,
 .default_device = &sdp4430_hdmi_device,
};

Thanks & Best Regards,
Dan

That might work, but HDMI DD is really only supported on the tablet. You should not enter all the timings in the board file, but allow the EDID to drive that. I would point you to the table board files as a reference not the blaze sdp board file. If you look in the tablet board files you will see how the omapdss.default_display=hdmi changes up the data structures as well has how the panel data structure is filled in to support this.

Hi Matt,
So could you please teach me how to add omapdss.def_disp=hdmi to boot arg? I tried to save this parameter to bootargs @ u-boot as below but it doesn't work, after boot into kernel or reboot the board, the bootargs was reset to "console=ttyO2,115200n8 mem=456M@0x80000000 mem=512M@0xA0000000 init=/init vram=10M omapfb.vram=0:4M"

Dan,

"saveenv" doesn't work on these releases, as there is no longer an "env" partition on the eMMC.  However, you could use "setenv bootargs 'console= ...." and then type "boot".  You could also change the bootargs in the kernel defconfig file.  For Blaze / Blaze Tablet, this file is /kernel/android-3.0/arch/arm/configs/blaze_defconfig.  Modify the line:

CONFIG_CMDLINE="console=ttyO2,115200n8 mem=1G vmalloc=768M androidboot.console=ttyO2 omap_wdt.timer_margin=30"

Regards,
Gina 

If you are booting from emmc, you can also use the umulti2.sh script. You add any addition boot args in that script and then used the script to rebuild boot.img, then you flash it to the emmc.

Hi Matt,

 I add omapdss.def_disp=hdmi to the bootargs in /kernel/android-3.0/arch/arm/configs/blaze_defconfig, then choose blaze_tablet as reference and clean then rebuild the whole project,result is same, we still can't see the whole menu on the four corner.

Thanks & BR.

Dan

Dan,

You are going to have to put alot more effort into giving me the information I need to solve your problem. I cannot diagnose a problem without adequate information.I need to see your board file and I would like to see a complete kernel log from start up.
