Blaze omapfb failed to setup omapfb with HDMI

nidiya hui

Other Parts Discussed in Thread: 4430

Hi all,

I use blaze 4430 ES2.2 board, and remove the LCD panel. I can't get the HDMI work with Android 4.0. I follow omappedia to build u-boot, xloader, kernel and ASF file.

http://www.omappedia.org/wiki/L27.IS.1_OMAP4_Icecream_Sandwich_Release_Notes

The kernel can't setup framebuff. How to make the HDMI work when there is no other VIDEO devices?

Try the following patch. It will help to cross one step.
I still have some problems with HDCP key loading error.

It looks like when hdmi panel is default and connected at boot, both hdmi_hotplug_detect_worker and omapfb_init_display are trying to enable the display panel. 
This seems to be design issue.

Hi Navaneetha,

Thanks for you reply,it solvd my "omaplfb: OMAPLFB_Init: OMAPLFBInit failed" problem.But i have another issue as below:

omapfb omapfb: failed to apply dispc config
cannot apply mgr(lcd2) on inactive device
omapfb omapfb: failed to apply dispc config

Hi Tommy,

Glad that the patch helped you. are you able to see anything on screen? at least the android splash screen?

You will be able to find fb0 and fb1 under /dev/graphics/

I guess the manager for lcd and lcd 2 should not be a problem as HDMI doesn't use them, It uses digital channel instead.

Br,

Navaneetha

Hi Navaneetha,

Thanks for patch and your reply,i set the hdmi as default device and the display always "blank screen" and when i entered system, i can see dev/graphics/fb0 and dev/graphics/fb1 node.

I guess there is some issue in the bootargs,i use the bootargs like GB filesystem as below:

#define CONFIG_BOOTARGS "console=ttyO2,115200n8 androidboot.console=ttyO2" \
" mem=456M@0x80000000 mem=512M@0xA0000000" \
" root=/dev/mmcblk0p2 rw rootdelay=2 init=/init" \
" vram=32M omapfb.vram=0:16M" \
" omapdss.def_disp=hdmi consoleblank=0"

Whether if the VRAM should change? or other parameters?

Regards

Tommy

Hi Tommy,

can you enable omapdss and omapfb logs?

Steps to enable dss logging

Change your boot args to:

#define CONFIG_BOOTARGS "console=ttyO2,115200n8 androidboot.console=ttyO2 consoleblank=0" \
" mem=456M@0x80000000 mem=512M@0xA0000000" \
" root=/dev/mmcblk0p2 rw rootdelay=2 init=/init" \
" vram=32M omapfb.vram=0:16M" \
" omapdss.def_disp=hdmi omapdss.debug=y omapfb.debug=y"

check if CONFIG_OMAP2_DSS_DEBUG_SUPPORT is set in you defconfig file
