4AJ.2.x default HDMI display

Hi,

could someone summarize what needs to be done with current 4AJ.2.x to enable HDMI display at 1080p as default display?

This is what I am doing:

Set the bootargs with

./mkbootimg --kernel zImage --ramdisk ramdisk.img --base 0x80300000 --cmdline "omapdss.def_disp=hdmi omapdss.hdmi_options=1920x1080" --board omap4 -o boot.img

Run fastboot.sh with the new boot.img

Boot up the system

Now the cmdline is as an example:

cat /proc/cmdline
console=ttyO2,115200n8 androidboot.console=ttyO2 omap_wdt.timer_margin=30 vmallo
c=496M omapfb.fb_opt=-1,-1,-1,1,1280,720 omapdss.def_disp=hdmi omapdss.hdmi_opti
ons=1920x1080 androidboot.serialno=014E64F00301C00B androidboot.bootloader=U-Boo
t_1.1.4-jenkins-JB_uboot_mr1-294^0

Set the following setprop

# setprop persist.hwc.mirroring.region 0:0:1920:1080

Reboot the system again.

This used to work, but now somehow my monitor cannot detect a signal from the HDMI.

Thanks,
