HDMI Error on I.MX6Q SDB

Question asked by ArcheeW on Dec 19, 2012


   I run android4 on mx6q sdb.

   the BSP : imx-android-r13.4-ga, and patch use :r13.4-ga_sdb_sdp;


  After I set up u-boot cmd as :

    setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60 video=mxcfb1:off video=mxcfb2:off fbmem=28M


   and saveenv ; reset the board.  When I plug the HDMI to VGA connector, the debug serial output:


  fbcvt: 1920x1080@60: CVT Name - 2.073M9

mxc_hdmi mxc_hdmi: same edid


mxc_hdmi mxc_hdmi: same edid


But, the HDMI Monitor show nothing.


Is someone know why!?
