Dear

    I floow the step: http://omappedia.org/wiki/4AI.1.4_OMAP4_Icecream_Sandwich_Panda_Notes

   the pandaboard can boot up....everything is ok.....

   but there are no sound for headset (Patching for Pandaboard have done),also I have tried to connect to bluetooth,it has no sound either.....

   how can I solve it ?

   And I see it boot slow.

   it have to wait 10 seconds in uboot ,before you can see kernel   @ 80008000 (3868992)  .......

  I see the bootcmd is booti mmc0  so i change that:

  mmcinit 0;mmc 0 read 0x4800 80008000 0x1000;booti 80008000;

  however it hang; the log is

  Starting kernel ...

  undefined instruction
   pc : [<80008004>]    lr : [<80e9a420>]
 sp : 80e3f9d8  ip : 00000004  fp : 80ea84e4

    Hi Sunny,

    About the audio:

    I have look into the audio hal, and if you are using the hdmi port it will send the audio only there, but if you are using the dvi port it will send it to the handsfree port of the audio chip. That port is available in the expansion connector J6. The audio jack connector goes to the handset of the audio chip, so if you want to get the audio there always you will need to modify the audio hal.

    Look at file mydroid/device/ti/common-open/audio/audio_hw.c

    About the boot up:

    I don't see it taking so much time, did you modify something?. Try reverting all changes, reapply and build again.

    I found that the boot up is something about the sd card.......  when i use sandisk it has to wait 10 seconds..... when i use kingston it only use 4 seconds....

    but i want to ask that why i change the bootcmd to

    mmcinit 0;mmc 0 read 0x4800 80008000 0x1000;booti 80008000;

    and it can't work?

    and also i want a sound for bluetooth....how can i do it ?

    i have tried tinymix to change the config ....it does...

    but after a monent.... it backs to original
