Pandaboard ES stop at: Uncompressing Linux... done, booting the kernel.

[flex...@gmail.com]

Hello everyone. I have just bought a Pandaboard ES and I am trying to run Ubuntu 12.04 on it, with the pre-built package. I do everything following the Quick Guide:http://omappedia.org/wiki/Ubuntu_Pre-built_Binaries_Guide, but I just get 

Uncompressing Linux... done, booting the kernel.

in the end. Help me, please!

This is the output message:

Hi,

If you have LCD TV which contain HDMI or DVI port then using HDMI to HDMI Cable u can see your ported OS on it.
it works fine.
For Getting Console for that go to /boot/boot.script file and change the  bootargs( Booting Arguments ) as follow.

        fatload mmc 0:1 0x80000000 uImage
        fatload mmc 0:1 0x81600000 uInitrd
        setenv bootargs ro elevator=noop console=ttyO2,115200n8 mem=1G@0x80000000 root=/dev/mmcblk0p2 fixrtc splash
        bootm 0x80000000 0x81600000

Then, Install this new bootloaders through command:

    $ sudo /usr/sbin/flash-kernel --update-bootloader

Now, create or modify the below content in respective files:
Check content or create file /etc/flash-kernel.conf

    ->It displays:

        UBOOT_PART=/dev/mmcblk0p1
        ROOT=/dev/mmcblk0p2

Also Create the file /etc/init/tty02.conf, with the following content:

        # ttyO2 - getty
        #
        # This service maintains a getty on ttyO2 from the point the system is
        # started until it is shut down again.
       
        start on stopped rc RUNLEVEL=[2345]
        stop on runlevel [!2345]
       
        respawn
        exec /sbin/getty -8 115200 ttyO2

And Finally Reboot the system.

Thanks a lot! It turns out to be my fault. I just focus on the serial output without using any LCD.

You should add the following lines in panda_defconfig or omap2plus_defconfig,

        CONFIG_DEBUG_LL=y

        CONFIG_EARLY_PRINTK=y

        CONFIG_OMAP_LL_DEBUG_UART2=y

And then you'll see what it's happening..

It happened to me a few times when there was a problem with uImage file - i.e. I implemented changes that had not had a chance to work.

I'd try a different pre-built package or distribution.

http://www.omappedia.com/wiki/PandaBoard_Ubuntu_How-tos by default serial output does not appear on ubuntu prebuilts.
http://www.google.com/search?q=pandaboard+ubuntu+serial+port shows how many times this question keeps popping up :(

I had the same issue a few months ago, and I don't remember exactly, but I think that I tried to switch between the DVI and HDMI conector. Ubuntu don't show any messages when the kernel starts up!!

In the previous solution that I posted you have to compile the kernel from the Ubuntu source code.
