Linux Kernel Hangs at start up

Hi,

I am using TI OMAP3 Android Froyo prebuilt image over Mistral's EVM kit.

While booting from SD card the linux kernel hangs right after uncompressing.

    What is the evm revision you are using? The TI Android Devkit is meant for omap3evm rev G.

    You have also not mentioned  if you are using Froyo devkit 2.0 or 2.2

    Did you populate the SD card using the mkmmc-android script provided with the prebuilt images? The bootargs don't look right.

     

    BTW, you can ask android questions at the E2E forum for android@ http://e2e.ti.com/android

    Shishir,

    I think kernel is crashing very early stage of boot process, way before mounting filesystem. Your bootargs doesn't seems to correct, "mem=" option is not specified, try specifying mem= option.

     

    Thanks,

    Hi Guys,

    You were right about the mess up in the environment variables.

    These two worked for me to get the kernel booting. I copied them from older version android build provided by Mistral.

    setenv bootcmd 'mmc init;fatload mmc 0 0x81c00000 uImage;bootm 0x81c00000'
    setenv bootargs 'console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw rootdelay=1 init=/init videoout=omap24xxvout omap_vout.vid1_static_vrfb_alloc=y mem=128M'

    Also I was trying to make the Dev Kit 2.0 Froyo going over omap3evm Rev D. Whereas it only supports Rev G.

    Probably it's time to ask my manager for hardware upgrade. Which is least likely to happen.

    Anyways guys thanks for your prompt responses.

    Cheers,

    Shishir

    Hi All,

    Back Again.

    Just tasted the first success of being able to run Dev Kit 2.0 Froyo over my omap3evm Rev D.

    I was getting error sayin

    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 PVR_K: (FAIL) SGXInit: Incompatible HW core rev (10003) and SW core rev (10201).

    All it required was to recompile the kernel with option OMAPES=2.x and Bingo !!!

     

    Cheers,

    Shishir

    Hello, 

     

    I will post my question here such as not to flood the forum with not very useful  topics.

    My question : Is there any way of booting any kind of Android distribution on an OMAP3 EVM Rev D?

    I see that obviously someone managed to do it but as far as i've seen he is the only one. I tried booting the Prebuilt images, and that doesn't seem to work for me. i tried recompiling the system but i have an error:
