mmc init

fatload mmc ${mmcdev} ${loadaddr} uImage-2.6.37

setenv bootargs root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait mem=200M

bootm ${loadaddr}

After booting, load the drivers:

    Rafael,

    Could you give some steps how to get linux kernel 2.6.37 and dsp on the beagleboard -xm?

    Does this work include the android filesystem?
    Wich DVSDK version did you use?

    Hi Igino,

    First you have to install Angstrom on the SD Card as described here:

    http://www.angstrom-distribution.org/demo/beagleboard/

    Then you have to configure U-Boot to enable the memory area for the DSP, as described in the link above.

    After that you can install DSP tools and packages for BeagleBoard directly in the board using opkg. That’s the way I did, and it worked.

    Hope it helps.
