OMAP3530 EVM boot from SD Card
July 20, 2013 06:40AM
I'm a beginner. I'm using `OMAP3 EVM`. Currently, I'm able to boot via `NFS`. But, I want it to be from `SD card`. I removed the `boot.scr` file while changing it to SD boot. It was booting properly. But, after the line `'Uncompressing Linux...'` it waits for some time and then file system gets loaded directly and asks for login. The so many lines of initialization logs which used to come after the line `'Uncompressing Linux...'` are completely missing. But, the root file system is fully loaded and I'm able to use it as I did previously. So, I tried making the boot.scr file by removing the nfs related arguments alone.

The `boot.scr` commands previously,


    setenv bootargs 'mem=128M console=ttyS0,115200n8 noinitrd rw rootfstype=ext3 ip=dhcp root=/dev/nfs nfsroot=192.168.15.3:/home/mistral/nfsroot,nolock'
    setenv bootcmd 'mmc init; fatload mmc 0 0x80000000 uImage; bootm 0x80000000'
    fatload mmc 0 0x80000000 uImage
    bootm 0x80000000


The `boot.scr` commands now,


    setenv bootcmd 'mmc init; fatload mmc 0 0x80000000 uImage; bootm 0x80000000'
    fatload mmc 0 0x80000000 uImage
    bootm 0x80000000


I haven't modified the `uEnv.txt`. It's contents are,

    bootargs=console=ttyS0,115200n8 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait init=/linuxrc ip=off
    bootcmd=mmc rescan ; fatload mmc 0 81000000 uImage ; bootm 81000000
    uenvcmd=bootd


Now, it has completely stopped booting after the line `'Uncompressing Linux...'`.
Please guide me in where I'm going wrong.

Recently I installed the uboot and davygravy's Rescue V2.8.2for my Pogoplug Mobile, since I am not going to use Pogo's service anymore.
