    Hi lokesh,

    OMAPL137evm has 3 instances of UART  (ttyS0, ttyS1 and ttyS2). Out of these 3, ttyS2 is connected to the serial output. So bootargs should be set to ttyS2.

    Your bootargs says

    bootargs=console=ttyS0,115200n8........

    can you change it to bootargs=console=ttyS2,115200n8 and verify 

    U-Boot>setenv bootargs console=ttyS2,115200n8 noinitrd rw ip=192.168.1.51 root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock mem=32M

    autoload=no
    baudrate=115200
    bootargs=console=ttyS2,115200n8 noinitrd rw ip=dhcp root=/dev/mmcblk0p1 rootfstype=ext2 mem=32M
    bootdelay=3
    bootfile=uImage
    dnsip=192.168.5.1
    ethact=DaVinci-EMAC
    ethaddr=00:0e:99:02:fc:ae

    and bootcmd set as 'bootm 0xc0700000 but still it gets stuck up at

    Uncompressing Linux...

     

    I have been able to load the MVista trial version of linux after building and even directly available image and that works fine I am able to login and tried simple Hello world tooo

    Even sometime ago I had loaded readily available image of angstrom linux and I could reach the point of loging in ... but when I  try for a build from the kernel from www.kernel.org.. (tried 2.6.39.1 and 2.6.34.9  versions)  its stuck up at this point or gives uncompression error and system halt message.

    Suggestions and help welcomed!!
