Hi,everyone!
I'm a newcomer.I've really puzzled over the question for a long time.I've tried to rebuilt my Uimage ,and reinstalled my ubuntu 10.04,but still,it stucks here:"uncompressing linux..."
I've set the board starting from NANDFLASH.my cpu is OMAPL138,and my board is SEED_DEC138,and here is my uboot environment:
U-Boot > printenv
bootdelay=3
baudrate=115200
bootfile="uImage"
ethaddr=0a:c1:a8:15:fa:c0
ethact=
ip=10.108.51.101
filesize=F60000
fileaddr=C1180000
serverip=192.168.253.77
ipaddr=192.168.253.123
bootargs=mem=128M console=ttyS0,115200n8 root=/dev/nfs
bootcmd=tftp 0xc0700000 uImage; bootm
stdin=serial
stdout=serial
stderr=serial
ver=U-Boot 2009.01 (Jan 06 2010 - 11:01:54)
the upper red line is a little strange ,I guess it's from my last setting,but I guess it has nothing to do with the problem since the board can download uImage successfully through tftp.
problems occured after I reset the board:
