Hi Your 'bootcmd' is rubbish it seems to have picked up part of a bootargs setting & lost most of the rest of it. I would clean up the uboot settings - for a DM6446 the original settings are: DaVinci EVM # printenv bootargs=mem=120M console=ttyS0,115200n8 root=/dev/hda1 rw noinitrd ip=dhcp bootcmd=setenv setboot setenv bootargs $(bootargs) video=dm64xxfb:output=$(videostd);run setboot;bootm 0x2050000 bootdelay=3 baudrate=115200 bootfile="uImage" stdin=serial stdout=serial stderr=serial ethaddr=00:0e:99:02:57:e1 videostd=pal
Remember of you want to put a '$' or ';' in an uboot variable you have to escape it with the backslash '\' char. The 'videostd' variable is set by uboot depending on a switch setting - ours happend to be PAL. If you want to TFTP a kernel then you need to do the following... setenv ipaddr 172.18.0.222 setenv serverip 172.18.1.34 tftpboot 0x80700000 /tftpboot/uImage bootm 0x80700000 Change ip addresses & kernel names to suit. A quick setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=172.18.0.13:/tftpboot/remote_fs/davinci_6446,nolock mem=120M ..before the 'bootm 0x80700000 will change it to boot via NFS instead of the hard disk Regards Phil Q Phil Quiney, Senior Software Engineer Trinity Convergence Cambridge Business Park Cowley Road Cambridge CB4 0WZ, UK T: +44(0)1223-435536 F: +44(0)1223-435560 www.trinityconvergence.com <http://www.trinityconvergence.com/> ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Panchy Rivas Sent: 01 August 2008 16:00 To: [email protected] Subject: Problem booting DM6446 off TFTP I am having problem booting off TFTP can anyone please help.
