You have a 'setenv=bootcmd nboot 80700000 0 a0000' which is nonsense. I think that should have been bootcmd=nboot 80700000 0 a0000 The reason it does not boot is because you have set 'bootcmd=bootm' As there is nothing in memory you get the bad magic number. If you set the bootcmd to nboot 80700000 0 a0000, I think it should at least try to boot. You then need to sort out the bootargs, as previously posted 'nfsroot=10.65M' is not right, it should be an IP address & path to the NFS root filesystem on your server. I guess this is either a cut'n'paste issue, or perhaps the terminal emulator is not wrapping long lines. Also you cannot put u-boot variables into the bootargs variable, they do not get expanded and the kernel will not know how to handle $(nfsroot) and $(rootpath). There is a 'trick' to do this that has been used on the DM6446..... bootcmd=setenv setboot setenv bootargs $(bootargs) video=dm64xxfb:output=$(videostd):format=component davinci-vpfe.device_type=1;run setboot;bootm 0x2200000 All this did was allow the $(videostd) variable to be picked up at boot time - the 'run setboot' was the trick that caused bootargs to be reset with the expanded variables. I was going through this valuable trick , and was interested in getting the ethaddr env variable expanded so that I can get the MAC address in the driver. I tried doing this after looking at the above example, just to check if the ethaddr gets expanded 1. set bootcmd setenv setboot setenv bootargs console=ttyS0,115200n8 ro noinitrd rw ip=dhcp eth=$(ethaddr) mem=100M;run setboot ## Error: "setboot" not defined Can you please tell me, what went wrong here or what would be the correct way to achieve this? regards -Nitin 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 ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Viral Sachde Sent: 29 September 2008 07:14 To: Ramesh Cc: davinci-linux-open-source@linux.davincidsp.com Subject: Re: EVM 6467 board doesnot bootup 2008/9/29 Ramesh <[EMAIL PROTECTED]> Hi , After I tried to run one demo code on DM6467, I am not able to boot up the DM6467. ########################################################### DM6467 EVM # printenv bootdelay=3 baudrate=115200 ipaddr=192.168.1.201 setenv=bootcmd nboot 80700000 0 a0000 serverip=10.65.103.160 bootfile=uImage nfshost=10.65.102.67 rootpath=/home/Ramesh/workdir6467/filesys bootargs=console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=10.65Mstdin=serial stdout=serial stderr=serial ethaddr=00:0e:99:02:b3:47 bootcmd=bootm DM6467 EVM # boot ## Booting image at 80700000 ...
