Hi, Your u-boot parameters are truly broken. 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 $(videostd) variable to be picked up at boot time - the 'run setboot' was the trick that caused bootargs to be reset with the expanded variables. So, you should now understand that your lines.... setenv nfshost 10.65.103.160 <http://10.65.103.160/> setenv rootpath /home/Ramesh/workdir6467/filesys setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=$(nfshost):$(rootpath), nolock mem=120M ...will not work.
