Bad magic Number

the variable ip should not be set to 'off' when trying to load file system via NFS, please change your bootargs appropriately (see Getting Started Guide)

Thanks for the feeback

my dhcp is not working correctly so I am trying to assign static ip to the evm and the host machine do I still need to set ip=dhcp

no, please see the following short app note on using static IPs: http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=spraaq0

I have changed the ip= dhcp in bootargs command after that when i boots the board

it hangs over here...

and when I was giving  IP=off in boorargs command, board was giving error "RPC: sendmsg returned error 101" for nfs port. how we can set nfs port on the board, as on the host machine i did exactly the same steps mentioned in getting started guide.

Can you post your updated bootargs?  When you reboot, does it still give you a bad magic number error..? 

The Updated Boot args are as follows

DM6467 EVM #
bootdelay=3
baudrate=115200
rootath /root/workdir/filesys
ip=off
nfshost=192.168.1.203

bootfile="uImage"
stdin=serial
stdout=serial
stderr=serial
ethaddr=00:0e:99:02:b4:81
bootcmd=tftpboot;bootm

right now the output of the evm is this

so it  keeps on repeating this. I have also tried the above with  bootcmd=tftp;bootm the results are same

hope this is useful

I am still very concerned about the lines strikethrough above as they should not appear in the environment.

I do not like the lines you strikethoughed above either; you can get rid of u-boot environment variables by using 'setenv [variable name]'; for example typing 'setenv ip' and pressing return at u-bbot prompt should get rid of 'ip=off;  However, I would not worry about these.

The key u-boot variables are bootcmd and bootargs (others such as serverip, ipaddr, and bootfile are also important).  From you log above, it seems like you are stuck when trying to TFTP linux kernel (uImage) from host.  Check the following

1) name specified in 'bootfile' u-boot variable matches the name of the file in your host '/tftpboot' directory

2) check to make sure you can ping your host from u-boot prompt (ensure hw connectivity)

3) ensure firewall on your host is turned off (see Getting Started Guide for instructions)

I tried to ping the host machine from EVM it says 'host is alive'

while on the host when I tried to ping the EVM it says 'Destination Host Unreachable'.

I have the Redhat Enterprise Linux 4 Advance Server installed on the host can that be causing some conflict [^o)].

I do not believe this is an issue; I seem to recall not being able to ping EVM from host either probrably because minimal software support is available at u-boot time; so long as you can ping your host from the EVM I think you are good to go.

Have you checked that your firewall is disabled on your host and that you have a uImage file under your host's /tftp directory?

Hello Juan

I have been able to solve the issue thanks a lot for your help. [:Y]

I followed the article in the startup guide "Updating and Restoring the Bootloaders" and did the steps required in A.4.2 and A.4.3 on a hunch that I would be able to restore the uboot to its original settings. Doing so the environment variables restored to original state where I had started this process. I then proceeded with setting the static ip as explained in your app note, made sure the tftp was on, the nfs was working, the firewall was off and that I was able to ping from the board.

The Linux has loaded now.[:D]

Thanks a bunch I had been stumped and had been stuck on the issue for some days now.

Best Regards

Umair

Umair,

This is great news!  I am glad to hear you are booting now.  BTW, I use teraterm scripts to automate u-boot configurations and avoid the likelyhood of getting something wrong; as you can imagine, it is easy to overlook something or make a typing mistake (at least for me :) ) when you have to type so many things manually...If you are interested, there are some sample teraterm scripts here http://wiki.davincidsp.com/index.php/Teraterm_Scripts

Those will a lot of help. I had to type so many things again as there is minimal editing enabled.

I will look into them, thanks again.

Best Regards

Umair
