Dear

I am working MPC8240 custom board with Sandpoint8240 BSP
from MVista CDK 2.0 .   I think that I made something wrong.
I tried to make run "init" ( init is located /bin/init,  sbin is symbolic link to bin),
but didn't run it so I printed error code  with printk function.  Error code is 2
Error code 2 says that file does not exist. I can't find debugging point.
Small advice gonna be big hands to me.


Following is What I did and partial souece and console output using printk

[ Work Sequence ]

1. Made ramdisk.image.gz and copy it to "/opt/hardhat/devkit/lsp/motorola-sandpoint/linux-
   2.4.2_hhl20/arch/ppc/boot/images"
2. compiled with command " make zImage.initrd"
3. Change to directory   "/opt/hardhat/devkit/lsp/motorola-sandpoint/linux- 2.4.2_hhl20/arch/ppc/boot/images"
4. Make it to srec format
    zsrec -s 900000 zImage.initrd.sandpoint  > image.hex
5. At vision prob I converted it to bdx file
    I got image.bdx
6. I downloaded "image.bdx" using vision prob
7. go 900000

        if (execute_command)
                execve(execute_command,argv_init,envp_init);

}
