Check that your installation of the Sandpoint LSP actually completed
without any errors - I found that the HHL-2.0 release had some problems
and many of the target binaries were not installed properly (the first
time through the install process it hung up, and although it appeared to
work the second time it didn't install all the packages that it should).
You can check this by doing an ls as follows, which from a (fully
installed) development host should look like this:

host$ ls /opt/hardhat/devkit/ppc/82xx/target/sbin
MAKEDEV*    ifdown*                 lsmod@       rmmod@

If many of those files are missing from your installation then you have
the same problem, which explains why your target can't find /sbin/init.  I
modified the HardHat installation script and did some parts of the
installation manually, but I don't have my modified version any more.  I
don't know if MontaVista have developed a fix for this yet, but I did tell
them about it several months ago.

Can't run init... MPC8240

[윤동석]

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
