getting Linux working on IBM Walnut demo board

[Brian S. Park]

Thank you all for good suggestions.

It turned out that ELDK default setup does not have any dev files. How do I
create all the dev files I need?

 >[root at karla2 dev]# ls
 >initctl  log  null

Also, I have a general question about Embedded Linux.
What is the reasonable amount of flash to have for a minimally configured
Embedded Linux system?

My target will be running small (<<1MB) program which will take commands
over TCP/IP network.
So, I want to know how much flash memory we should put on our custom target.
We do not need support for PCI/Video/Sound/HD/SCSI/Parallel port/...
All we need from the OS is network support. Probably using Linux is an
overkill but since it's free. :)

Thank you for any input.

Is this normal? Do I now need to configure the target file system to enable
telnet?
