Well, I recommend you start reading the documentation now.
There is a section "7. Mounting Target Components via NFS" which
explains that you have to run the ELDK_MAKEDEV and ELDK_FIXOWNER
scripts.
I bet a case of beer that you didn't do that yet.
What is the reasonable amount of flash to have for a minimally configured
Embedded Linux system?
Depends on what you want to squeeze in. I have seen systems with just
128 kB. Obviously this is just enough for the bootloader to boot the
kernel over network. There are products on the market like Bluetooth
LAN Access Points or ISDN routers which have just 2 MB flash. With 4
MB flash you can set up a powerful system including things like
network access, web server, and Microwindows or Qt embedded based
GUIs.
I have not seen a system with less than 4 MB flash lately.
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.
If thisi s all you need (just one binary) you can plan for some 600kB
for the compressed kernel image plus some 800kB for the application
image. 2 MB flash will do for such a setup - but please note that
software tendsa to fill available space, and I bet you will have
ideas for things to add once the box is running.
All we need from the OS is network support. Probably using Linux is an
overkill but since it's free. :)
Happy hacking.

Thank you Wolfgang,
That was it. I forgot to run those script.
After running the script, the console works and I can telnet without any
problem.
Now I can start hacking and get it customized for our custom target.
Thank you all for helping me get it up and running.

Hello again,
I need more help!
Some time, when u-Boot is trying to download the linux kernel image over
tftp connection,
I get the following error. Any one have any idea what may be causing it?
Also, I was wondering if it's possible to make u-boot image that will work
with 256KB of ram/flash.
I tried changing TEXT_BASE to 0xFFFC0000 but I get an error during boot.
Something about the reserved memory is less than required. Is this possible?
Thank you.
Brian
