agreed. So I take that to be read as: go update the mtd code
manually, overwriting the old drivers/mtd and include/mtd directories

if so, what version of mtd should I use.. I understand that currently
the mtd guys are not supporting ancient kernels (2.4.20)

btw: I already know I should update my kernel... I've already been there
w/ my client, they can't upset the apple cart yet.

anyway I've already resolved this by not printing out the destination of
the link....

Ah, sorry I see what you are getting at.. I use U-Boot to write the 
jffs2 image
that I create on my PC host. I tftp the image, and then use cp.b to the 
address
that is my flash address space.

I use cp.b since it does not work doing simply cp.. because of the word 
length...

I have also verified (in u-boot) that the data that was copied into 
flash
with no errors. (cmp.b command).

so here is the exact output from my terminal :

CENTILLIUM-IAD # run progjffs

sorry this took so long to get back to you on.. I was not in my office 
earlier this week and I *really am* trying
to give you exactly what you are asking for :]  thanks again for your 
patience and help!

Mike
