Brian,

I ran MAKEDEV in the util directory (it creates a lot of nodes).

insmod nftl.o

Now you should be able to mount /dev/nftla1 provided it has a filesystem
on it.

You can run fdisk on /dev/nftla to create partitions, etc.

Look at /dev/mtd0 (I captured it with dd) and you can see the start of
the firmware bios extension (0x55aa).

I also had trouble building the utils.  It goes wrong with

../include/linux/mtd/mtd.h:6: parse error

My kernel sources are in /usr/src/linux and I think this is where the
Makefile expects them.

Same here.  Now I'm doing what some others on this list have suggested
and using syslinux to boot the kernel with an initial ramdisk.

Beginner with DoC

[Brian K. Michalk]

My system:
Advantech biscuit PC
DoC2000, 72 megabyte
Linux (slackware) 2.2.6

Eventually I want to be able to boot off of the DoC, but for now, 
I'll settle for making the kernel modules work.  I read the 
documentation I could find, but still had problems.  Here's
what I did:

Downloaded mtd-19991025.tar.gz, extracted, compiled.
	I get a compile error for the various utilities.
Download mtd-19991025.diff, patch and compile -- no help,
	so I comment out the offending utilities.
insmod mtd -- cool
insmod doc2000 -- cool
Okay, now I want to see if I can see them with fdisk, but I've
	got only a few clues as to the nodes.  I tried
	mknod fla b 62 0 through fla4 for major IDs 62, 90, 31, 93,
	and 44.  Fdisk never finds any of the devices.

So, what nodes am I supposed to make?

Thanks for the help.

I'm using the patched LILO to boot off the flash, and works like a 
charm (there is a limit to the size of the kernel, though).  It was a 
bit difficult to patch lilo version 21, and create all the necessary 
files, but it now works.

Not everybody can afford DOS for each of their units, and freedos 
isn't exactly ideal, at least with the bit I played with it.

I'm attaching my patched lilo-21, my patch file, and the boot.b file.
Feel free to use it.

Ahhh.  I was just about to send you my log, then I thought, hmmm, 
I ought to try fdisk /dev/nftla1.  Bingo.  It works.

Interesting thing is that fdisk shows four partitions already on the
chip.  I'll delete them and see what sort of damage I can do now
Thanks for the help.

Re: Beginner with DoC

[Brian Michalk]

Spoken like a person whose been bitten.

I did not get the kernel drivers to compile properly, but gave up as soon as
I found out that the patch was for the kernel drivers.
My application is pretty interesting ... at least for me.  It's for data
collection in a vehicle, and the computer is essentially a remote embedded
PC.  For years I wanted something like this with a UNIX I could afford.  Now
with DOC, I can have my computer, log in to it and do anything I would have
been able to do with a full blown computer out there.

I've always fiddled with the various stamps, flashlight controllers, and
lots of ZWorld controllers, but this is going to be much better.

PS: To whom it may concern:
May I make a suggestion (as a newcomer)?  This list has the "reply to" set
to the original author.  I'll bet there are a lot of private email
conversations going on that could answer a lot of the problems for people
like me.  It would be nice if the replyto were set to the list as well as
the original author.

When fdisk is concerned, if something appears odd, I don't mess
with it before I understand what has happened.  I once had to play
around with the names of the devices since I had a program that
would not install itself to anything but partitions that are named
/dev/hda-hdd.  So I renamed /dev/fla to /dev/hda, and installed it.
However, when I ran fdisk, I got confused with all the names, and
instead of destroying the flash, I destroyed my hard disk!  Luckily,
most was recovered.

If you manage to install MTD drivers in the kernel, and not as
modules, let me know.  For some reason it doesn't work for me.
