I've scoped the serial interface and all signals are correct. The bit size shows both directions are going at 9600. Handshaking is correct. Easy Rider reports, like it should.

But GDB just plain don't work on this thing.

Is there anyone who would be so kind as to flash this chip for me because I can't get into the thing no matter what I do.

Or if someone knows what 'secret' there is to making that silly program *work*.

Only "secret" I know is making sure that
jumper JP1 is cut.

See section on the webpage about the serial port for location
on the board if you can't find it.

Assuming you've done that and it still doesn't work,
email me at the address on the webpage (bigbrd@...)
and I'll send you my address and you can mail you
flash to me and I'll program it for you.

Yeah, I cut the jumper first thing. I don't know, maybe there's something wrong with the existing flash code itself because it won't connect to an ISP either.

I sure appreciate the programming offer because I don't think there's any other way to do it with this one.

Super thanks. I got the flash, reloaded Dave's pre-made image onto the drive, and she boots.

Two questions. It complains it can't find a signature on the swap file. What do I do for that?

Second, how do you logon? I mean, what's the root password? Everything I try says no good.

Never mind on the password. I had misread the text file.

I fixed swap too.

Just be carful with that disk image that you got from me. There may be some things that are specific to my network and may need changing.

Thanks for the tip.

Yes, I've noticed that, although it seems they're things I would have expected to change anyway, but I can't say for sure because I haven't found a magic NIC yet.

At the moment I'm just playing with the distribution itself and had downloaded the potato dist from you as well so I could put it on the webpal drive but Apt can't find things with all the files in one directory because it expects the debain tree, so I'm re-downloading arm potato from one of the archive mirrors along with security updates. I'll then them put it on my webpal drive with that structure so I can install from there.

Back to justdavesj if you're reading, I hope...
I finally found a KNE20T on ebay and have it almost right but how in the world do you get DHCP to work? apt-get insists on DHCP-CLIENT, even if one tries DHCPD, but the network won't start complaining "make sure config_packet and config_filter are defined in your kernel configuration."

PUMP, manually started, will get a lease assignment but I can't figure out how to get PUMP to run instead of the dern DHCP-CLIENT.

How did you get DHCP on your network?

Also, were you able to get Mozilla to install? After 14 hours of waiting for it to finish "registering chrome" I'm not very optimistic.

Then you can't remove it because it hangs at the same place and forevermore apt-get complains it can't finish configuring anything network related.

At least I can get the network up manually.

As I recall, you have to change the kernel boot parameters to specify dhcp. I looked over my running webpal and don't see anything in the rc files that does this function.

Thanks.

I'm not sure what change the kernel boot parameters means. And does that require a recompile or simply a config file somewhere? What boot parameters are these?

Anyway, I did manage to get pump working. Near as I can tell the DHCP-CLIENT, since it was broken, must have been also breaking pump as both were in rcS.d and once I got all vestiges of it removed DHCP lease assignments worked, via the remaining pump.

I'm thinking that pump must have already been there because I don't recall installing it and didn't know the 'name' (I automatically look to for resembling 'dhcp') till trying to find the problem. Unless it just happened to come in with something else I installed.

For those like me, who are not intimate Linux gurus, to use dhcp, whether by pump or another client, you need to set eth0 to use DHCP in the interfaces file located /etc/network. E.g

iface eth0 inet dhcp

(plus setting hostname, hosts.deny, hosts.allow, and the rest, as one can find in a typical Linux HOWTO) Pump shows up in /etc/rcS.d/S40pump

Funny enough, if I set it up as a web server I'll have to change it to a static assignment anyway for the DSL NAT port forwarding, or DMZ.

Ipchains says incompatble with the kernel too, btw.

Browsing from Windows into the box works but I can't mount any windows shares because smbfs isn't in the kernel either, or so it says, and I would *really* like to know how to get that added.

The dhcp enable is in the kernel parameter command line that you flash into the webpal. You would put something like the following in the params partition:

command=root=/dev/nfs nfsroot=SERVER_IP:NFS_ROOT ip=dhcp video=acorn:dram:384k

I'm fairly certain that my kernel has smbfs compiled in. You can get it from my ftp site:

ftp://justdave.us/webpal/

I believe it's the one that says ide boot although the zImage file has a more recent date. You could try both.

Thanks, and sorry for the confusion. I had intended to use your kernel (did use the HD image) but I couldn't get any flash method to work and bigbrd gratiously helped me out of the jam. So it's whichever kernel he flashed into it.

I'm rather reluctant to try flashing since I have no recovery mechanism if I foul it somehow and pump is working anyway and I can get around samba with FTP, at least for what I'm doing at the moment.

Do you have any suggestions on what would be the best partition arrangment with one 2 gig notebook drive for swap and system? Mine seems slow and I'm wondering if swap isn't in the best place.

My webpal has a 1gb swap partition set up. I'm not sure that there is anything to make it 'faster.' Adding more memory is always helpful.

Holy Moley... a GIG for swap? Is that being used? Or does a huge one make access quicker for some reason? I mean, TOP reports I'm using like 2 to 5 meg (of a 128 meg swap), depending.

What I meant about speed was number and location of partitions, like to minimize seek delays, etc., but I'm afraid there's not anything I can do about RAM as I have 32 Meg and I doubt my eyes/steadiness of hand are up to soldering anything with that tight a spacing to enable a 64 Meg stick.

Since I finally figured out how the permissions on ftpd work I might just remove samba entirely because it consumes a lot of resouces, comparatively speaking. And I've already moved from Apache to cern-httpd for the same reason. I know cern is old but it's not like I'm setting up a web store or anything complex.

It's becoming quite a learning experience to manually configure Debian and I appreciate the help.
