Re: Upgrading Firmware on Thompson DCM475

said by Teddy Boom:

Not very thoroughly tested yet, because the upgraded modem is not subscribed on an account, but it certainly did the basics.

Once I've reprogrammed my own modem a few times (also not subscribed), I will likely borrow a subscribed stac 02.08 modem from a different buddy, and try it on that one. That should be the acid test, I think.

To be honest, if it boots it is good. I'm just a little paranoid

Up-to-date, at last!
Same deal. I replaced image0 at first, but the modem came up as 02.08 still. Then I flashed the exact same firmware into image1, and.. presto!

Also verified that the MAC address is still the original, and it is.

The final version of the flash rig. Pretty darned simple.

I plan to only do local modems in the Ottawa area for now.
Perhaps you might contact user Teddy Boom (send him a PM from this site) and inquire there?

I plugged my upgraded modem into the cable line just a few minutes ago, and it sync'd up with 4 downstream 1 upstream channels just fine. Of course it is still an unprovisioned modem, so it got an internal 10.69.x.x IP address rather than a "real" internet address. But still nice to see it actually works.

Okay, I've just now upgraded a second modem. This time, we tried the second image location first, and it worked. So no need to overwrite both images, just the second one.

And I am connecting with no problems so the flash was good.

Now to see if it has resolved the periodic disconnect problem.

I am interested but I am not having any major issues with the modem atm.

Mlord, I'm in Ottawa, in Orleans. How long does the flash take if I'm able to drop it off to you?
Thanks for all your work on this one!

It takes about 20 minutes but you may want to plan to be there for a half hour, just in case.

Lothario & Shoeman1975,

Allow about 30 minutes, start to finish, for updating the modem.
If you (or others) want this done, then PM me (click on mlord at left, and send me a Private Message aka. "PM").

Cheers

Been running the updated firmware for a week now with no problems. It also appears to have resolved my periodic disconnect/reconnect problem which was my impetus for getting the upgrade done in the first place.

Thanks again for the help mlord.

Do you have channel bonding yet? My modem has been relatively ok but am still getting it upgraded.

I've now got a simplified flashing rig on the breadboard.
Simpler? How?

Well, this one doesn't require a PC at all. I've coupled a raw Atmel ATMega328 chip (aka. "arduino") with an SD Card socket. Put a firmware.img file onto an SD Card and the "arduino" reads it and flashes the modem with it.

No PC, no slow serial connection. So the flashing now takes under three minutes for a 2MB image. Still glacial compared with the theoretical speeds, but 2X the speed of the earlier setup!

I'll probably solder up a board with this one on it, to free up the breadboard for other uses. Some pix coming later.

The latest SD-Card based flashing rig.
said by mlord:

This is the latest incarnation of the flashing rig.
Standalone (no Linux PC required), turnkey.
Requires a DC power source (4V - 16V), and not much else.

The firmware.bin file is read from the SD-Card and written automatically to both flash partitions, if not already in each.

Is there anyone doing this near markham, Ontario?

Thanks I got a message into him. I wish there was a simpler at home method to force the update, but oh well.

Well, I could try accepting a "gear deposit" and then mailing the flashing kit (pictured above) to folks, then refunding the deposit (less outbound postage and a $5 wear'n tear fee) when it gets returned.

But probably not economical that way. Postage alone would likely be $8+hst each way.

It would work with a trusted group of technically capable people that didn't mess up your stuff. I would get the gear, pay the deposit and then ship direct to the next user rather than going back and forth (saving the expense).

I don't mind paying a little extra for the convenience.

FYI I am an at home dabbler in electronics having flashed consoles, sat receivers etc over the last 15 years.

Let me know if it makes sense, otherwise I am going to have to make a special trip downtown.

If there are others in Markham, Richmond Hill it may make more sense to pass it around so that mlord makes his money back faster.

Something I could do, would be to make a duplicate of the flash rig, and sell it outright to one of you North Toronto area people. You could then provide the service to others in your area, and quite quickly make back the cost of the rig by charging a modest $5/flash fee.

The rig cost would be around $50, I think.. gotta add it all up.
But there would be a bit of a delay while I source another SD card slot.

Cheers
