Re: Upgrading Firmware on Thompson DCM475


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

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

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?

You'd have to come into downtown Toronto and find Teddy Boom See Profile

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.

Just a plug for mlord and his service.

Upgraded me to 2.16 last weekend and its been a solid week, no disconnects.

Well worth the $5 and my time!

I'm in Thornhill; if you do decide to do this, I'd be happy to share in some of the cost.

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

if I plug the modem in the home of a rogers customer for a day would the firmware get automatically upgraded ?

Nope, because the modem will still connect to your Teksavvy account regardless of where you plug it in.

Updated flashing rig.
Updated version of the flash rig, with a more minimal SD card slot.

Haha I used to love doing this stuff, but that along with many other enjoyable hobbies went out the window when 2 kids and an ISP run your life.

Unfortunately this is correct,they won't do firmware upgrades like this.

Sounds great!

I'd buy it and then resell it locally to the next guy that wants to flash his modem on the understanding that it just keeps getting passed along with postings in this thread.

Let me know when it is ready and I'll send you the cash.

Seriously? If so, I think I might glob it in places with some hot-melt glue to keep things from falling off the breadboard. And then just ship the breadboard unit down that way.

Need some kind of "usage instructions" though -- I really ought to take some photographs of how to hook it up to the modem. I can do that for my own modem, but need to find another one with the heatsink obstruction issue as well for this.

I would use a huge heat shrink tubing over the whole thing. That's how I protect some of my homemade PCB. Future Electronics in Nepean sell Polyolefin ones which are soft. Not sure if they sell wide enough one for your breadboards. The transparent ones are good for inspection.

Hobby stores carry PVC based one for making RC battery packs etc., but they are hard and non-flexible.

As for "logic probe" (a few pages back), you can find "dupont wire" in places that sell electronics parts from China. They have proper 1 pin connectors that goes into the clips and 0.025" square post in connectors.

:) You mean, like, the ones in the third photo above in this very thread?

@teksavvy.com

Yes. Those types of clips. It works fine with the Tek and old HP clips that I have, except the flat hp logic analyzer clips which uses a crappy pin that are formed by folding.

If you haven't gone so far down the development, I would have suggested reprogramming/re-purposing those $4-$6 "USBasp" cables from China to use as USB to SPI dongles. USBasp is open source programmer for AVR chips, so the Chinese copies would have same design. It uses V-USB, a bit-banging software USB stack. The 10 pin connector has power, AtMega8 SPI port and 1 GPIO line which is pretty much what you need to program SPI Flash. »www.fischl.de/usbasp/

Ideally one guy at each POI area, trained and ready to roll.
I'd prolly be interested in doing this too once I'm shown how a time or two.

Hey all,
I discovered this place because like most of you I was having issues with my Thompson DCM475 dropping signal and rebooting every hour or so. I had contacted Teksavvy about the issue and they basically told me to buzz-off because the modem was a few months out of warranty.

Deciding to take matters into my own hands (its not like you can break a crappy modem more than its already broken) I started to Google. I found this thread and I read up on what was going on. I was able to connect with mlord last week and he updated the firmware for me to STAC 02.16. The modem has been rock solid for the last 5 days.

Thanks again for everything mlord. Job well done!

There is a parallel port to SPI FLASH programmer that only require 4 resistors and a power source. I guess you have to magically obtain a copy of the firmware which tends to be the hard part.

rayer.g6.cz/programm/programe.htm look under SPIPGM.ZIP

>SPIPGM.ZIP ver. 2.1 [98 kB] (DOS/Win9x/NT/2k/XP/Vista/7/Linux) is a tool for programming serial SPI FlashROM memories attached to PC via parallel port cable. It can identify device, read, write, verify, erase and unlock flash memory. More info about needed hardware (CZ-only but schematics is self-explaining) here.

TSI, Mark, Martin,

The last update on this issue from you is over 2 month old.

Reading forum threads like this, seeing the kinds of hacks people have to go through, is the reason I don't recommend TSI internet anymore. Even if someone was to get it today and order a modem from you with proper firmware, Rogers can "update" their network again, rendering the modem again useless.

The fact that there is still absolutely no remedy on this is disturbing, to say the least...

I ended up making the trek down to see Teddy Boom and got my DCM475 modem flashed today to 2.16.

My problem was actually that in the computer parameters for the modem, the "Computers Detected by Modem" would go to 0 and the modem would take 10 seconds to refind the computer and go back online. It would happen at least a couple times of day.

Not sure if the flash is going to help, but I will keep the thread posted to see the results over the next few days.
