Re: Upgrading Firmware on Thompson DCM475

Its really good that these forum members have figured this out.

Its really bad that a firmware update can't be sent thru the system to upgrade existing products

Thanks Mlord,
Everything working fine so far. I think Teksavvy owes you a free month of service for what you are doing for some of their customers.

A gesture from TSI would be nice, but they definitely cannot afford my usual hourly rates. My wish is that the pain endured figuring out this fix can help keep others going on TSI Cable. That's why I do the upgrades almost for free.

As much as I'm among the first to criticize their lack of great customer support these days, there's really no good alternative to TSI.

Cheers

I really like these EZ-Hook XKM grabbers. They latch onto SMD pins quite solidly and without shorting on neighbouring pins or clips.

Expensive, though. And very difficult to solder wires onto. Not an issue for the Logic Analyzer, which has the proper mating connectors, but for this rig.. somewhat fragile.

I've got a shipment of very similar looking clips on the way from China, with proper solder tabs. I plan to switch this rig over to those once they arrive, assuming they can latch onto things as well as the XKM grabbers do.

EDIT: there is a variant on the genuine XKM hooks that might work better: XK25SS hooks are designed for easier attachment of patch cables, and look like they could be soldered onto as well.

Cheers

Very annoying.. I guess it is Dremel time

I might have to break out the individual test clips actually. It is only a few connections, and those big all-pin test clips aren't that easy to attach, so I might be better off with your setup anyway..

Mmm.. The last two modems I've upgraded here now both had the processor heatsink rather close to the flash chip -- too close for the full IC test clip that Teddy Boom uses.

The latest one actually overhung the flash, preventing easy access to the pins. I managed to slide my grabbers under the heatsink onto two of the pins, but the third pin on that side was not accessible. Fortunately, this was the +3V power pin, so I used the closest pin of the nearby white header instead. Worked fine.

Rogers has the capability and should have no problems to send firmware updates to modems that are accepted to use on its network.

They did it before, I don't get why they wont do it again.

Basically it's not really mentioned but, if a company stop or refuses to give customers a service for something, it really shows how much Rogers dislikes Teksavvy (unofficially of course). Heck for some reason I get vibes that they brainwash all their employees to hate competition.

Because the way I theorize this is:
If Rogers didn't have competition, more people would have to 'resort', that's the keyword, resort, to their plans and cough up a larger amount of dough. Now with Teksavvy and third party internet, they feel that they are 'losing potential profits' now that they can sell usage to Teksavvy, etc. but not keeping the customers so they can't milk them. They think that causing distress (but they obviously won't admit to that) is a way to make people leave third party back into their milking game.

The thing about Canada, is that almost every large position of power, be it corporate or government, is into 'milking' or abusing something to it's non-existent. Today, you are starting to see the cracks of the social system, with unions and such at war with government on 'wanting to be spoiled with more money', and government wanting to pay off the debt but can't seem to 'stop spending money'...

Just recently I read that the construction industry was corrupted by a Canadian line of Mafias and was only figured out and publicly testified this week.

Slowly, but surely, all things 'power' is heading to the direction of corruption.

----

As for this thread, I have a DCM 475 also but I don't see any changes on it, other than weird packet loss and lag spikes that occurs randomly every other day...

I totally check all my network and none of them are causing the huge 600ms latency spike across outside from my home. Could be the 'peak' hour thing, but I find that strange because it's not like Teksavvy's own nodes are hitting max capacity that easily right?

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

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.

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

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

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!

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!

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.

Cheers

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

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

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

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.

How much would you charge me to do this for me if i ship you the modem?

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?

Trust me...we are working on this. On many different levels. Including looking at hacks like in this thread.

Gotta call bull sh!t on this. Three months and the best you can do is say we are working on it in a message board thread. Teksavvy just lost me as a supporter.

Will Teksavvy be giving me a credit for the cost of flashing the modem they sold me? Had a perfectly good Motorola that you said was too old to use. More BS.

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

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

Which of the two flash images did you replace, the first one, or the second?

I ripped 02.16 from another modem this afternoon, and found it in the first partition. The second partition had 02.08. So perhaps the "factory" image is the one at 00200000 rather than the one at 00010000.

Cheers

I found the same thing. On the 2.16 modem it was 2.16 in image0 and 2.08 in image1. On the 2.08 modem it had 2.08 in both locations. I replaced both on the 2.08 modem. I had to erase and flash the entire firmware at the time, because I didn't have a proper USBJTAG xml file for the DCM475. I've now created that xml, so I could experiment, but I don't have any modems to play with any more

I don't know if my theory about the two images works. It seems to mostly work, and on the DCM425 it seems to always work that way, but... I guess there must be an environment variable that chooses which fw to boot from. Annoying.

Or more likely, it doesn't matter.. bootloader just picks the newest valid image (?).
