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. |

Up-to-date, at last! |
Also verified that the MAC address is still the original, and it is.

Perhaps you might contact user Teddy Boom (send him a PM from this site) and inquire there?

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. |

said by mlord: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.

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. |

said by mlord:The final version of the flash rig. Pretty darned simple. 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.
