From using both the ECI and huawei hg612, I have noticed that I get more jitter using the hg612. The eci seems to perform a little better on my connection. may be different for your connection.

Josh -- A quick couple of questions for you. When you had your FTTC service installed, which VDSL2 modem was officially provided as the active CPE? The Huawei or the ECI? As you probably realise, Openreach supply the modem to match the DSLAM in the FTTC.

If your installation was a Huawei, I wonder from where did you obtain the ECI B-FOCuS modem? Care to share the information, please?  ;)

I was supplied with the ECI, and purchased the Huawei off the bay. I know ECI modems are hard to track down, I have not seen one on eBay!

Thank you for the update.

I can see that without some degree of co-ordination, when one does turn up on eBay, we will most likely be bidding against each other. :doh:

Excellent work!  I have the ECI model B-FOCuS V-2FUb/I Rev.B) and after replacing the HH3 for something running OpenWrt (finally, real routing!) last night, I'm now shifting focus to the other mysterious black-box (the modem).

GPL advocate, not too bad with Linux, near zero embedding skills though.  Always keen to get my hands dirt though, albeit usually [learning] on the job!

uklad/asbokid any thing I can do to help?

I'll add, there were a couple of broken links on this thread.  Does anything need hosting, as I can do that.

Hi nimda!

Great news that you are joining us!  You sound very qualified for this important voluntary position!

There are several possibilities for unlocking the ECI.   The first task must be to gain shell access through the serial port, following uklad's pioneering work.   A USB-TTL bridge is an easy and cheap way to do this. The controller costs less than £2. [1] [2]

It would be rewarding to crack the LZMA mechanism used to lock the embedded file system, since the same mechanism is used by many other manufacturers, but that's probably not an easy hack. Though it certainly offers the most kudos if successful!

The priority must be to re-enable web and telnet/ssh access from the LAN-side. This should be possible through the serial shell access, after the system has booted. Once an unlocking method has been discovered, then a more permanent solution will involve modifying the flash file system.   uklad has generously offered his ECI for target practice for this, but the likelihood of bricking it is quite high, so it's probably wiser to find an unwanted one!

Your hosting offer is much appreciated :-)  SFAICS, the dead links are uklad's original NOR flash dump from the ECI which he uploaded to mediafire, who seem to have deleted it, for lack of downloads(?), and the PDF of Sweetman's book on MIPS Linux (Morgan.Kaufmann.See.MIPS.Run.2nd.Edition.pdf) ?

Uklad's original NOR flash dump (ecinand8mb.bin) is duplicated here [3]

Welcome aboard!

cheers, a

Thanks, glad to be here.  I'm looking forward to learning along the way too!

I purchased the PL2303HX USB to TTL Converter Module, it'll take a while to arrive though "Estimated delivery: 12-24 working days" but it was free delivery from Hong Kong so can't complain!  I'll start work on the serial link once the order arrives.

I'll leave this one for now, I don't feel ready for tackling algorithms just yet.

I don't mind testing serial connections, but unless I had a spare, I'd not yet be prepared to put my modem on the line.  So, thanks to uklad for the donation, generous indeed.

No problem at all, I can accommodate ANY hosting needs, especially to aid the greater good of a freed community --decentralising, and taking back control/data, is my computing MO.

In the meantime, I'll take a read of See MIPS Run.  Also, would you mind sending me (or attaching) the bin file, as I don't want a Google account --yes, one of those!

Once this is opened, what then?  What are the options?  Fundamental question, and possibly obvious answers, but I'm naive in this area of computing, what cool things can be done?

Am I right to assume this will require reinstating header-pins?  Is this JTAGing?  I've never (knowingly) played with this before.

Lastly, did uklad not get shell access:-

Also I did not mention I could login to the unit on the UART console, username and pass where admin admin :0)

Is it not straight forward to "re-enable web and telnet/ssh access from the LAN-side." ?

Hi again, nimda,

No problem at all, I can accommodate ANY hosting needs, especially to aid the greater good of a freed community --decentralising, and taking back control/data, is my computing MO.
A man after my own heart!

Hi.. the perms were stuck. The dump is downloadable now without a gmail account..

Good question.. I think people just like getting under the bonnet.  Paul (Bald_Eagle) and Burakkucat have done some amazing things with graphing scripts, using the low-level diagnostic xdsl data that the unlocked Huawei provides.

My current interest is to try and 'fit' that diagnostic data, especially the channel characteristics (aka insertion loss aka attenuation) to parametised cable reference models.   This would hopefully lead to an accurate analysis of loop quality, and estimated loop length.  The data could be analysed for common fault conditions - bridge taps, etc.

Other options include the development of server-side scripts for graphing. This code would run on the embedded device itself.

I guess ultimately, people would like to see an open source router distribution (openwrt et al) running on these devices, but that would involve the release of the DSP drivers by Broadcom and Lantiq, who are less than forthcoming.

cheers, a

EDIT:  Yes, obtaining serial port access involves soldering the header pins back onto the modem board.  It's not hard with a fine-tipped soldering bit.

JTAG is a different serial protocol, primarily for debugging hardware. It's similar to SPI and has a clock signal (TCK), two data lines for input and output (TDI and TDO) and a control line (TMS) to manage the state of the JTAG engine. 

Unless the bootloader gets wrecked, it should be possible to unlock the ECI using just the TTL serial port.

For a short time only (just to allow you to download it), I have made the file available from a temporary location. Please let me know once you have got a copy.  ;)

[Edited to mention that the link to the above temporary location is now deprecated.]

Yes, uklad indeed got shell access.

It should be. Unfortunately before uklad got there, he was distracted by his family who obviously have no appreciation of the importance to this work!

Thanks burakkucat  :)

I'm always willing to assist, where I can.  ;D
