Topic: Comtrend CT-6373

The content of this topic has been archived between 8 Feb 2018 and 16 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello,
I have seen that some Models of Comtrend are supported.
My Comtrend DSL-Router CT-6373 is not on the list.
Is there are chance to support this device?

Probably it can be supported. I think this board uses a bcm6358 SoC which is already supported with other boards.

Some information is needed to achieve support:
- CFE board ID,
- are you able access to the CFE web interface?
- do you have access to the router via serial port?
- memory flash-chip model

Do you have any flasheable firmware from the manufacturer to watch the header? I should be necessary to produce an Openwrt firmware which CFE can accept it.

Also it would be nice some quality pics of the board to start adding info to the wiki.

Hello,
in the evening I will bring you the rest of your wanted information.
Here the Versions of my Router

Board ID: CT6373-1
Software Version: I111-S306CTL-C01_R04
Bootloader (CFE) Version: 1.0.37-6.8
VDSL Software Version: 09.03.02, 2006-12-24
Wireless Driver Version: 3.131.35.4.cpe2.0
ADSL Version: A2pB021g.d19d

Onboard Chips:
BCM4318KFBG
ST M29W640FB
MIRA P3S56D40ETP

Some Specs

I can access the Webinterface. Is the CFE Interface diffrent then the managment WebIF?

Ok from the firmware you posted whe have this (for future image builds):

reserved2 (240-255) Unused at present

Only blue values are important. It seems easy at least to generate a compatible image. But it will be more important to know  better the hardware, and of course a bootlog would help.

Hy.
Here pictures from the hardware.

Hardware Pictures

Do you know how the get a bootlog?
I can not find any serial pins :-(

I've built a firmare for your router

http://files.myopera.com/danitool/linux … fe.bin.zip

Could you test it?

Try to flash it with CFE doing something like this:

Get the firmware openwrt-CT6373-squashfs-cfe.bin
- Unplug the power cord
- Press the reset button, don't release it yet!
- Plug the power cord
- Wait >15 seconds
- Release the reset button
- Browse to http://192.168.1.1
- Upload .bin file to router
- Upgrade the image
- Wait for it to reboot
- Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1

Also I suspect this is the serial port
http://files.myopera.com/danitool/xx/comtrend-6373_serial.jpg
Could you confirm it?

Hello,
You are right. This is the Serial Connection.
I connected my DKU-5 Cable and get a bootlog
Here the Bootlog

Bootlog.txt
dmesg

Edit:
I testet your Firmware and it works great. No problem so far.
I attached a dmesg too

Now, where the device is working, I have a question.
Where can I configure the adsl settings or which packet do I have to install for adsl?

Sadly, Broadcom didn't release any source code for the adsl part.

WIKI wrote:

The support for Broadcom 63xx is at this state :

Full Linux support for BCM6338, BCM6345, BCM6348 and BCM6358 with runtime detection of the SoC on which the kernel is running
GPL drivers for Ethernet, OHCI, EHCI, SPI, Watchdog
No available drivers (neither binary, nor GPL) for DSL, ATM, VoIP, on-board SLIC/SLAC

Spite there is some work on the adsl drivers
http://bcm63xx.sipsolutions.net/
there aren't anything still usable.

Could you locate the gpio's of leds?
Use gpioctl:

gpioctl set X
gpioctl clear X

X is a number = 0 to 40

Also you can try to locate the gpio for the reset button:

press the button
gpioctl get X
release the button
gpioctl get X

if the state of the gpio changes, that gpio is the reset button.

Also would be interesting to make a backup of your bootloder. It might help to hack others bcm6358 routers.

dd if=/dev/mtd0 of=/tmp/CFE_ct6373_backup.rom

Here the bootloader
gpio I will check this evening.
but how shall I check the reset button.
when i press it the device is not reachable anymore, correct?

So, after testing with gpioctl i'm a little confused.
Because gpio 6 was Low, I set it to high.
At the first time power + adsl led went up.
After a clear and set again gpio 6, the Line Led went up. And so on.
Only USB and Power are working normal.
Here my testing.

0 = power
3 = USB
6 = *
9 = Wifi
35 = Button

*:
1x6 = power + adsl
2x6 = Line
3x6 = FXS1
4x6 = FXS2

I'm not sure if some gpios are controlled with a 74HC64 IC in your router, do you have this chip at the board?

Since I've never had this behavior, my knowledge is the same as yours about the gpio 6 weird function.

you are right. there is a chip with this name onboard.

http://www.abload.de/thumb/p1030859kopietgvhy.jpg

what does this mean and my major problem, what about adsl?
actualy its only a hotspot devices :-)

This means the board structure for controlling those leds is more complex, something like this
http://pastebin.com/Qna3bSgZ
But I have no idea how make the same with the 74HC64 in your board structure.

About the adsl drivers we can say: there is nothing.
But still you can use it as a regular router without adls configuring (with VLANs) one switch port as WAN.

Thanks for your support.
For the Future, which Firmware can i use for this Router?
Or shall I use the Image Builder?

Hy,
one more thing.
this router has two pots connectors.
Can I use them with pbx software?

I've made some patches for this router:
http://files.myopera.com/danitool/linux … .patch.zip

- Apply this patches before building: CT-6373-1_network.diff , image.diff
- And drop the patch CT-6373-1.patch into the trunk/target/linux/brcm63xx/patches-3.0/ directory

About the port connectors, do you mean the FXS ports? Probably you can't use it, as far as I know there aren't drivers, but I'm not totally sure of this.

(Last edited by danitool on 16 Feb 2012, 14:49)

sorry, I have never build a image bevore.
where shall I apply this diff files and where can i get a trunk image builder?

Install the needed applications for building like svn and other stuff and get the build tree:

svn co svn://svn.openwrt.org/openwrt/trunk/

then apply the patches

patch -p0 -i CT-6373-1_network.diff
patch -p0 -i image.diff

drop CT-6373-1.patch into the trunk/target/linux/brcm63xx/patches-3.0/ directory
then

make menuconfig

select your target, and the stuff you want for your firmware
and make the world:

make V=99

(Last edited by danitool on 16 Feb 2012, 15:51)

i compiled it and uploaded the new firmware but the router was not reachable anymore.
perhaps i forgot some checkboxes in the "make menuconfig"
now i installed your firmware again :-(

If you have a serial port, you can locate where is the problem. You can post here the bootlog, it might be a negligible error.

No errors reported, I can't locate any problem. Did the the router hang at this point?

Also you can check if you have the file

trunk/target/linux/brcm63xx/base-files/etc/defconfig/CT6373-1/network

I don't know if the board structure I've defined for your router is causing some trouble. You can check it at

trunk/build_dir/linux-brcm63xx/linux-3.0.18/arch/mips/bcm63xx/boards/board_bcm963xx.c

at the line 2039 is defined your board, you can edit, delete the defined button for example, then save, delete the associated binary board_bcm963xx.o file and make V=99 again

now I flashed one more time my self compiled image and unchecked "keep settings" in Luci.
Now its working. 
Is this normal?
With your Firmware I could set wifi power to 20db.
With mine the max is 18db. Have you used an other wifi driver?
