Take a look at the OpenWrtDocs/Hardware/Netgear/DG834GT:

Board IP address                : 192.168.1.1:ffffff00
Host IP address                 : 192.168.1.100
Gateway IP address              :
Run from flash/host (f/h)       : f
Default host run file name      : vmlinux
Default host flash file name    : bcm963xx_fs_kernel
Boot delay (0-9 seconds)        : 1
Board Id Name                   : 96348GW-10
Psi size in KB                  : 16
Number of MAC Addresses (1-32)  : 2
Base MAC Address                : 00:1b:2f:32:ab:31
Ethernet PHY Type               : Internal
Memory size in MB               : 16

The BCM6348 has two ethernet ports ... so I guess, you have to enter two for the number of macs.
And normally the cfe supports http-firmware upgrade, if the addresses are set correct.

So enter your settings, stop the auto run and try to upload the original netgear firmware.
http://<router-address>

Hope that helps

What's exactly the state of this port? can I build the firmware and upload to my router using the web interface (Comtrend 536+)?

Keep the good work!

Yes you can build it up yourself and install it, although you must have a serial cable for the flash and some knowledge of what you are doing. DSL modem as far as I know won't work, but WiFi, switch and USB should do fine.

Follow what T3l3m4k0 said in some posts (although most of those things are already impkemented in the trunk).

Greetings

Thanks sblanco. Is it possible to build an image for upgrading via the Web interface or TFTP? is only a matter of adding some binary info in the header of the firmware? can we do this with an hex editor?

The thing is nobody reported a way to flash the router with the binary file from the webinterface, every single flash was done by CFE as far as I know, using serial cable to access the console. And still after a good flashing, t3l3m4k0 posted a network setting that must be changed in order to get the switch working (I don't know if it was patched in the trunk for making it unnecessary).

If you want to you can try without serial cable, but almost for sure you will need it later for unbricking. I "build" it up myself, bought a cheap DKU-5 cable for Nokia phones and checked where goes each cable and that's it. It is already a USB->Serial cable with level converter for connecting to serial consoles with 3,3 V TTL levels.

Greetings

hi

i complite new kmz for bcm96348, i have netgear dg834GT and i would like to flash, but i dont know how, i try tftp but no work, i search solution on google but i dont find anythink, if somebody can write how to flash this router i be happy

br

@snipers,

like previous post says, usign serial cable

Hi t3l3m4k0,
I inserted more parameters ..
all board number 1,2,3,4,5,6,7 and more mac numbers 1,2,3,4,5,6,7,8,9,10,1,12
but the result is the same(see post http://forum.openwrt.org/viewtopic.php? … 55#p76955).

Can you post me link where download a compatible CFE.bin for DG834GT ?

Thanks
MisteroX

I don't have any cfe for DG834GT , maybe lamaatge can send one copy to you.

If you would, i can send one from Asus (bcm96348gw-11 board) to try, it is working on my Comtrend 536.

Ok, please  send to me your copy from Asus (bcm96348gw-11 board) and I will try with it.

Thanks

Hi guys,
I'm a new comer. I've got a ADSL modem based on BCM6358. The model is RG100A-AA. It's from Shanghai Bell. With 16MB flash and 32MB ram. I've tryed to connect it by a TTL-USB cable. But it does not work. The cable is good. I use it to connect another modem LINKSYS WAG354G V2. So can you guys give some suggestions?
And best wish for thanksgiving.

Hi,
I've been working to build openwrt for a comtrend (96348W-11 board).
I have managed to compile a working copy with ethernet and wifi support following the comments in this post, to get the wireless driver I extracted the firmware as described in http://linuxwireless.org/en/users/Drive … cefirmware. I have copied the resulting folder (b43) in ..../build_dir/linux-brcm63xx/linux-2.6.27.7/firmware/
The I compile as follows:

make kernel_menuconfig
    Device Drivers --> Network Device Support --> Wireless LAN --> Broadcom 43xx
make menuconfig
make V=99

The firmware builds correctly and wireless driver works, but I am still having a problem. I want to use this router as a wireless bridge, to do so i configure br-lan as follows:

root@OpenWrt:/# brctl addif br-lan wlan0
device wlan0 entered promiscuous mode
root@OpenWrt:/# iwconfig wlan0 mode managed key a1a2a3b1b2b3c1c2c3d1d2d3e1 essid

I changed the uci code as explained in a previous post to get lan working. However bridge doesn't work, packets are not being forwarded from lan to wireless network, has anybody tried to get this working?

Thanks

Hi all,
I started testing openwrt on my debricked DG834GT and I am able to boot the router but it seems that there is no chance to write on the flash: I can't change root passwd or start webif.

Log:

Well in the end I succeded in building such an image, because my CFE version only supports tftp or web interface.

The requirements:

1.  The kernel image needs to be compressed with broadcom lzma
2.  In the image rootfs has to be first then kernel image
3.  All the CRC's in the image tag have to be correct.
4.  The kernel image has to start at 0x100 fold address
5.  The rootfs has to end at a 0x10000 (erase block size) fold address
6.  You need to create your own rootfs_data in bcm963xx-flash.c
Specific for davolink CFE
7.  The markers for jffs  0xdeadc0de are not allowed to be part of the image otherwise a modification of the flash
    is seen and the backup is installed

@ misteroX,

0x00010100-0x000cb6f8 : "kernel"
mtd: partition "kernel" doesn't start on an erase block boundary -- force read-only
0x000d0000-0x003effff : "rootfs"
mtd: partition "rootfs" doesn't end on an erase block -- force read-only
mtd: partition "rootfs" set to be root filesystem
mtd: partition "rootfs_data" created automatically, ofs=220000, len=1CFFFF
0x00220000-0x003effff : "rootfs_data"
mtd: partition "rootfs_data" doesn't end on an erase block -- force read-only
0x003effff-0x003fffff : "nvram"
mtd: partition "nvram" doesn't start on an erase block boundary -- force read-only

Thereis something broken on last updates, i have same problem.
when mtd driver atempts to create partitons, all are read-only and rootfs_data must be writable.

@ lamaatje,
Great news!!!, nice to see you again.
Can you post your bcm963xx-flash.c?
What tools do you use to create images?, i have tried with broadcom tools but they put rootfs before kernel.

Hi,

This error is caused because you are building the firmware without loading the firmware for the b43xx driver (broadcom wireless), you can fix it creating a folder named ..build_dir/linux-brcm63xx/linux-2.6.27.7/firmware/b43 which should contain the firmware extracted from the broadcom proprietary driver. Yo can find how to do this in http://linuxwireless.org/en/users/Drive … cefirmware.

I think the problem with the filesystem is different. I understand from previous posts you have recovered your router flashing a CFE from an asus model. I think it's quite possible that the actual hardware in both routers isn't the same. For example I am using a comtrend 536+, and this one uses a 29lv320 flash. If I load the CFE form a different router it might have a different flash chip (which I think is described in CFE), and so the hardware addresses for the filesystem would be different.

Hi t3l3m4k0,
can you tell me what trunk revision boots correctly and is able to write on the flash?

Thanks
Misterox

hi, misteroX
for me, builds up to 13370 are working fine.
lastest build, i think,  do not take good values to create mtd partitions (only read-only).

salut

@ neubauten,
maybe you has reason, but because early builds are working fine?

Thx.

(Last edited by t3l3m4k0 on 1 Dec 2008, 19:03)

i think this change:
@13379         [13379]       4 days      florian       [brcm63xx] bcm63xx MTD driver cleanup and fixes: - convert to …
don't like my router, specialy i think with "roundup" function.

Many thanks,
I will download trunk 13370 and I will check on if it will work.

Hi t3l3m4k0,
the revision 13370 boot without problems on my DG834GT.
I can change the password, and maintain the changes to reboot.

Hi t3l3m4k0,
are you able to use adsl feature of your router with this firmware (13370)?
And if so how have you done it?
