TomatoUSB

F7D4301 is already support by 54 version for dual band but need update nvram setting for Lan ports config.

F7d4302 is basically the same the F7D4301 but with a 100M ethernet switch.

I want to know when F7D4302 will be supported by tomato. It is very strange that it stop just after CFE.

Thanks for Tomato USB's great work. It really make tomato different.

Same problem with F7D3302 here. It also crashed at the same spot.
Almost as though Tomato crashes on Belkin routers without the Gigabit switch in the bootstrap code.

The full source code, build tools and build script for Belkin are available here:
http://www.belkin.com/support/opensource/

They added a few more while I was typing this post. F7D3301,F7D3302,F7D3402,F7D4301,F7D4302,F7D4401,F7D4402

I hacked the Makefile script in Belkin's 1.0.0.18 and made some progress. The modified script replaced target filesystem compiled by Belkin's source code with the one from Tomato Build 54 just before it is compressed and prepended by bootloader . This is not unlike what they do in a cooking show on TV to pull out the semi-finished product from the oven.

It made it all the way to a shell prompt, so something funny is in the Tomato bootstrap.

Here is part of the serial console log:

Tomato is broken because it can't find the Ethernet as it is grafted on top of Belkin's kernel. Unfortunately, the complexity for fixing the Tomato source code is a bit beyond me.

you should configure kernel to support the Ethernet card that router has before flashing it onto the router..

cd linux && make menuconfig

;)

The kernel I used was from the Belkin source code for my router model, so my assumption was any drivers that the router needs should have been there. The Belkin boot sequence was set to use sbin/preinit which isn't present in the Tomato, so it probably aborted without loading the modules(?) Anyway, that experiment was to test the build process and try to isolate the problem to kernel/bootloader.

I am going to reverse the grafting direction for the next experiment. i.e. modifying the Tomato build script and see if I can boot up Tomato correctly by using the Belkin init code and their boot loader.

Disclaimer: I am a linux noob and I don't normally use linux nor have I compiled a linux kernel in more than 12 years until last few days.

something funny is in the Tomato bootstrap.

Actually, something's funny is in the Belkin bootstrap.

They changed the standard TRX signature in Broadcom SDK by their own - individual for every router model! I hate when they do it… It's better than Netgear using an additional checksum in the middle of the flash - but still bad since it requires a bunch of extra code in the kernel and in the flash procedure to determine the model and check for different signatures. I wonder what Netgear and Belkin are trying to achieve by doing this - make it harder for open-source firmwares to support their routers? Well, if so they almost succeeded - I feel I just don't have enough time to workaround all this crap.

Ok, rant mode off :)…
If anyone's willing to try a test image on Belkin F7D4302/F7D3302/F7D3301 (only one of these 3 models for now), and if you know how to de-brick the router if things go wrong, please PM me.

This line of router product is for the average users, so they change the headers to "discourage" the users from putting in the wrong versions. But then again, they also switched the processor in F5D8235-4 from Atheros (v10xx) to Ralink (v20xx) and lastly to Broadcom (v3)!!

There are DD-WRT mini firmware that are specially compiled for each model. It rewrites the header for new firmware loads on the fly so that future ones are no longer model specific. Flashing via the DD-WRT mini is one way of avoiding model specific versions of Tomato firmware.

Thanks for looking into this.

Nope, flashing via DD-WRT won't help to avoid anything (other than creating a special image that will only be different from a regular one by these 4 bytes) - the firmware still has to do all the same stuff that dd-wrt does - otherwise CFE will prevent it from booting up.

Anyway, already did all of that - I just don't like the code getting more and more ugly with every one of these "special" cases.
Unless I missed something it should at least boot up - now I need someone to test it. Sent you a PM.

The good news is that the new load booted up and even can access the Tomato webpage for the first time. However, I saw the following 4 lines on the console:

cp: can't stat '/proc/webmon_recent_domains': No such file or directory
cp: can't stat '/proc/webmon_recent_searches': No such file or directory
cp: can't stat '/proc/webmon_recent_domains': No such file or directory
cp: can't stat '/proc/webmon_recent_searches': No such file or directory

After that the webpage is no longer available. Took a long time to load the main page and all I have are the text on the left hand side:
Tomato (beta)
Version 1.28
tomato
System
Wan
LAN

I tried a webCFE NVRAM erase and that didn't help. Linux is still available from console.
Please let me know what other things you want me to try.

Send you more feedback in PM. I guess I should skip PM for feedbacks and post here instead.

The webpages no longer available after being accessed.
Overwriting firmware and reflashing does not bring the webpage back.

Found the "wirless" with the matching MAC as my router. Managed to connect to it wirelessly. I can access external webpage via the router (doubled NATed) with its WAN connected to my old WRT54.

- Very good wireless coverage on default setting. I can pickup 2 bars from one end of a long hall way to the opposite end when the router is. My WRT54 has the same signal strength, but set to only 5mW!!

LED command in console does not do anything.

Update:
It could have been my netbook because I was chnaging the network setup a lot when flashing/testing Tomato. I have since rebooted it and it seems to be able to access the Tomato webpage fine now.

Yet another update:
Also tried it on a desktop with 1 Ethernet card. Seems also ran into same issues, but when I clear Firefox's browser history and cookies setting, it started to work. Netbook still messed up.

More update:
Seem like everything is there working.

Good job!!!

I think my Tomato webpage issues might be interactions of proxy server on my LAN. I have not messed around with IP table or routing. I only set the browsers of my machines to use the proxy, but bypass it for local addresses.

The netbook was the only one that is not going through the proxy server as I have to change the subnet a lot from Belkin's vs Tomato's vs my own LAN.

If the netbook is using the proxy, everything works fine. The strange thing is that I have been using the same setting while using factory firmware, DD-WRT, webCFE, TomatoUSB on WRT54 and they all seems fine.
