Great!, I have two routers and I cracked both and one has 1MB flash and the other has 2MB flash. haha

I just wonder how much extra cost will be to put a 2MB flash in it rather than a crippy 1MB flash. Netgear is soooo cheap.

I think it is running vxworks rather than linux. It will listen on 192.168.1.2/vxworks.bin when booting. I hope the vxworks killer for WRT54Gs will work on this model.

I have two wgr614v6 routers with 1MB flash and 2MB flash respectively. I hope the support for 2MB flash model is on the way soon. I still do not give it up on my poor 1MB flash model.

With the firmware modification kit, can I chop down unused packages to make the firmware less than 1MB to fit into it. What I need is very basic, I am building a wireless bridge in my house. I hope the 1MB model will serve as a wireless repeater. That is all I want.

Can you see some light on it? Is this feasible?

I already tried chop it down to the max. No way it fits in 1MB, because you need to count space for cfe (128k at least) plus nvram (64k) which lefts you with little more then nothing.

Sorry, not possible.

I checked all 4 (four) of my WGR614v6 FCC-ID=py305100002 routers and all have (29LV800CTTC-90G) chip :(

I really wanted to make WLAN bridges out of them. I wonder if anything can be done with these...

Only way would be to replace the flash chip.

The four stand points are removable. Just try to uncover them. Then four screws will appear.

Do you know how to get such flash chips? My wife is reallllly good at installing chips (she gets a PhD there, Very Happy).

Can we find the V1600chip somewhere easy to reach?

Don't have a T5 screwdriver handy at the moment so will try to find one and report back as to what size my V6 flash is.

Thanks.

ok fellas, I got same router, MX CBTC 2meg flash chip,

Am I right in thinking that we need a dump of flash chip in order to proceed any further? Or is it OK to dump DD-Wrt onto this router?


Anyway I want to dump my router flash and post to you guys do whatever you need to do with it, only problem not sure of Jtag pinouts on router,

Have 12 pin header, like this one -
Code:
http://www.jtagtest.com/pinouts/wrt54

but not sure what correct pinouts are
(ie, are they the same or not, how to test pinouts before attaching jtag???)
, can make non-IC jtag cable no problem if this is what will work, right just 5 pins need hookup to Jtag?
(TDI,TDO, TMS, TCK and GROUND)

Ok anyway thanks fellas and hopefully can do this no problem Wink

ok I tried make jtag, pretty sure its all good, hooked up to modem and nothing,

Firstly tjtag wont detect
then if I do skip detect and use fc:09 it just hangs forever,

So how can I be sure I hooked jtag to right pins?
Also kinda sure something is hapeneing when I use jtag soft as the router LEDS stick on "power" and "test" and the wlan flashes occasionally, and as soon as I switch off the soft it goes and carries on flashing like normal loadup.


I could have the flash chip lifted and read on Willem but that wouldnt be able to get done for few days, I'm not bothered about breaking the flash chip as I can get another same one but I really just want to make sure I have full flash dump of original flash before messing about so I can always revert back to norm, and I'd rather do it without lifting/willem as thats a little bit of unneccesary mission!

The 12-pin header on the WGR614v6 is not a JTAG port, but a Serial port.

Hey m8, thankyou lots for that reply!!

Can you answer couple more things, if you dont mind,

which are pinouts for
gnd, 3.3v, tx, rx? (I can probly work these out with multimeter though right?)

With serial console access is it possible to make dump of flash (perhaps way to read address byte for byte and write little script to record output? I know this is possible with similar type broadcom based device with console access, although not always reliable method)



Finally I dont have spare router of this to donate right now, but I have means to share relevant info with the router I have so as progress can be made on this front,

I have means to have the chip (mx flash) lifted, read and replaced, so I can have a dump of entire original flash, and test various flash files you can give me. It will be couple of days from now but I can get that done.


If you can help me I just not sure of everything that is going on here, I have a lot of reading to do round here to get on point, ontop of any real work I have to do lol!

What is issue regards VxWorks? makes it a problem? or there is already solution for this? Things like this I dont know about I am sorry, but the simple stuff lol I can help.
