1. The 16MB flash chip is 100% recognized by the router, when I enabled jffs I ended up with 12.3MB of free space.
2. If I can get my hands on a 32Mx16 DDR I just might try swapping the DRAM again. Address line A12 is the highest on both the 16M and 32M because of the row/column scheme used for memory access. In theory it should work, the Broadcom flyer claims up to 128MB of RAM is addressable by the 5352 IC.
3. If you really want to try this I strongly suggest you get some low temperature solder thats specifically used for removing SMT parts. One source for DIYers would be ChipQuik. I have no affiliation with these people, and in fact I used a different manufacturer's product (same general product tho...). ChipQuik also has a fairly easy to follow set of instructions. _________________ WRT54GL modded to 32MB DRAM and 16MB Flash.
Awesome. Nice soldering job, too. What would the kind of gear you used cost?
The removal equipment wasn't too bad (around $1000 IIRC) and the soldering iron was another $500. Good thing it comes with the job, I wouldn't be paying that to mod a $60 router. :D
Honestly though, if you're reasonably good at soldering SMT parts you can do it with any decent temperature controlled iron. The two most important things are lots of flux and lots of wick. _________________ WRT54GL modded to 32MB DRAM and 16MB Flash.

Heh, you should have seen what my wife's iBook looked like when I got done fixing it. If anybody opens it in the future they'll probably say, "I can't believe this thing actually works!"
I need some more precise tools. :)
There's probably a market for someone who can max out a Broadcomm chip on a WRT-54G. I can think of some applications where I'd pay a couple hundred bucks for a mini solid-state linux machine that I could load a larger runtime environement onto, so if somebody wanted to setup a business and got good at it it might be worthwhile for many $60 routers. Heck, with perl or PHP it could make a pretty decent little high-availability webserver for small coin. It wasn't so long ago that 32MB made a nice webserver! _________________ Formerly participating under a pseudonym to counter an unjust Sveasoft practice.
Yeah, if you would sell modded wrt54gl's at a (modest!!) premium over the normal price, I would definitely be interested... _________________ If you use DD-WRT, you HAVE to make a donation! See this topic too: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=228
here in china, you can get tools to do that for USD$7.00. =.=
Perhaps. But they would probably work like $7.00 tools as well.
In any case, cost was not really the issue. If it were I would have just bought a more expensive router since this mod would have cost ~ $500.00 at my typical hourly rate (between the research and the actual labor), even though actual (out of pocket) cost was nothing. I had the DRAM module laying in a desk drawer, the flash chip was leftover prototype inventory from a three year old design and the tools are available any time I need them.
To be able to rework SMD components like this, and end up with such professional results, is my dream! Someday I will have the equipment necessary and skills to do this Wink.
Tools are less than 30% of the equation. Its mostly just practice/experience, and wrecking a lot of boards along the way.
So get out there and do something, unlike what your 'nick implies.

Problem is component cost in low volume. If I actually had to buy the parts it would have been ~ $20 for the DRAM and $17 for the flash (in single piece quantities, not including shipping costs, and most distributors that sell these parts have a $25 line item minimum...).
Add to that even a modest amount for labor and supplies (low temp. solder, regular solder, flux, wick, etc) it would probably end up doubling the cost of the router (I paid $65 for my GL).
How many people would be interested at that kind of price? Not many would be my guess. _________________ WRT54GL modded to 32MB DRAM and 16MB Flash.

Not me, no, that is true. But I think there IS a market even at that price, because I think that a DDWRT54GL with those extended specifications would be very well able to manage quite a large network; you would still have the value of a much more expensive router at a very low price. _________________ If you use DD-WRT, you HAVE to make a donation!

I went and found this thread just to post this information, so I hope it's useful to someone . I tried this out myself on a broken router I have and I was able to do it, despite me still being fairly new to soldering. I would be more hestitant to do it on a working device, but after a little practice it should be no problem. The biggest thnig is to make sure you don't force the chip off the PCB, as you may pull up the contacts if you do, leaving you with no option other than soldering to the traces to the broken contacts (something I had to do recently on another proejct.. not fun).
I've ordered this memory chip for now (it costs ~$6 in Russia).
What I'm not sure is - which timing specs should I buy?
Could you please provide more info on FLASH chip (timing and package specs) you've used as well?
Thank you in advance.
I do plan to put the 64MB chip too (it costs ~$15 here) - please report if you succeeded with MT46V32M16 chip installation. _________________ OpenWRT RC6 powered WRT54GL v1.0 (64MB RAM mod)
