To run software on the router, it needs to be compiled for the MIPS processor onboard the router. The best/easiest way to do this is to use precompiled packages, although if one is not available you’ll need to compile it from source.

Hi Jeff
I have another question. I know DD-WRT is a linux system, and I use winscp copied a xclient in my router. everytime I run that program, it just stuck there. should I compile that softwre from source?

Try posting a topic about this on the forums (http://mightyohm.com/forum/viewtopic.php?f=2). I think one of the guys over there has done memory mods to his GC/GU. Unfortunately not everyone keeps checking the comments here, so sometimes the forums are a better option to get help.

There is some information and links here:

http://mightyohm.com/forum/viewtopic.php?f=2&t=51

The process involves using the OpenWrt build environment (the same you would use to build a new boot image, etc.) and creating a custom Makefile for the package you want to cross compile.

I also suggest posting a question about this on both the forums here as well as over at openwrt.org. There may be someone over there who has already done what you are trying to do!

Hi Jeff, thanks for your reply!
Are there any tools suitable for cross compliation job?

Your doubling RAM capacity is interesting.
The R66 is to enable the A12 (add more addressing, as the RAM doubled)
How about the nvram?… Is there anything to be set for the WL520GU?
What is the speed of the RAM required? 100MHz? 133MHz? 166MHz? 200MHz? I can see much of 100MHz – 133MHz, but rare 166MHz – 200Mhz for this type of chip (CMIIW).

Anybody had this mod successfully?…
Steps with picture would be a great help…

Cross compilation is not for the faint of heart. I think there is a post about it in the forums, but I have yet to find a good step by step guide. I have been able to cross compile some fairly simple programs, but it was somewhat painful.

your work is amazing!!

I have a asus wl-520gc, and i want to cross-compile h3cclient into the firmware. how can i do that?

1) Solder in R66 a resistor with same value as the other resistors (R91-R105) around the SDRAM chip;
2) Remove the SDRAM chip and put one of these instead:

(Note the usage of pin 36, in comparison to the original one:

3) Enjoy double ram capacity;
4) From your pictures that seems to be the board physical limit for the maximum addressable ram size.
