==WAG54GV3 Firmware==
 
−
This tells u how to compile the WAG54GV3 firmware. This is written for unbuntu since all the newfags use that, but will prolly work with whatever if your not complteely tarded~
 
  
−
first downloads teh TI-toolchains-2_1_0-cy07.PROPER.tar.bz2 and WAG54GV3-AU_v1.00.22.PROPER.tar.bz2.
 
−
* extract TI-toolchains-2_1_0-cy07.PROPER.tar.bz2 and copy opt/ to / (there is probably already a /opt hopefully it wont copy over anything impotant. However usually mv just nicely merges two sets of files.. i think :p).
 
−
tar -jxf TI-toolchains-2_1_0-cy07.PROPER.tar.bz2
 
−
sudo mv opt /
 
  
−
* extract TI-toolchains-2_1_0-cy07.PROPER.tar.bz2 to your home dir. it will create the WAG54GV3-AU_v1.00.22 dir.
+
==bgfunct==
−
tar -jxf TI-toolchains-2_1_0-cy07.PROPER.tar.bz2

<source lang="c">

cd /WAG54GV3-AU_v1.00.22/src

#ifndef THBG_H
−
export PATH=$PATH:/opt/TI-toolchains-2_1_0-cy07/mipsfple/bin/:/opt/TI-toolchains-2_1_0-cy07/mipsfple-uclibc/bin/
+
#define THBG_H
−
(if you plan to work with the code alot, make mods, etc, might wanna add this to .bashrc or .login or such :)
+
−
./make.sh
+
−
This will make everything, hopefully. If your done you should have a file called upgrade_code.bin in the image dir.. (may be 1 directory up if you cd router'ed). If not see the troubleshooting section:
+
  
−
==onoes! teh fail :/==
+
typedef void(*_pBgStartFunc)(void); //Background Setup Function (called first)
−
if you gets:
+
typedef void(*_pBgUpdateFunc)(int); //Background update function
−
/home/isabella/ForL3x/WAG54GV3-AU_v1.00.22/src/linux/linux-2.4.17_mvl21/tools/7zip: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory
+
typedef void(*_pBgFinishFunc)(void); //Background destroy function
−
trys:
+
−
sudo apt-get install something with libstdc++-libc6.2-2.so.3? (sry i forget u_u)
+
  
−
What no bison?! if you gets:
+
typedef struct {
−
make[2]: bison: Command not found
+
_pBgStartFunc start;
−
trys:
+
_pBgUpdateFunc update;
−
sudo apt-get install bison
+
_pBgFinishFunc finish;
 +
void *bgdat; //background set specific data
 +
} thbg_t;
  
−
if you gets: (btw this is only necessary if your re-building after a previous build, but rly that it generates error messages and fuglys up your terminal should be reason enough to fix this...)
+
void thBgInit(void); //get everything ready
−
/bin/sh: rcsclean: not found
+
void thBgUpdate(int frame); //call this every vblank
−
trys:
+
void thBgStart(thbg_t *thbg); //call this to start a bg (will first stop any already running)
−
sudo apt-get install rcs
+
void thBgFinish(void); //stops bg, erases bg mem, etc
  
−
It may be useful to make each step seperately, helps finding error messages as it'll prolly halt abruptly. To do that first type this once:
+
void thUpdateBgPalette(uint16 *pal, int dstpal, int size);
−
cd router
+
void thUpdateBgSubPalette(uint16 *pal, int dstpal, int size);
  
−
and then type (one line at a time newbs):
+
#endif
−
make linux-clean
+
−
make linux-dep
+
−
make linux
+
−
make clean
+
−
make

−
make linux-modules

−
make install

−
make rom

make upgrade

Tbh, i cannot remember exactly, firstly finding the right toolchains and where to put it was a plus, then finding a few syntax errors in the main Makefile, and umm ummm, oh yah, finding that library file was pita mostly because i didn't get that it was looking for file to run 7zip and not link it or somethign and missing libstdc++blahblah, also installing bison and such...

This page can be used to experiment with the waki wiki ways

note to self: make a page on writing device drivers for libnds...

asdfgh!

some of meh programming values:

  • simplicity

things should be intuitive, easy to use. variable and function names should be self explanitory as much as possible.

  • consistency

variable and function names, methods, etc should follow patterns

  • modularity

individual components that can be used alone or in tandem

  • compatibility

components should work with each other as well as other '3rd party components'

  • familiarity

components should be based when appropriate on well known common concepts.

  • eat lots of leet onion

Huh @_@? How about: no one is perfect :p
