GC Linux - RootFS on SD + SDHC SUPPORT!!

[_Nold_]

Hi,

some time ago, i was thinking about GC Linux and WHY THE F*** i need a NFS to use it ^^
So i started creating a GC-Linux which has it's root Filesystem on the second partition of my SD-Adapter... I dokumented it pretty good (i think.. at least better than my other projects xD)

But i had trouble with creating a nice and usefull root FS, so i just used the one from MFE which is useable. You could even create one using debootstap with ppc binarys, but it becomes pretty big... so after some trys i got bored, since videos are not really playable.. but mp3 should be fine..


So here are the files:

Kernel is 2.6.32 with mikep5 Patch
The Documentation: http://www.gc-forever.com/wiki/index.ph ... otFS_on_SD
Needed Config files: http://nold.freeunix.net/devnull/Downlo ... config.zip (root=/dev/gcnsda2 - gc-linux.org wiki paths are wrong)
Dol-File + RootFS: http://nold.freeunix.net/devnull/Downlo ... pha.tar.gz

Here you can download the complete sourcecode if you don't want to search the files ^^

Here you can see it booting: http://www.youtube.com/watch?v=pQwy9SYk5TI


Hope someone has some use for it - everything can be modified as you want it and feel free to ask me for help.



//Edit:
As may some of you noticed did i finish a SDHC driver for GC-Linux
Here is now my Beta release, would be cool if some of you could try it out, and give me some feedback.

The 16/32 stands for the SPI Clock (Known from SWISS) and the a/b for the port of the SD-Card.

It's not really nice written but it works... but since i never did something like that before, i'm actually pretty pround on myself ^^

[liquitt]

nice to see you here!
you seem to be somewhat into linux etc. - wanna help develop a mikep5-like patch for a more up-to-date kernel?

[_Nold_]

I have got nearly no idea of kernel patches but why not

[liquitt]

gamecube is still present in the 3.x kernels that recently came out, but it needs a lot of patching
why did mike stop after mikep5

i created a googlecode for this. wanna get in? pm me your mailaddress

Hmm... on the one hand it would be a real interessting and cool project but on the other hand i don't see the point for doing that much work... in my eyes the GC-Scene is nearly dead, next gen is coming and the gc is not really powerfull to do anything usefull under linux..

the gc-scene is dead? your registration to this forum should've shown you that this is not true

[_Nold_]

Ok, you're right
So, let's have a try...

[emu_kidid]

thanks for the guide, I'll have to try it out

[_Nold_]

I just updated the guide a little bit... I wrote it really fast, so there are a lot of mistakes >.< sorry for that...

And i found the mplayer settings i think mfe uses:

Code: Select all

mplayer -slave -noconsolecontrols -quiet -nojoystick -framedrop -cache 4096 -subfont-autoscale 1 -subpos 70 -sub-fuzziness 1

[_Nold_]

I just noticed there are a lot of mistakes in my ducomentation f.e. the device node path's are wrong >.<
I will correct that tomorrow but for now i've got a working rootfs with mplayer, init, audio-ram-swap, fstab,...
Kernel.dol is included, too. Don'T forget to unpack as root, so the device nodes are created correctly!

I transfered my Documentation into the gc-forever wiki and updated it with right fstab and init-script

good job..
linked your wiki page to main page to make it easier for others to find

My Keyboard Adapter just arrived yesterday so could just try it out.. It only seems to work in Slot-1 what sucks a little bit because my viper gc needs a controller in no. 1 -.- but ok..
One Problem i had was mounting the root read-write, couldn't remount because "Device is busy".. same on the first partition vfat...
But i forgot that i compiled a kernel.dol with rw.. need to try that one..

And then i will start building a better rootfs. Think i will use debootstrap in first place...
Damn, i need a BBA ^^

[liquitt]

i need an autoboot - ssh enabled - ha cluster - gc-linux

[_Nold_]

Why HA-Cluster? High Performance

[liquitt]

i have this project called gc-cluster where i want to have 8 gamecubes with linux clustered and one management "server"

[_Nold_]

Wow thats kinda cool ^^ ..
My biggest problem is that i have no BBA. That makes testing really slow.. Trying to get one, but i think i need to join the collective order for the next year :/

[liquitt]

btw thanks for the tutorial but maybe you should add another one that makes use of your already compiled stuff etc.

on the bba: i can borrow one for the time being

[_Nold_]

Thanks a lot for your offer but i don't like to borrow things from others :/ ...

[liquitt]

also, some commands for example for SD card formatting would be useful to some

[_Nold_]

i used cfdisk for that, but you could even use gparted oder the drive-utilty that comes with ubuntu or mint (Which is really handy btw)..
i will take a look on that later ^^


I just wrote a short tut how to prepare your SD with fdisk and mkfs: http://www.gc-forever.com/wiki/index.ph ... with_fdisk

hf!

Noldor: You may add "force_keyboard_port=4" to your kernel command line, to avoid your viper-controller-switching-thingie.

[_Nold_]

thanks man! I knew there was something with 4! But i deleted it since i didn't hab a keyboard adapter before >.<

EDIT: I just recompiled with force_keyboard, rw and rootwait... seems to work good but keyboard @ port 4 dosn't work even if he says it's forced:

[ 6.119620] input: keyboard as /class/input/input0
[ 6.127626] gcn-si: port 1: keyboard
[ 6.135406] gcn-si: port 4 forced to keyboard mode
[ 6.143177] input: keyboard (forced) as /class/input/input1
[ 6.150805] gcn-si: port 4: keyboard (forced)

(Port 1 is my real keyboard...)

[infact]

Strange. For me it works like this:
Wavebird receiver in port 1, ps/2 keyboard adapter in port 4 and "force_keyboard_port=4" in the kernel command line.

[_Nold_]

Lol - now it's working for me, too.. that's strange
