Petitboot

Setup Buildroot

First thing we need to do is setup our buildroot. Most of this is ripped from how-to's around the nets.

1. Install Dependencies:
   

   $ sudo apt-get install quilt build-essential subversion libncurses5-dev zlib1g-dev gawk flex
   
2. Clone Gits:
   

   $ mkdir petitboot
   $ cd petitboot
   $ git clone git://foxbrew.org/ps3linux/petitboot/openwrt.git
   $ git clone git://foxbrew.org/ps3linux/petitboot/openwrt_packages.git
   

Foxbrew openwrt links are dead. Mirrors at https://github.com/jumoog/openwrt https://github.com/jumoog/openwrt_packages. Just replace the links with the GitHub ones.

3. Link packages:
   

   packages to link are in the file ps3_petitboot_howto
   
4. Copy the configuration:
   

   $ cp ps3_petitboot_config .config
   
5. Build:
   The first time you build, a cross-compiling toolchain will be downloaded and built. This takes a very long time. Subsequent builds are much quicker (~10 minutes).
   

   $ make V=99
   

EXTRAS

WIFI(SLIMS)

you can use / to search in menuconfig (thanks jevin)

1. cd into package folder
2. clone my ps3-jupiter fork on github
3. enable base system -> wireless-tools, kernel modules-> wireless drivers -> kmod-ps3-jupiter, and Network -> wpa-supplicant(if needed see WPA below) as builtin (*) in menuconfig
4. enable networking support->wireless -> wireless-extensions as builtin (*) in kernel_menuconfig (you should highlight wireless to make all the other options appear)
5. modify kexec to unmount the new modules also (ps3_jupiter_sta ps3_jupiter)

(If you choose (M) it will be compiled but not included in the dtbImage. Useful for debugging a module that hangs the kernel :D)

$ cd package
$ git clone git://github.com/DirtyJerz/ps3-jupiter.git
$ cd ..
$ make menuconfig
$ make kernel_menuconfig
$ cd target/linux/ps3/petitboot/base-files/etc/init.d
$ nano kexec --modify MODULES="ps3_jupiter_sta ps3_jupiter.."

WPA

If you use WPA2 as I do, you can apply these patchs to package/base-files to enable a the generation of a wpa_supplicant.conf file. It will also add 2 lines to rc.local to automatically connect to your router on boot.

  Makefile.patch - http://pastie.org/2624949
  image-config.in.patch - http://pastie.org/2624956

put those files in package/base-files and apply the patches with

$ patch < Makefile.patch
$ patch < image-config.in.patch

you can now enter your SSID and wpa2 PSK in menuconfig and wpa_supplicant.conf will be added to /etc in petitboot.

Compiling petitboot (graf's method)

• I use petitboot to install and boot Linux from internal HDD of my PS3.
• With petitboot, you will be able to install/boot a Linux kernel from USB, HDD, BD or network.
• Compiling petitboot takes a very long time ( actually, it take a long time during the very first compilation, because it compile the powerpc64 toolchain too, but after that, is you re-launch another compilation, it's "fast" )
• On my Arch Linux x86 it doesn't build without patches
• I created a new openwrt git repository which contains my patches and PS3 NOR and VFLASH block device drivers

At this moment, the official GIT server is down :
