OpenWrt on the Sony PS3 Game Console The OpenWrt build will create both a 1st stage PS3-Linux image suitable for programming into the PS3 flash memory, and a 2nd stage PS3-Linux image suitable for loading via bootloaders or the kexec utility. The 2nd stage image is convenient for testing new builds. It can be loaded from disk, USB device, or the network by an existing Other OS bootloader. After the 2nd stage image is tested and found to be good, the 1st stage image can then be programmed into flash memory. It is recommended to use this method during development to avoid corrupting the flash memory contents, which requires a reboot to the Game OS to repair. Known good Other OS bootloader images and installation information can be found here: http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ The 2nd stage image file is bin/openwrt-ps3-vmlinux.elf. It can be loaded with an entry in the bootloader config file. It has no initrd file. The 1st stage image is named bin/otheros.bld. It can be programmed into flash memory either from Linux or the Game OS. From Linux, use the command: ps3-flash-util -w otheros.bld From the Game OS, use the menu item 'Install Other OS'. Tips on how to recover your PS3-Linux system when it hangs up or no longer boots can be found here: http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-howto/ps3-boot-recovery-howto.txt To alter the kernel command line options, run 'make kernel_menuconfig' and go to 'Kernel Options' -> 'Initial kernel command string'. The default video behavior is to autodetect the monitor capabilities, which should work for most monitors. More info on video modes can be found in the man page of the ps3-video-mode utility.
Petitboot - kexec based bootloader Petitboot is a kexec based bootloader. It supports graphical and command-line front-ends. The command-line front-end can be used over telnet. Petitboot can load kernel images and initrd files from any mountable linux device, plus can load from the network using TFTP, NFS, HTTP, HTTPS, and SCP.
