-OpenWRT on PS3
+OpenWRT on the Sony PS3 Game Console
-To install the built image, you'll need to copy bin/otheros-ps3-2.6.bld
-to a USB device, MMC card or CD image. The image will need to be placed
-on your media, at the path:
+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.
- /ps3/otheros/otheros.bld
+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.
-Then insert the media into the ps3, and navigate to 'Install Other OS'
-in the PS3's menu.

-Depending on your monitor, you may need to alter the kernel command
-line options. The default is to autodetect, which should work on most
-monitors. However, if you get a blank screen on boot, try changing
-(through make kernel_menuconfig) "video=ps3fb:mode:0" to
-"video=ps3fb:mode:1" for 480i, or "video=ps3fb:mode:3" for 720p. The
-possible modes are:

-Video mode ID:
- 0:auto mode
- YUV 60Hz 1:480i 2:480p 3:720p 4:1080i 5:1080p
- YUV 50Hz 6:576i 7:576p 8:720p 9:1080i 10:1080p
- RGB 60Hz 33:480i 34:480p 35:720p 36:1080i 37:1080p
- RGB 50Hz 38:576i 39:576p 40:720p 41:1080i 42:1080p
- VESA 11:WXGA 12:SXGA 13:WUXGA
+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.
- full screen mode: <video mode ID> + 128
- dither ON mode : <video mode ID> + 2048
+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:

+
+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.
