uClinux on the PSP? Well, we saw it awhile ago… Haha!

Developer and PSP Hacker, Jackson Mo, continues keeping the Linux on PSP project alive. Dedicated is a new website for the latest uClinux PSP port. Details concerning installation and compiling the kernel, your own apps, busybox etc… can be found at the source link. Don’t worry, a binary image of the kernel is provided below.

Major features:

• uClinux kernel 2.6.22-uc1. There have been substantial improvements from kernel 2.4 to 2.6 (one of which is the preemptible kernel that performs low latency operations). However, MIPS machines with no mmu (like Allegrex) are not yet official supported by the latest uClinux distribution. Therefore the kernel needs some serious patch up before it can be loaded on PSP.
• A configurable loader. The loader’s behavior is controllable through a config file, similar to vivi or uboot. However, it only runs on the 1.5 kernel/firmware thus users may experience problems with firmware 3.71 m33 or higher without applying the 1.5 kernel patch (3.71 m33-2).
• Busybox 1.7 armed with loads of utilities running on linux. Again, the original version needs to be patched up before it can run on PSP.
• A serial driver controlling UART3 (the remote control port on fat PSP) allowing you to open a SIO console on the PSP or to use any terminal program on your PC to act as an emulate keyboard when you are using virtual terminal. Up to 6 virtual terminals are available on PSP. Use +/- buttons to switch between terminals.
• A simple Framebuffer driver enabling virtual terminals to be displayed on PSP’s LCD screen.
• A new block device driver giving you accessibility to the Memory Stick (Cool!). By default, disk ms0 will be mounted to /ms0 after system startup, and there could be ms1 or more had you Memory Stick been divided into multiple partitions.
• A joypad driver allowing linux applications to acquire input from PSP buttons.
• A On-Screen Keyboard facilitating fast input in the linux environment, and also serving as an example of how to use the joypad driver.
• A patched mips toolchain allowing your to build your own program running on this Linux port.

Download the pre-compiled uClinux package which contains a loader, a config file, and that binary image of the kernel I mentioned earlier. Extract the archive into directory GAME150 on your memory stick. Then run the loader from the XMB just like any other homebrew.
