Hi everyone. I have recently ported another uClinux of version 2.6.22-uc1 onto PSP. On top of the serial driver and the framebuffer driver, there is a new joypad driver enabling apps to read input from PSP buttons, and the a block device driver allowing linux users to access the Memory Stick in linux. And I have established a website for it: http://jacksonm88.googlepages.com/linuxonpsp.htm

Or visit http://jacksonm80.googlepages.com/linuxonpsp.htm which is a mirror site.

Thanks to everyone who have offered me help on this.

PS: Due to the bandwidth limitation in the original server, here is another location where you could download uClinux.zip and extract it to game150/ for a fresh try:

I never knew Office was that broken.. but I think you need to use a different app to create that webpage, all but the first paragraph are just images and so none of the links work. http://jacksonm88.googlepages.com/image699.gif

[killerrabbit]

Very nice man but can you give a good link to download . please.

P.S : I have found how to get it go to this link

http://jacksonm88.googlepages.com/uClinux.zip

and it runs . very great work.

This is wonderful,the only thing is that using the dpad on the phat is extremely unpleasant. It would be much better to use the analog for input.

[IM back!]

first of all id like to say thanks for porting linu× to the psp.

some recomendetions id like to make are:

1. targus universal driver. (ill might be able to make one myself but ive never made a driver before even thow ive coded c++/c for 2 years now.)

2. your not using the psp's FPU.

3. it might be possible to use the PSP's ME as another CPU (dual core PSP :) ). as it runs at the same clock speed and has full memory acssses

I must not be doing something right... I've got it to boot just fine, the only problem is that in trying to use the OSK, I can't access the keys on the diagonals, making it VERY hard for me to type commands in ;)

Phat PSP btw.

Ok, I have updated the webpage, which should have gotten rid of the weird problem now.

Btw, I have also updated the memory stick driver a little bit so that it now can flash the LED during reading or writing.

Enjoy!

Sweet. Now all we need is Wifi or USB Gadget for connectivity. Porting the IR keyboard driver is a fairly trivial task.

Is uClibc-0.9.15 the only thing that needs to be patched for the toolchain? If so I can add the PSP to openembedded fairly easily...

[brk3]

Yes this is amazing work :) Cant wait to get home and try it! Thankyou and look forward to seeing where else this can go

[Oguz286]

It says the bandwith limit has exceeded. Could you post it somewere else? I'd really like to try it :)

Ok, I have just uploaded uClinux.zip to this location. http://myfreefilehosting.com/f/a94c114520_0.9MB

For those who are eager to have a try, just download the zip and extract it to game150. Later I will renovate the webpage so that everybody can access.

[noquarter]

You could try talking to the guys over at dcemu,they host several developers projects.
Thanks again for working on this M.Jackson,could you provide a link to your prebuilt toolchain?

[gambiting]

I also uploaded it on my own server - http://sklep.vivexpol.pl/uclinux/uClinux.zip
It's 24/7,and with no limits.Glad I can help :D

yeeahhhh, very cool!

Jackson, i am trying to build my own boot image but whithout success..

i am get the last uclinux-dist-release (not cvs)
i am try to patch 2.6.22-uc0 (not find uc1)
i am try to patch your kernel.patch
i am try to patch your kernel.patch without 2.6.22-uc0

and i am try here now, how can i build this port?
some howto? tutorial?
please, give us more informations of developing of the port

(sorry for bad english :))

I think there is really no much difference between building a standard kernel and building this port. All you need is just having your toolchain setup properly in preparation and applying this patch before compilation. In case you never built a kernel before, here are some general steps:

- have the toolchain installed properly (something like mipsel-linux-XXXX);
- under the root directory of the kernel source tree (not the root directory of the distribution package), config your kernel with commands like "make ARCH=mips menuconfig" or others; or you could just start with the config file I posted (by replacing the .config file with my kernel.config, and then run "make ARCH=mips menuconfig" again);
- build the kernel using "make ARCH=mips CROSS_COMPILE=mipsel-linux- vmlinux.bin", after which you will get the binary image of the kernel. The loader actually supports compressed images, thus you can further shrink down the size of the kernel by using "gzip -9 /share/psp/vmlinux.bin". Don't forget to change the loader's config file to point to the compressed image.

In addition, to produce a fully functional system, you may also need to build busybox as well as constructing the initial root fs - a directory structure that contains /bin /dev /proc and so on. Building busybox will help construct some of those, but you still need to manually create some of the devices under /dev just like the ones you saw in the pre-compiled version.

I really hope I can explain everything right here, but it is just that the details of all these are totally beyond the space of this post. Generally, I think maybe you could try to get started by preparing the toolchains first (one for building the kernel, the other one for building busybox and other apps). And then maybe you could try to build an application of your own, which will certainly familiarize you with all these stuff. Once you get used to it, you can have it done with little effort.

Can we use the uClinux port for the ipod (ipodlinux.org) on this ?

Because it also uses the 2.6 kernel i think.

Would be cool, playing some games etc etc (i suppose music wont work).

Hello Jackson,

I already have the toolchain compiled in my system
I forget the flags 'ARCH' and 'CROSS_COMPILE'

your kernel.patch its for whitch kernel? uclinux-dist with 2.6.x? 2.6.2x-ucX? original 2.6.22 kernel?

first i will compile kernel, later i will try to build the rootfs..
one step of each time

Very Thanks

Is it at all possible to add persistence to the initial file system? Perhaps with the Cygwin way and save it in the directory the loader resides in (or perhaps a sub-directory within it), or a tar archive or similar method. ms0 is a bit difficult to type in, and links in /bin and such aren't saved as far as I can tell. Theoretically, everything the end-user might want to link to can be set up in a shell script, but it would have to be run at boot manually each time.

Also, it would be neat if you could add a hibernate-like system, dumping the RAM to disk somewhere and using that instead of the default if it exists.

I know these ideas aren't real important at the moment, but it's just "food for thought."

Fun idea... PSP toolchain....

... on PSP :D Lol
