It is great that you have got the keyboard functioning Chris.I have an idea that if you were to some how implament may help other people who don't have an IR keyboard.
Looking at my desk while browsing this post drew my eye towards my HP Jornada 720

which has its own keyboard and IR port,this gave me the idea that mabey i and others could use a WinCE or Linux device like this as our IR-keyboard instead of going out to buy another gadget to clutter our desks.

The cache is enabled.

Its a _very_ inefficient implementation at the moment, all invalidate + writeback commands writeback and/or invalidate the WHOLE cache.

But at the moment we almost never need to explicitly writeback or invalidate it.

Hey, I'm having some really horrible problems trying to compile the kernel. It seems no matter what I do the xiptech toolchain won't make properly, it needs to download some files such as binutils and the kernel source headers, unfortunately the source headers are no longer hosted where it tries to download them from. And the kernel itself is having a multitude of problems that I haven't even tried figuring out yet. is there any way you could host the new kernel somewhere, or even better send me a compiled toolchain for cygwin(however doubtful that may be) Thanks in advance

You have to download these missing files from somewhere else and put the archives into the "source/dl/" directory of the toolchain installer.

Try these locations:
http://ftp.gnu.org/gnu/binutils/binutils-2.12.1.tar.bz2
http://www.kernel.org/pub/linux/libs/uclibc/old-releases/uClibc-0.9.15.tar.bz2
http://ftp.gnu.org/gnu/gcc/gcc-3.2/gcc-3.2.tar.gz
http://ftp.azc.uam.mx/mirrors/gnu/savannah/files/openap/kernel-headers-2.4.18.tar.bz2

Then comment out all calls to "wget" in the toolchain script. It will then use the local copies (or just change the urls in the script accordingly).

To get the script to execute I also had to comment out the lines starting from
"# Hack things to use the correct shared lib loader" to
"# Fixup where gcc looks for start files to prevent glibc stuff leaking in..."
in the script. I'm not sure what they are supposed to do but they wouldn't execute on my system and it works without them for me.

Another important thing could be that the version 3 of gcc cannot be compiled using a gcc 4.x, that means you have to install a 3.x version of gcc before trying to compile the gcc 3.2 crss-compiler. Before I learned that I always got weird compilation errors in the second compilation pass (with gcc 4).

One note to Cygwin: I also tried installing the toolchain under cygwin, but gave up after several tries. It always ended with "internal compiler errors" and therelike. I'm also not sure if the kernel will compile at all on a non-case-sensitive file system.
Then I tried under a real linux with the changes mentioned above and it compiled without a problem.

thanks, that should get it working I had tried commenting out that section but I had put the other libs into /build instead of source. I'll try it on a real linux shell after I get it onto my other partition, but I was hoping to get this working before I took the time to do that. again, thanks for your help

Just an FYI, if anyone took nice notes when building the Xiptech toolchain and wanted me to put them up on the site, I wouldn't say no... :)

I'm trying to get the kernel toolchain to build. Building the cross compiler and binutils seems to work. But I'm missing elf2flt sources or binaries.

This location seems to be commented out by purpose:

Wow, are you over-thinking it or what? Ignore the bogus patent. IR keyboards just send a stream of data each time you press or release a key. The simplest keyboards simply send a single byte x for the key press, and 0x80|x for the key release. Others may put synch bytes before or after the key data.

The Palm 3169ww sends a couple more bytes than many, most of which can be ignored. The data from the Palm is a sync code (0xFF, 0xC0), followed by the primary keycode, followed by the primary keycode check byte (if x is the keycode, this is ~x), followed by a secondary keycode, ended with a closing sync byte (0xC1).

Key Down = 0xFF, 0xC0, K1, ~K1, K2, 0xC1

All you want is the K1 or K2 from the stream. Pretty simple. Key ups are the same -

Key Up = 0xFF, 0xC0, K1|0x80, ~(K1|0x80), K2|0x80, 0xC1

The Belkin F8U1500 send data like this -

Key Down = 0xC0, group, Key, 0xC1
Key Up = 0xC0, group|0x80, Key|0x80, 0xC1

The older Palm Wireless (not the 3169ww above) sends -

Key Down = Key, 0xC1
Key Up = Key|0x80, 0xC1

The Pocketop sends -

Key Down = Key
Key up = Key|0x80

If the key up was the last key up (no more keys held down), it repeats the Key|0x80 once.

The Targus IR keyboard sends -

Key Down = Key
Key Up = Key|0x80

So you can see that getting keys from an IR keyboard is fairly simple. Some more simple than others.

I have been watching this project for a while now, checking up on it now an then and I think the progress that has been made lately is brilliant.

I'm thinking of starting up a website for this soon (forums, news, downloads, svn repo, etc), I'm just wondering what everyone here would think of this.

Hi all,

I have managed a speed up bootloader from Chris. The old one is load
from srecords (about 3 mins loading time). I changed it to load from
statically linked binary that reduce the loading time to about few
seconds.

Attach psp_bootloader_fast.tar.gz, (put uclinux.bin to root directory
of the memory stick and folder psp_bootloader to GAME directory.
Please try it out and let me know you want the source. (cantona@cantona_NOSPAM.net - remove _NOSPAM)

Thanks
Cantona

nice job. The Srecords were a carryover from when I was transmitting the kernel over the serial port. The checksums on every line made handling comm errors nice and simple.

Is anyone looking into direct hardware access of wifi or memory stick? Those are the two most important things standing in the way of this being "useful".

Hi there, first off all a big congratulations to everyone work on this project. I would like to say that I'm very interested in this project, and would like to take it to a better stage of development.

But before talking about what it is that i would like to do, its better if you people know who i am; I'm currently a student studying programing, and Linux. I'm also a Creative Director, working on my art related works within a group, involving production and post-production. Other fields of understanding include hardware & electronics.

----
Current projects that I'm working on includes;

Nokia Linux (i thought it would be a good idea to port to)
http://sourceforge.net/projects/nokialinux

DSLinux (Porting Apps, Beta Testing, Documentation & Webserver)
http://dslinux.org/

Project Ashes (OpenSource & Free Content Distribution)

I keep seeing messages in my inbox "Hey! Can I help?" And I expect it to be a coder offering assistance with the wifi or memstick, but its just another offer to "run the web site."

This project needs developers. At the moment, I seem to be the only person doing any significant work. Just recently someone updated the bootloader and I'm psyched about that; its the first contribution I've gotten.

For this to have any usefulness whatsoever, it needs WIFI support and Memory Stick support. A web site is the _least_ of my concerns. Once this does something interesting, I'll setup a wiki and the page will make itself.

But if you want to set up a page about this kernel that has no end user applications and has no support for any non-transient storage, by all means, go ahead, but please stop emailing me for my "endorsement".

well hardware is not at all documented you know.

to use firmware kernel functions and to drive directly hardware are quite a different challenge.

So i wouldn't expect for a lot of people to be versatile enough about creating from the scratch a driver without any precise knowledge about hardware registers.

hlide, everybody who is even potentially capable of developing on this project is fully aware that the lack of documentation makes it difficult.

So, thanks for stating the obvious. Its about as useful as an offer to "run the web site".

Do you just like complaining?

I gotta say you all have done some cool things.

Please don't let it go to waste, i am no kernel guy.

But I can do applications, and if the base (ex: linux and devices) are in place then people will code for the PSP like crazy.

the eboot scene is already doing a BUTT LOAD of homebrew, but its all hack because its not really native to the OS.

With a true linux in place this all changes.

Now as far as coders go, well... Maybe taking a look at the homebrew guys might help. They know all kinds of info about the PSP.

Maybe we should bring them in on this.

I think this is very awesome.

BTW after alittle poking around i found this:

http://pspupdates.qj.net/PSP-Phone-Tool-v1-00/pg/49/aid/86580

Here is a description:

The PSP Phone Tool homebrew application, allows PSP users to send text messages to over 20 different phone servers via the PSP's WiFi connection and built-in web browser.

So, here it seems is a way to find out howto program and to talk to the WiFi and maybe more..

Just my thoughts.

Thanks,
John

... That is just a web portal, nothing to do with Linux or an EBOOT. And EBOOT's are native to the PSP...
