I want to re port uClinux to the psp so that it can be updated and then hopefully (when I get to it and have time) add block devices, network interface, and other things. Plus if i'm not able to do all that stuff I can still run scripts that will tar.gz and other stuff for me on my psp

[wankel]

I like this idea very much. What kind of help are you looking for?

[coolkehon]

I'm having trouble getting the buildroot installed with the correct options at the moment. So in general just about everything.

[wankel]

have you tried looking at jacksons files? that may help you get started

[coolkehon]

yeah I'm still going thru them. rebuilding each time takes time ;)

[wankel]

gotcha =) well i dont know how to get started, but if theres anything you'd like for me to do/try just let me know

[coolkehon]

Well for now I'll have to come back to this project (about 2weeks) because I'm working on other projects and I spend a week on each and rotate them around (this being one) but as to where you should start. I suggest you try to get buildroot installed first which I am having trouble with atm and make sure you are using mipsel just like in uClinux. Basically I want to have an updated busybox and maybe some more options like an image.ext2 file that is mounted so that stuff can be saved. So if it could call a startup script on the memory stick then I could have it mount some of the things etc.

[wankel]

A little late but I believe I got the buildroot successfully installed. What now sir?

[coolkehon]

would you mind posting the steps you did to get it installed correctly

[wankel]

coolkehon, I just used this guide to do it. Very detailed and seems to work well. Let me know how it goes.

[coolkehon]

this is the error i get
I'm on x64 ubuntu linux 9.10
although I had this problem in 9.04 also

[wankel]

Did you install the "install" and "build-essential" packages before compiling? These usually arent included in a default ubuntu installation.

These specific errors lead me to believe that you may not have them installed.

[coolkehon]

still doesn't work and I had build-essential installed already. I'm going to look through the make files but if you have any suggestions i'm open for them. Also since your on x64 would you mind sending me your buildroot distro already compiled. So that I can see if maybe that will work. I've got a ubuntu one and dropbox account if you want to transfer that way also

dropbox can be found here

[coolkehon]

what make command did you issue.
The Blog says "make source make" but
http://jacksonm88.googlepages.com/linuxonpsp.htm
says "make" and also doesn't add the part about editing the config in the make menuconfig

I'm trying just make which is downloading the linux kernel. I'll see what that does and get back to you. If you have anymore ideas let me know.

edit:
this is the output from that. It also fails

[coolkehon]

i was able to download the prebuilt toolchain of buildroot for the psp and it works as far as gcc giving an output (basically it will run on x64). But when I try to compile a helloworld.cpp it gives me the error

[wankel]

The buildroot I compiled failed since it wont do anything apparently. So I downloaded the prebuilt one and got the same error as you. To fix it, I downloaded the mipsel "libc6-dev" package and copied the ctrl.o and ctri.o files from that to the specified location. Now I'm getting this error:

[wankel]

Okay I got it to compile but I cannot execute the program. When its compiled I get two files, one hello and one hello.gdb. When trying to execute the hello file I get this:

[coolkehon]

well I got it to compile an executable some how but on uclinux (psp) it says something similar to BIN not FLAT. So i'm guessing it wasn't a flat executable like uclinux on the psp needs

[wankel]

AHHH I got it! I compiled a hello world app in the toolchain, ran it on the psp in uclinux and displayed the damn hello world. Heres how I did it:

Step 1:
Download the precompiled toolchain and unpack it.

Step 2:
copy the following files from /staging_dir/usr/lib to /staging_dir/mipsel-linux-uclibc/lib:

crt1.o
crti.o
crtn.o

Step 3:
Write your source file and place it in /staging_dir, and compile with the following:

/home/USERNAME/staging_dir/usr/bin/mipsel-linux-gcc -I/home/USERNAME/staging_dir/usr/include -static -Wl,-elf2flt -fno-jump-tables helloworld.c -o hello

Let me know if that works for you :)

Too much Linux / BSD tech support during M-F 8-5. And I am so dead tired when I get home, the spirit of a project often requires me to start on Saturday morning early. Very glad to hear you guys are getting started, I think we can make a more updated version of PSPLinux and hopefully get it compiling 2.6.32-rc5-git3, or at least 2.6.31.

BTW, I am a Gentoo user, just so we have all our distros on the table. I also keep an Ubuntu box around for things that install easier with a debian descendant, for instance the toolchain. : )

[coolkehon]

great work wankel. Thanks mine too compiles.

I have mine in /usr/local/psplinux and I created a workspace folder in there for eclipse and other projects. I'm not very good at makefiles but I made this one and it works.
Also I added /usr/local/psplinux/usr/bin to my path so I don't think it actually needs to be in the staging dir

edit: It doesn't need to be in the staging_dir because it can find mipsel-linux-gcc from the path.

[coolkehon]

it seems helloworld can't accept command line args though

[coolkehon]

i havent figured it out yet and i don't know assembly language yet either. Just some c/c++ and no kernel programming experience. But while thinking it over i think it may be a problem with busybox. because grep, etc accept commands from the terminal.

@wankel. do you think you could try to get busybox recompiled
because i'm busy with some stuff atm

also here i found these files
http://psplinux.berlios.de/wiki/Downloads
they should work

[wankel]

I can give it a whirl, ill let you know how it goes.
