I have commited revision 2395, which should fix all the problems.

I have rerun toolchain.sh fully and am able to run binaries produced with the SDK.

yep, it work ok now.. thanks!

great, I'll update and report back!

I recently decided to upgrade the sdl and the libraries on 2 of my computers. The installation of the toolchain and the libraries went ok on both cygwin and ubuntu boxes. I have recompiled a couple of sdl game ports and that went ok too, but the resulting executables wont run on psp. I don't see any...

Well, the beauty of using frameworks like SDL or lua is that you don't have to worry too much about caching patterns and other low level stuff of this sort..

perhaps, there is a need for a benchmark program, which is bundled with the toolchain or particular libraries...

While moving some of my projects from old cygwin box to the tiny, ubuntu-powered asus-eee I noticed some weird stuff: Apparently the same project, compiled with "fresh" sdk/libs yields ~ 30% slower executables. I am not sure if this has anything to do with platforms or sdk/libs versions.. ...

I have not tried to write to sio - have no need for that..
Reading seems to work ok though.. I have no problems plugging in/out the gps receiver on my M33 - 3.71-2 slim psp..
You can probably detect whether the plug is in/out and re-init the port if that status changes..

My bad, somehow I thought you just wanted to boost the voltage with one of those RS232-TTL converters..

Seriously - look at how many threads are all noobies trying to figure out how to get CygWin to compile the toolchain. I like to joke that those threads make more than half the total number in this forum. :D In their defense, I must say that it's a huge pain in the a$$ to setup cygwin on most system...

funny read :-) But seriously, perhaps the sticky on top of the PSP forum section should give some disclaimer and guidelines on what to post/expect as well as some redirection suggestions for people, not fitting in.. This way a lot of misunderstanding, embarrassment and noise can be avoided in the fu...

check the latest (0.520) version of MapThis.. it does it if ran on 3.xx firmware..
The source code is included with the release..

Actually, the latest version of mapThis (0.520) enables speakers even if the phone plug is in (no cutting of the audio plug tip required).. The code can be found here: http://www.dcemu.co.uk/vbulletin/showthread.php?t=79825 The code works on ta-79 and slim psp (that I have at my displosal) as long a...

Setting the K1 fixed the problem.
Thanks a lot J.F. & dot_blank!

i ment do not do that in that same module do the loadstart in the siokernelprx (which should be all kernel stuff) dot_blank, I am a little confused: I already dumped all the kernel stuff in to a separate module: sioprx.prx.

I tired it with "PSP_MEMORY_PARTITION_USER" - it gave me same results :-(
Any other ideas?

Hi, I am having problems with interrupt handling for serial IO port. Basically, the code (below) works fine in kernel mode on the phat. The sio reads work on the slim too, but they don't seem to wait for the interrupt/timeout and return right away, thus making a very tight loop. I don't see any erro...

try installing without psplinkusb and then install it separately if needed..
just remove 009-psplinkusb.sh from scripts directory in the toolchain

I think those errors have something to do with SDL and or some windows flag that you need to pass to make...

@mypspdev: Below is somewhat modified code for sio sample that you should be able to run in 3.71 on slim... main.c #include <pspkernel.h> #include <pspdebug.h> #include <pspdisplay.h> #include <pspsdk.h> #include <pspctrl.h> #include <stdio.h> #include <string.h> PSP_MODULE_INFO&#40;"SIO_TE...

Just an interesting observation... I spent a couple of hours trying to make the sio sample run under 3.xx in M33 3.51-4 but the code would always crap out @ pspDebugSioInit() even though all kernel stuff was moved to a separate prx.. Then I ran same code on the slim 3.71 (finally got the remote cont...

IMHO, the PSP-290 GPS sensitivity issue is mostly due to interference that some PSP boards produce... You can improve sensitivity by distancing the receiver from PSP with extension cord (pc-mobile.net made one specificaly for that purpose on my request).. Another way to go is to play with board cloc...

Actually, I only need the sound through the speakers so this hardware trick works fine for me... Basically, I just want to be able to use speakers while using the serial port for gps receiver communication...

it appears that chopping off the tip of the audio plug connector does the job.
the serial port is still on while the speakers are not muted...
just make sure that you leave the other 2/3rds intact...

Can you post the code, so perhaps other people will be able to compile/link it?

this would be super!

Does anyone have any ideas on how to achieve it?
Apparently, it's possible in Talkman..

Now you can use the sony GPS with your wonderful Map This! homebrew.

Great !

I released a version of MapThis with PSP-290 support.

I finally got this thing working... Apparently, the 2.71's usbgps.prx has a bug in it... I tried the prx version, bundled with MapPlus and it worked..

You can comment out those test print lines - I was just trying to to print buffers for those numbers and try to figure out why I would get 355.**** instead of -73.**** make sure that test.dat is not empty and is in the same directory as your executable..
