New binary release on ps2dev.org. Mainly fixes added such as fixing the wifi code to support something other than the first configuration (oops) and endian fixed for mac (double oops). Also added a thread monitor so you can get information on the terminal when threads are created, started, exited or deleted.

Thanks for this even better version TyRaNiD.
I hope kernel module debugging support will be in the next version?

A little "bug" in the documentation.

Name thstun
Synonym mn
Arguments uid|@name
Description Stops then unloads a module in one operation.

It should be modstun, not thstun

In response to the problems with usb "read cancelled (remote disconnected)", I've been trying to set things up and was having the same problems.

I haven't done enough checking to be sure, but it appears it involves either some changes or bugfixes in libusb.

Updating to at least v0.1.11 of libusb seems to fix the problem.

I've noticed a couple people mention gentoo (and I too use gentoo sadly). The version of libusb currently marked as stable for x86 is 0.1.10a, so you'll have to use the ~x86 branch.

Tyr: I know it's not as heroic as writing a driver, but telling people to update libusb seems a lot easier no? ;)

Finally found the time to try it, and YEAH THAT MAKES IT GO :D :D :D
libusb 0.1.11 makes it all good :))))

Thanks all. Awesome program!

I tried usbhostfs_pc on OS X 10.4 and I was getting the same "disconnected" results as Shazz.

I've tried .12, .11 and .10 versions of libusb, but with no luck. Setting USB_TIMEOUT to 10000 stopped the "disconnected" message, but as soon I telnet and send a command, I get the following:

The only bit of progress I can manage is to launch PSPLINK after starting usbhost_pc and telnetting. I get the "host0:/>" prompt displayed in telnet, but then I get the same bus error as mentioned above after submitting the first command.

Hmm is there any chance of getting OSX to core dump ? I am obviously doing a misaligned read somewhere (and without a mac and osx to try it on it is kind of difficult to fix). If you can core dump or run it under gdb then tell me where it crashes and ill see if I can work out what I am doing wrong.

urchin · Joined: 02 Jun 2005 Posts: 121

I've not managed to make it core dump yet - I can't try until later today. In the meantime, does the CrashReporter log provide you the necessary info? (This is using 0.1.12 of libusb btw, I can build it with previous versions if that helps)

This might be helpful too - I set the "usb_debug" var to a higher value:

OK, it appears that the problem is with libusb and not PSPLINK. I tried libusb versions .12 -> .8 and the included tests don't even work!

On the bright side, YAY!

I downloaded a pre-built libusb from here, http://www.ellert.se/twain-sane/, and it works! I'm not sure what the problem is, but it works with this version.

Nice app TyRaNiD! :)

That is good, all I can say is "bloody libusb"!!! ;)

I'm having more problems :( and I can't be sure libusb is the cause.

My test program reads in a text file a character at a time using fread, which is then printed to the screen. After what appears to be 1024 characters, the beginning of the file starts to be printed again.

The problem first appeared when reading the file over usbhostfs. I then copied the file to the memory stick and changed the program to read from there. Starting the program from PSPLINK produced the same corrupt results.

If I run the program without using PSPLINK it works as it should. I'm assuming PSPLINK patches the IO functions somehow, but I can't work out where to test further.

Shazz · Posted: Sun May 07, 2006 4:29 am Post subject:

So based on great urchin's discoveries and libusb distrib, I played with psplink/usbhost for a few hours...
Basically it works perfectly with some limitations :

- fread freezes after some calls, use sceIoRead instead
- impossible to load a PNG from host:

If your files are on ms0:, the usbhost driver is not used (psp will go directly to ms0:) so you won't get any problems.

I now seem to be having problems with fwrite.

Ach, my bad - I was accidentally linking against psplibc. Things are going better now.

I'm also seeing weirdness with libpng though. It's not failing, but all debug messages are truncated after loading an image. I'll dig into it when I get chance.

Shazz · Posted: Mon May 08, 2006 7:13 am Post subject:

a friend told me he has the same issue with the Windows version while loading png. So it is not only mac related it seems.

I'll say it once again.. PSPLink is an awesome piece of work.

One question: is there a way to log the comms in the included term app or should I look at adding some code to do so? (Im thinking session logs with the filename as the date/time and markers for PSP sent and user sent messages)

TyRaNiD · Joined: 18 Jan 2004 Posts: 918

It is something I have considered but never got around to doing it. If of course you feel like writing something to do it then I dont mind integrating it into the repository :)

Oh and shazz any chance you can dig up a simple example of the png loading failing so I can look at it, unfortunately pretty much everything people have said which fails in psplink I have been unable to replicate. Having some clear examples of broken code might aid me in tracking down problems.

For loading PNGs I use code I yanked from elsewhere. I'll have a look tonight to compare the differences.

TyRaNiD: that and tab completion are what I miss, Ill have a look but I cant promise alot (ie: you will probably have to be the code cleaner-upper if you really want me to add this stuff - but I'd be more than happy to do a lions share of the typing and trial/error if you dont feel like it)

The other day I decided I wanted to go with the SIO, I had been having some problems with the USB shell crashing and I had hoped SIO would solve my issues. Unfortunately, I got a whole new set of issues (and yeah, I tried wifi but it was a crashwhore too with my pci card in AP mode).

Working with the sparkfun adapter (from here) I am able to receive from the PSP at any baud, but I cant send if I set the term/psplink at anything higher than 9600bps. Its odd because I am able to bridge the rx/tx at the psp voltage and have the PC talk to itself fine, but any time I try and send to the psp from the PC both Rx and Tx light up but nothing happens (the psp does not seem to be getting the sends at all). Is anyone else seeing this type of behavior in SIO shell or has everyone moved on to USB and wifi shell?
(riden pointed me at this thread - is this still an issue with serial comms?)

Tab completion is something on the list somewhere but really I am not sure how best to implement it in the current implementation. For host stuff I could probably query the usbhostfs_pc stuff through pcterm and do it on the client and I could replicate the command list inside pcterm but that seems ugly. Ill try and add logging sometime soon :)

As for SIO stuff well using pcterm with SIO seems to be potentially unreliable due in part to the lack of flow control as pcterm fires off the entire the command in one go. Also it seems to not like being used with other shells enabled. The best mode for sioshell is to only set sioshell and set pcterm in the ini to 0. That way characters are sent as soon as they are read to the psp eliminating most of the flow control issues. But for that youll want to use something like minicom or tutty, pcterm will still operate in a line based mode.

even just tab completion for the command list (instead of using help/pdf every time one wants to find a command) and basic/common paths would probably be enough for most everyone.

SIO: I considered that pcterm could be the problem, its why I have been doing all my testing on this with Tera Term. I disabled everything except SIO shell (annoying that I have to hold the power button and reboot every time since it wont accept any commands over the serial) - but basically I'm down to two things and trying to figure out which is the culprit: hardware or software. So far it is a mixed bag, as I have no real answer and it could go either way. I have a Max3232 on its way, so maybe that will help me sort it in the end.

TyRaNiD · Joined: 18 Jan 2004 Posts: 918

I've added basic logging to pcterm by the way, you have to log an entire session (and only output is logged) by specifying it on the command line with the -l option. Best you are going to get atm :P

Have you tried the SIO example in pspsdk with your serial cable ? Youll need to make a call to set the baud rate differently, but at least it would indicate whether it was a hardware or software problem. I guess it could be something weird like an dodgy connection on the PSPs RX pin which just about works at low baud but completly dies at higher speeds, though that seems unlikely.

I've been using PSPLink (0.9f) for a while now, and it's a really great tool.

So i've been working on something in the PSPLink environment, and everything's working great, however if I run the same eboot in the XMB, I start getting problems. Some of my integers seem to gain random (usually high) values, which makes the app. unstable. I don't know that much about memory allocation, but it sounds like I've got something leaking into those integers and corrupting them. If I define them as static, then they act as normal, but this isn't the best solution, and I'd like to know how I can debug this problem or simulate what PSPLink does to fix this problem.

Thanks.

EDIT: I think I may have found the leak, after adding code to dRead as suggested in the related thread, it seems to have stopped the random values. I have a bad feeling that the compiler is just re-organising the RAM addresses though...

Hi,

i try to use gdb. Any ideas what's going wrong there ?

optixx00, strange that you are not getting any results from the PSP side of GDB, stupid question but did you enable usbgdb in the configuration file ? Although it really shouldn't matter, if you had enabled wifi it probably would fail before it got anywhere, or at the very least have printed a different IP address (maybe).
