if you are using psplink, you can use stdout and stderr to output on pspsh

EDIT: ah ! kernel prx, oh well never mind.

Well enabling the Instruction Stepping Mode in the Debug view, allows me to step over any function withow breaking the program, even the sceDisplay* or sceGe* ones, but it does show a "No source available for "" " warning with these. so it is like I said : In fact, I need to deb...

@hnaves
to be sure to understand what you posted. Is "load_unk" to be called with prgidx as the third index in program headers ? the one of type LOPROC+a1 (0xFFA1) ? if so, that's a great help, thanx !

When i start debugging the app there is some error with the sceDisplayWaitVblankStart function, it complains about something like "GDB is unable to find the start of the function at 0x880a408", i have managed to Step into other sce functions by pointing to the corrent source path, but doe...

Some progress but just some. I need to close FireFox so PSPSH can run properly (displaying a prompt like "host0:>") . And yes debugging is not working properly. When I tried cube.prx (-g -O0), it seemed to work. But with my source (-g O2), I have kind of erratic behavior in the source wind...

by the way option "-v" doesn't work for pspsh.exe. The options parser doesn't consider -v as valid option, why ?

pspsh doesn't seem able to connect psp as i cannot see any shell prompt. I type "verbose 2" in usbhost_fs.exe console and I got those messages after plugging usb on psp : Connected to device Bulk Write dev 0x347c8, ep 0x2, bytes 0x23ca6c, size 4, timeout 1000 Bulk Write returned 4 Bulk Rea...

I don't understand... I was able to debug cube.prx as stated in your eclipse.pdf yesterday or yesterday but one. but now, when I run pspsh through Eclipse, I have a void console, no message at all. I can type and be sure that they are executed but i cannot see anything except from what I type. I als...

pspSdkSetK1(0) should make it seem like kernel mode, but I dunno whats wrong. why ? sceKernelIsUserModeThread() is probably just inquiring whether if the thread was created as a user thread regardless if we are running a kernel-mode function through syscall. And $k1 register is just a general purpo...

Ok found, I just need to have a start.bat (to launch Eclipse for PSPSDK) which setup the environment the right way : @echo off echo Setting up environment for PSPSDK... set PATH=C:\pspsdk\bin set PATH=%PATH%;%SystemRoot%\System32 echo Starting eclipse... call "M:\dev\eclipse\ecl...

Heimdall, I'm trying to use Eclipse but I have a problem. I installed your last toolchain. I have Eclipse with Qt Integration that I launched I follow your instructions in your .PDF file about Eclipse. When I try to build I get this : **** Build of configuration Default for project Spinning Cube ***...

For instance, JGE : void JGE_Gfx::Gfx_FillRect(int x, int y, int width, int height, PIXEL_TYPE color) { struct VertexColor* vertices = (struct VertexColor*)sceGuGetMemory(2 * sizeof(struct VertexColor)); vertice...

For what I can see : putPixelRGBA8888(int x, int y, int c) : LUI %0, %hi(current_frame_buffer) SLL $a1, $a1, 11 // y' = y * 512 * 4 LW %0, %lo(current_frame_buffer)(%0) SLL $a0, $a0, 2 // x' = x * 4 ADDU $a0, $a0, $a1 // offset = x' + y' ADDU %0, $a0, ...

PutPixel, GetPixel : i'm not sure using GU to do so would accelerate anything, it may be worse indeed.
I guess DrawLine, DrawRect, etc. can benefit from GU.

huh this is just an example to show how we could handle C++ exception to throw when an hardware exception occurs (access to null pointer, divide error, etc.) which are not catchable with the actual psp-gcc. I think if we could tweak the source of exception.prx (not sure about the name) which is a ho...

Ok let's imagine we have a kernel prx wich installs a exception handler and that we can call a handler individually for each different cause : void exc_install_handler(int cause, void (*handler)(int, exc_t *exc)); Basically, the general exception we installed through a kernel prx will be called when...

I edited heavily the previous post so the stub generator can handle the case when one of first two instructions in the original function contains a relative branch instruction. You need a .S file to contain your stub to overwrite (for each original function to patch, you need a stub function of 8 in...

branch control instructions are : J, JAL, JR, JALR, Bxx, etc. NOTE: if one of the first two instructions in the original function is a relative branch transfer, you'll have an issue because you need to recompute the target offset so you need a stub like it if insn2 is a relative branch instruction :...

char Sens[10]; ... if (Sens == "Droite") This is not how you compare strings in C. You use strcmp. It's probably working only because your compiler is making all the instances of "Droit' point to the same constant string, but you shouldn't rely on that...

if you need a mutex, why not using those : sceKernelCreateMutex sceKernelDeleteMutex sceKernelLockMutex sceKernelLockMutexCB sceKernelTryLockMutex sceKernelUnlockMutex humm... those functions are only available in the SDK or DA SDK meaning I don't know the method signature... more work to do... ok,...

"sb $zr, 0($v0)" ==> "*((char *)v0) = 0;"

but v0 = 0, so you're trying to writing zero through a null pointer somewhere in your code.

if you need a mutex, why not using those :
sceKernelCreateMutex
sceKernelDeleteMutex
sceKernelLockMutex
sceKernelLockMutexCB
sceKernelTryLockMutex
sceKernelUnlockMutex

that was what i thought hlide, and started to add a simple threading implementation to gcc based on an old haiku-os implementation that only tels gcc that this device can handle mutexes, however when i throw an exception the mutex locks everything (i guess i got it all wrong from the gcc barely exi...

If i'm not wrong, you need to provide a c++ exception handling implementation for PSP in gcc source. Gcc can generate calls to some functions and you need to implement them as they may be dependent on OS. As far as i know psp-gcc has no such implementation.

Yeah I know you could. But I know Sony's PRX sets up the media engine for decoding mp3 audio, or h.264 video. My question is, when the ME is in that state and decoding "media" can I still run my own code on it by using threads or some other method? Most probably the second processor for *...

what does TKS mean ?

NO,MAN. YOU CAN NOT FIND ANYONE USE phone modem TO ACCESS INTERNET IN CHINA .WE USED ADSL & digital cable modem INSTEAD OF IT MANY YEARS AGO. well, that's a great news, but i don't like your tone. It sounds aggressive to me. Avoid those capitalized words here. Anyway, don't expect a hardware RM...

Good to hear, so RM is clearly anachronous.

There's a problem, 95% of us aren't Chinese. What sites use RMVB these days? huh, when he said "millions of psp players' mind", he means Chinese people. And yes, it sounds as if Chinese people don't have the best access to Internet : mainly a slow phone modem instead of an ADSL or digital...

ME code is using "ldl" and "sdl" instructions (normally 64-bit version of lw/sw) heavily and in a way suggesting they are used for a very different purpose : testing if a controller is busy and transferring data from/to a controller. I wouldn't be surprised if it were a special i...
