 |
|
Hi, I am having a problem with the SDL in the PSP 3000.
I made a small code but did not work, the PSP crashes and restarts, or even the emulator (JPCSP) can run this example, the emulator reports the this error:
10234 [user_main] ERROR memory - write32 - Invalid memory address: 0x8AC PC = 089016C0
Below is my source:
main.cpp:
| Code: |
/* Test SDL OpenGL support. */
#include <stdio.h>
#include <stdlib.h>
#include <SDL/SDL.h>
#include <SDL/SDL_opengl.h>
#define SCREEN_WIDTH 480
#define SCREEN_HEIGHT 272
static GLfloat delta = 1.0f;
static GLfloat angle;
extern "C" int main(int argc, char *argv[])
{
int done = 0;
if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_JOYSTICK) < 0)
{
return 1;
}
if (SDL_SetVideoMode(SCREEN_WIDTH, SCREEN_HEIGHT, 0, SDL_OPENGL | SDL_FULLSCREEN) == NULL)
{
SDL_Quit();
return 1;
}
glViewport(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(-2, 2, -2, 2, -2, 2);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
while (!done)
{
glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
angle += delta;
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glRotatef(angle * 1.32f, 0.0f, 0.0f, 1.0f);
glShadeModel(GL_SMOOTH);
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_TRIANGLES);
glColor3f(0.0f, 0.0f, 1.0f); glVertex3f(1.0f, 0.0f, 0.0f);
glColor3f(0.0f, 1.0f, 0.0f); glVertex3f(0.0f, 1.0f, 0.0f);
glColor3f(1.0f, 0.0f, 0.0f); glVertex3f(0.0f, 0.0f, 1.0f);
glEnd();
glFinish();
SDL_GL_SwapBuffers();
}
return 0;
}

You're obviously trying to write at a forbidden address. I suggest you to use psplink, or if that doesnt work, disasm your ELF with prxtool and check for the address that causes the exception (0x089016C0). That should give you the hint about which function triggers the excep.

I don't see a PSP_MODULE_INFO call in your code so if there is no error about this when you compile (first time you type make compiler complains about PSP_MODULE_INFO, second time you type make it compile) maybe you are using an old version of SDL that was in kernel mode, for the newest firmwares it must be in user mode (newest SDL is in user mode, I think).
But I'm sure the crash is because in your makefile you aren't building it for the newest firmwares (missing BUILD_PRX =1).

I found the error using the psplink (disasm), the function that the error is occurring is the glViewport, but I think it makes sense, I compiled an example of using GLUT Nehe (PSPGL) and worked in PSP3000, i noted that the SDL uses the PSPGL, I believe it was for work, another detail that I noticed was that when I moved my code of structured (functional) oriented to the object, simply did not work more, the same error occurs in memory, someone knows the reason?
Grateful. |

| Maybe the link order... the GL libs should be AFTER the SDL libs seeing as he SDL libs use the GL libs and not the other way around. |

I tried to reorder the links but did not work ... i rewrite my code to try to use only 2D, but also did not work in PSP, but the Emulator JPCSP work (an error occurred -> (3890 [user_main] ERROR hle - Unmapped @ import 0x08800000), but if you choose to continue the game normally works, because the game hangs in PSP3000.
main.c | Code: |
#include <pspkernel.h>
#include <stdio.h>
#include <stdlib.h>
#include <SDL/SDL.h>
#define SCREEN_WIDTH 480
#define SCREEN_HEIGHT 272
PSP_HEAP_SIZE_KB(20400);
SDL_Surface* screen = NULL;
int SDL_main(int argc, char *argv[])
{
int done = 0;
if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_JOYSTICK) < 0)
{
fprintf(stderr, "Unable to initialize SDL: %s\n", SDL_GetError());
return 1;
}
screen = SDL_SetVideoMode(SCREEN_WIDTH, SCREEN_HEIGHT, 32, SDL_SWSURFACE | SDL_FULLSCREEN);
if (screen == NULL)
{
fprintf(stderr, "Unable to create OpenGL screen: %s\n", SDL_GetError());
SDL_Quit();
return 1;
}
//while (!done)
{
SDL_FillRect(screen, NULL, 0x00FFFFFF);
SDL_Rect r;
r.x = 50;
r.y = 30;
r.w = 100;

SDL_FillRect(screen, &r, 0x00000000);
SDL_Flip(screen);

SDL is there any way out to make a simple 2D game?
Thank you! |

I'll say it once again, maybe you are using and old version of SDL.
Try your code with this changes (little, but they are):
main.c
| Code: | #include <pspkernel.h>
#include <stdio.h>
#include <stdlib.h>
#include <SDL/SDL.h>
#define SCREEN_WIDTH 480
#define SCREEN_HEIGHT 272
PSP_MODULE_INFO("SDLTEST",0, 1, 0);
PSP_HEAP_SIZE_KB(20400);
SDL_Surface* screen = NULL;
int main(int argc, char *argv[])
{
int done = 0;
if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_JOYSTICK) < 0)
{
fprintf(stderr, "Unable to initialize SDL: %s\n", SDL_GetError());
return 1;
}
screen = SDL_SetVideoMode(SCREEN_WIDTH, SCREEN_HEIGHT, 32, SDL_SWSURFACE | SDL_FULLSCREEN);
if (screen == NULL)
{
fprintf(stderr, "Unable to create OpenGL screen: %s\n", SDL_GetError());
SDL_Quit();
return 1;
}
//while (!done)
{
SDL_FillRect(screen, NULL, 0x00FFFFFF);
SDL_Rect r;
r.x = 50;
r.y = 30;
r.w = 100;
r.h = 75;
SDL_FillRect(screen, &r, 0x00000000);
SDL_Flip(screen);
}
return 0;
} |
makefile
| Code: | TARGET = SDLTest
OBJS = main.o
PSPSDK=$(shell psp-config --pspsdk-path)
PSPBIN = $(shell psp-config —psp-prefix)/bin
CFLAGS = -O2 -G0 -Wall -g
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBS = -lz -lm -lSDL -lGL -lpspvfpu -lpsphprm -lpspaudio -lpspgu
BUILD_PRX =1
PSP_FW_VERSION = 500
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = SDL Test
include $(PSPSDK)/lib/build.mak |
And this is the resulting EBOOT.PBP:

I didn't run it in a PSP3000 (I don't have one), but it works fine in a Slim, just try it and see what happens (observation: to exit you must turn off complete the PSP, because there is no exit callback implemented).
