Hi! I'm newbie to this whole psp programming, so please be patient :) I have a problem with a prx, I'm putting it on ma ms in seplugins folder I set up evrything, but for some reason plugin's not working. This is the code:

main.c:
Code:
#include <pspsdk.h>
#include <pspkernel.h>
#include <pspctrl.h>

PSP_MODULE_INFO("psplugin", 0x1000, 1, 0);
PSP_MAIN_THREAD_ATTR(0);

int module_start (SceSize argc, void* argp) __attribute__((alias("plugin_entry")));

int plugin_dump_file(){
    SceUID fd= sceIoOpen("ms0:/plugin_pspain.dat", PSP_O_WRONLY | PSP_O_CREAT | PSP_O_TRUNC, 0777);
   
    if(fd < 0)
        return -1;
   
    int a=1;
    int rc;
    rc= sceIoWrite(fd, &a, sizeof(int));
    if(rc < sizeof(int))
        rc= -1; else
        rc= 0;
       
    sceIoClose(fd);
    return rc;
}

int plugin_thread (SceSize argc, void* argp){
    SceCtrlData pad;
    sceCtrlSetSamplingCycle(0);
    sceCtrlSetSamplingMode(PSP_CTRL_MODE_DIGITAL);
    while(1){
        sceCtrlPeekBufferPositive(&pad, 1);
        if(pad.Buttons != 0){
                if(pad.Buttons & PSP_CTRL_LTRIGGER){
                                int res= plugin_dump_file;               
                        }
                if(pad.Buttons & PSP_CTRL_RTRIGGER){
                                break;
                        }       
        }
        sceKernelDelayThread(100000);
    }
    sceKernelExitDeleteThread(0);
    return 0;
}

int plugin_entry (SceSize argc, void* argp){
    u32 func= 0x80000000 | (u32)plugin_thread;
    SceUID thread= sceKernelCreateThread("plugin_thread", (void*)func,0x30,0x10000,0,NULL);
    if(thread >= 0){
        sceKernelStartThread(thread, argc, argp);
    }
    return 0;
}


makefile:
Code:
TARGET = prx_test
OBJS = main.o

USE_KERNEL_LIBC = 1
USE_KERNEL_LIBS = 1

PRX_EXPORTS = exports.exp

INCDIR =
CFLAGS = -DNOEXIT -DFPM_MIPS -O2 -G0 -Wall
#CFLAGS = -DNOEXIT -DFPM_MIPS -O2 -G0 -Wall -fno-builtin-printf
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LIBS = -lpspdisplay_driver -lpspkernel

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build_prx.mak


exports.exp:
Code:
# Define the exports for the prx
PSP_BEGIN_EXPORTS

# These four lines are mandatory (although you can add other functions like module_stop)
# syslib is a psynonym for the single mandatory export.
PSP_EXPORT_START(syslib, 0, 0x8000)
PSP_EXPORT_FUNC_HASH(module_start)
PSP_EXPORT_VAR_HASH(module_info)
PSP_EXPORT_END

# Export our function
PSP_EXPORT_START(prx_test, 0, 0x0001)
PSP_EXPORT_FUNC_HASH(plugin_entry)
PSP_EXPORT_END

PSP_END_EXPORTS


I guess the problem lies in makefile or exports.exp, cause main.c is from modules tutorial...

ps. i'm using 3.52 m33-4

Are you sure this compiled without warnings?
Code:

                if(pad.Buttons & PSP_CTRL_LTRIGGER){
                                int res= plugin_dump_file;               

should be
Code:

                if(pad.Buttons & PSP_CTRL_LTRIGGER){
                                int res= plugin_dump_file();

Lol, it works... Thx man :)

I got another problem: my prx is not working when I add -lpspusb to LIBS in makefile. I checked it couple times and I'm 99% sure it's causing my prx to not load. Anybody knows this problem and knows how to fix it?
