 |
|
Hi, I'm an Italian developer (so sorry for my bad english :P).
I have a problem with a my PSP program. I can't access to Flash0 to write or delete files...
For example:
| Code: | #include <pspkernel.h>
#include <pspiofilemgr.h>
PSP_MODULE_INFO("TEST", 0, 1, 1);
int main() {
pspDebugScreenInit();
pspDebugScreenPrintf("Result");
sceIoUnassign("flash0:");
sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);
int ok = sceIoRemove("flash0:/dog.txt");
if (ok<0) pspDebugScreenPrintf("FAILURE");
else pspDebugScreenPrintf("SUCCESS");
return 0;
}
|
Even this simple code does not work! O.O
I tried the same code with the Flash1 and it works good... but with Flash0 it does not work in any way...
Do anyone know why?! Please help me :(
P.s.: File "dog.txt" exists, because I created it on Flash0 before running program ;)
I'm on CF 3.71M33-4. |

It will work if you do it like this,
| Code: |
PSP_MODULE_INFO("MyAppName", 0x800, 1, 0);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_VSH);

Thank you :)
But if I use that code, program works only if I insert it in PSP/GAME150...
I wanted to make it compatible with PSP Slim too.
Is there an alternative way, please? :( |

Well that's how I've been doing it and it works on Fat / Slim,
I have been putting it in GAME on the Fat PSP, |

If I put the eboot in GAME (on my PSP Fat) I obtain the error: 80020148...
It works only in GAME150 (I'm using 3.71 Kernel from recovery).
This is my Makefile:
| Code: | TARGET = hello
OBJS = main.o
INCDIR =
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LDFLAGS =
LIBS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Hello World
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak |
It's wrong? |

Add BUILD_PRX = 1 to the makefile.
VSH elf's are rejected in 3.XX kernel. |

This is my makefile,
I'm also using the 371SDK that came with 371m33-1
| Code: |
TARGET = flasher4V1
OBJS = main.o cfg.o
INCDIR = ../include
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS) -c
LIBDIR = ../lib
LDFLAGS =
LIBS = -lpspkubridge
PSP_FW_VERSION = 371
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = flasher4V1
BUILD_PRX = 1
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

Sorry, but it still does not work.
If I insert the eboot in GAME150 program works very good.
But in GAME and GAME371 PSP gives me the error "Impossible to..... (80020148)"
My main.c is:
| Code: | #include <pspkernel.h>
#include <pspiofilemgr.h>
PSP_MODULE_INFO("TEST", 0x800, 1, 0);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_VSH);
int main() {
pspDebugScreenInit();
pspDebugScreenPrintf("Result");
sceIoUnassign("flash0:");
sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);
int ok = sceIoRemove("flash0:/cane.txt");
if (ok<0) pspDebugScreenPrintf("FAILURE");
else pspDebugScreenPrintf("SUCCESS");
return 0;
} |
And Makefile used is:
| Code: | TARGET = flasher4V1
OBJS = main.o
INCDIR = ../include
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS) -c
LIBDIR = ../lib
LDFLAGS =
LIBS = -lpspkubridge
PSP_FW_VERSION = 371
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = flasher4V1
BUILD_PRX = 1
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak |
It works only in GAME150.
My PSP is set on Kernel 3.71 from Recovery... :([/code] |

This is a quick example of flashing a "test.txt" to "flash0:/vsh/resource"
It uses the 371SDK that came with 371m33-1
Works on 371m33 Slim/Fat,
Also works on 380m33 Fat but not yet tested on Slim but should work,
main.c
| Code: |
#include <pspsdk.h>
#include <pspkernel.h>
#include <pspdebug.h>
#include <kubridge.h>
#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include <stdarg.h>
PSP_MODULE_INFO("MyAppName", 0x800, 1, 0);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_VSH);
#define printf pspDebugScreenPrintf
int status;
int exist = 0;
char write_buffer[128*1024];
void check(const char* zFile) {
int fd3;
fd3 = sceIoOpen(zFile, PSP_O_RDONLY, 0);
if(fd3 < 0) {
exist = 0;
}else{
exist = 1;
}
sceIoClose(fd3);
}
int write_file(const char *readpath, const char *writepath) {
check(readpath);
if(exist == 1) {
int fdin;
int fdout;
fdin = sceIoOpen(readpath, PSP_O_RDONLY, 0777);
if(fdin >= 0) {
int bytesRead = 1;
fdout = sceIoOpen(writepath, PSP_O_WRONLY | PSP_O_CREAT | PSP_O_TRUNC, 0777);
bytesRead = sceIoRead(fdin, write_buffer, sizeof(write_buffer));
while((bytesRead > 0) && (fdout >= 0)) {
sceIoWrite(fdout, write_buffer, bytesRead);
bytesRead = sceIoRead(fdin, write_buffer, sizeof(write_buffer));
}
if(fdout >= 0) {
sceIoClose(fdout);
}
if(fdin >= 0) {
sceIoClose(fdin);
}
}
return 1;
}else{
return 0;
}
}
void Reassign() {
sceIoUnassign("flash0:");
sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);
}
int main(void) {
pspDebugScreenInit();
pspDebugScreenClear();
Reassign();
status = write_file("./test.txt","flash0:/vsh/resource/test.txt");
if (status == 0) {
printf("Source File Does Not Exist...\n");
}
if (status == 1) {
printf("Flash Complete...\n");
}
printf("Exiting...\n");
sceKernelDelayThread(1000000);
sceKernelExitGame();
return 0;
}

-edit-
I did not need all those headers but too lazy to remove them, |

Use this:
PSP_MODULE_INFO("Flasher", 0x1000, 1, 0);
PSP_MAIN_THREAD_ATTR(0);
You can run under kernel mode on 3.80 m33-4 (I tested it on 3.80 m33-4)
Tested on:
fat psp
3.80 m33-4
no 1.50 kernel add on
GAME folder
3.80 Homebrew Game folder on recovery.
AND
slim psp
3.71 m33-4
GAME folder
3.71 Homebrew Game folder on recovery |
