Copy Files into Flash0

[Rinnegatamante]

In a PRX (for VSH), how i can copy a file from MS0/EF0 to F0? I tried this:

Code: Select all

void copyFile(char *basefile,char *nuovofile){
FILE *from, *to;
  char ch;
from = fopen(basefile, "rb");
to = fopen(nuovofile, "w");
  while(!feof(from)) {
    ch = fgetc(from);
    if(!feof(from)) fputc(ch, to);
  }

But PSP freezes...

P.S. Could a moderator move the topic? Wrong section... sorry...

You need to load an additional kernel mode module from your usermode code.
The kernel module then needs to perform the copy process

I'm creating a PRX, i don't need to use an another PRX...

Moved to the programming subforum.

I think you have to remount flash0 to get write access. Check this.

[Rinnegatamante]

I just tried to unmount and remount flash0 access but nothing is changed...

This is my code, now:

Code: Select all

void copyFile(char *basefile,char *nuovofile){
FILE *from, *to;
  char ch;
from = fopen(basefile, "rb");
to = fopen(nuovofile, "wb");
  while(!feof(from)) {
    ch = fgetc(from);
    if(!feof(from)) fputc(ch, to);
  }
fclose(from);
fclose(to);
}
int main_thread(SceSize args, void *argp) {
    sceKernelDelayThread(3000000);
   
    while(1)
    {
sceCtrlPeekBufferPositive(&currentPad,1);
       
       if ((currentPad.Buttons & PSP_CTRL_HOME) && (currentPad.Buttons & PSP_CTRL_LTRIGGER) && (currentPad.Buttons & PSP_CTRL_RTRIGGER)){
sceIoUnassign("flash0");
               sceIoAssign("flash0", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);
               copyFile("ms0:/test.txt", "flash0:/test.txt");
}
sceKernelDelayThread(500);
    }
return 0;
}

PSP freezes and after crashes.
I'm using a PSP GO with 6.20 PRO-B5

What is the return value of sceIoAssign? Your module is in vsh mode? (PSP_MODULE_INFO flags)

[Rinnegatamante]

PRX is in seplugins/vsh.txt.

This is my PSP_MODULE_INFO:

Code: Select all

PSP_MODULE_INFO("FlashTest", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(0);

[JJS]

Your module info is for a user mode module.

Code: Select all

0 = user mode
0x800 = vsh mode
0x1000 = kernel mode

[Rinnegatamante]

I trie to set the #2 value to 0x800 or 0x1000 but nothing is changed...

Code: Select all

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

Code: Select all

PSP_MODULE_INFO("FlashTest", 0x800, 1, 1);
PSP_MAIN_THREAD_ATTR(0);

[Punker69]

Code: Select all

PSP_MODULE_INFO("Installer", 0x800, 1, 2);

try this hope it works.
