Assign flash0 in read/write mode [Solved]

Magniot · Post by **Magniot** » Tue Dec 30, 2008 10:03 pm

Hi, i'm new on this forum. I'm french.

I've got one problem: i'm trying to create an homebrew to flash files in flash0 but i don't arrive to create directories in flash0.

Code: Select all

sceIoUnassign&#40;"flash0"&#41;;
sceIoAssign&#40;"flash0", "lflash0&#58;0,0", "flashfat0&#58;", IOASSIGN_RDWR, NULL, 0&#41;;
sceIoMkdir&#40;"flash0&#58;/test", 0777&#41;;

Is this code correct? Because nothing is created in flash0.
Thanks

You was almost correct you are missing a ":"

Here is the function I use it has error checking but I don't use it, lol

Code: Select all

/**
  * Reassign flash0/flash1 to enable read and write access.
  *
  * @param - n/a
  *
  * @returns - n/a
  **********************************************************************************************************/
	void Reassign&#40;&#41; &#123;
		
		
		if &#40;sceIoUnassign&#40;"flash0&#58;"&#41; < 0&#41; &#123;
			// Unassign failed
		&#125;
		
		if &#40;sceIoAssign&#40;"flash0&#58;", "lflash0&#58;0,0", "flashfat0&#58;", IOASSIGN_RDWR, NULL, 0&#41; < 0&#41; &#123;
			// Assign failed
		&#125;
		
		
		
		if &#40;sceIoUnassign&#40;"flash1&#58;"&#41; < 0&#41; &#123;
			// Unassign failed
		&#125;
		
		if &#40;sceIoAssign&#40;"flash1&#58;", "lflash0&#58;0,1", "flashfat1&#58;", IOASSIGN_RDWR, NULL, 0&#41; < 0&#41; &#123;
			// Assign failed
		&#125;
		
		
		
	&#125;

Thanks. now i've got another problem lol

Code: Select all

void Reassign&#40;&#41; &#123;
      
      
      if &#40;sceIoUnassign&#40;"flash0&#58;"&#41; < 0&#41; &#123;
         // Unassign failed
      &#125;
      
      if &#40;sceIoAssign&#40;"flash0&#58;", "lflash0&#58;0,0", "flashfat0&#58;", IOASSIGN_RDWR, NULL, 0&#41; < 0&#41; &#123;
         // Assign failed
      &#125;
      
      
      
      if &#40;sceIoUnassign&#40;"flash1&#58;"&#41; < 0&#41; &#123;
         // Unassign failed
      &#125;
      
      if &#40;sceIoAssign&#40;"flash1&#58;", "lflash0&#58;0,1", "flashfat1&#58;", IOASSIGN_RDWR, NULL, 0&#41; < 0&#41; &#123;
         // Assign failed
      &#125;
      
      
      
   &#125;

and in int main after my part of code there is:

Code: Select all

Reassign&#40;&#41;;
sceIoMkdir&#40;"flash0&#58;/test", 0777&#41;;

And it's the same, nothing was created when i launched my eboot on my psp. my text is on the screen but when i toogle usb flash0 the directorie isn't here.

Try...

sceIoMkdir("flash0:/test/", 0777);

and it doesn't work too. I've already tested it and i have tested it again.

If you've got a flasher source code made by you or someone else please upload it or post it to have an example. Thanks for all and sorry :)

I have not messed with flash0 since 3.80 / 3.90

I remember having problems with certain modes and ended up using 0x800 in my module info,

Code: Select all

PSP_MODULE_INFO&#40;"Write2Flash380", 0x800, 1, 1&#41;;
PSP_MAIN_THREAD_ATTR&#40;0&#41;;
PSP_HEAP_SIZE_MAX&#40;&#41;;

It works!!!!! Thanks!
and to create dirs:

Code: Select all

sceIoMkdir&#40;"flash0&#58;/test", 0777&#41;;

without "/" after name directorie.

Thanks again.
