Copy Files into Flash0

[Rinnegatamante]

Nothing is changed...

It's very strange... it freezes and crashes, file in flash0 isn't created...

P.S. I tried also:

Code: Select all

PSP_MODULE_INFO("EasyDualboot", 0x1000, 1, 2);

But nothing...

Can i post complete source codes in a RAR archive?

Here are my files:

Code: Select all

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

try this hope it works.

i said try this one. I Use this in my app called flashdumper

[Rinnegatamante]

I tried it with the source that i've posted but it doesn't work...

[m0skit0]

Just FYI, I would never try a homebrew that messes with flash0, specially on unhackables. You should not copy anything into flashes unless you have no other way.

[Rinnegatamante]

I must copy a file into flash0 for the good realization of the homebrew...

[Rinnegatamante]

I tried this:

Code: Select all

if (sceIoUnassign("flash0:") < 0){
config=fopen("ms0:/unassign.txt", "w");
char buffer[] = { 'U' };
fwrite(buffer,1,sizeof(buffer),config);
fclose(config);
}
if (sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0) < 0){
config=fopen("ms0:/assign.txt", "w");
char buffer[] = { 'U' };
fwrite(buffer,1,sizeof(buffer),config);
fclose(config);
}

And when i charge my prx, i'll get error from unassign and assign function (and relative files are been created with U character). :S

[Rinnegatamante]

I tried to load iop.prx but nothing change but if i use iop.prx in an EBOOT.PBP, it flashes normally...why?

[m0skit0]

Your PRX must be kernel mode to do such thing.

[Rinnegatamante]

Code: Select all

PSP_MODULE_INFO("Test Flash", 0x800, 1, 2);

This is my MODULE_INFO (i tried also 0x1000).

Code: Select all

PSP_MODULE_INFO("homebrew", 0x800, 1, 0);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_VSH);

Code: Select all

BUILD_PRX = 1

+ reassign flash0 in write mode. It's for PBP.

This code works in my 5.00 m33 plugins add-on for k1.50.
