i do this

Code: Select all

printf("\n Assigning Flash");
	if &#40;sceIoUnassign&#40;"flash0&#58;"&#41; < 0&#41;
                        printf&#40;"Cannot Un-Assign flash0&#58;"&#41;;
                        if &#40;sceIoAssign&#40;"flash0&#58;", "lflash0&#58;0,0", "flashfat0&#58;", IOASSIGN_RDWR, NULL, 0&#41; < 0&#41; &#123;
                                             printf&#40;"Error Assigning flash0 in write mode"&#41;; &#125;
       printf&#40;"Flash Assigned...\n\n"&#41;;
    printf&#40;"\n Flashing camera plugins "&#41;;
	copyFile&#40;"flash0&#58;/vsh/module/camera_plugin.prx", "ms0&#58;/camera_plugin.prx"&#41;;
	copyFile&#40;"flash0&#58;/vsh/resource/camera_plugin.rco", "ms0&#58;/camera_plugin.rco"&#41;;
	sceIoClose;
	printf&#40;"done"&#41;;

There is no access to flash0:/ from even a kernel module or user module. You unassign and reassign must be failing, but the code you've given just prints an error and continues without stopping. You can use one of these methods.

1) If you are just making an EBOOT application, then instead of making it user mode, make it VSH mode by giving 0x800 in PSP_MODULE_INFO("flash0w", 0x800, 1, 0);

Now you can unassign and reassign then freely read and write flash0:/.

2) If you are making a user mode prx or an EBOOT, then load DAX's iop.prx first. It comes with his LEDA application.

3) If you are making a kernel mode prx then #include <systemctrl.h> and add -lpspsystemctrl_kernel to your makefile libs. Then call this before assign, or open file, or read, or write.

int k1 = pspSdkSetK1(0);
int level = sctrlKernelSetUserLevel(8);

sceIoOpen(...);

sctrlKernelSetUserLevel(level);
pspSdkSetK1(k1);

Try making it usermode with iop.prx. Though I know that you CAN assign/unassign from a VSH mode eboot.

dont worry about the assigning problem, turned out that i was giving my psp to many kernal commands, i think....
im still trying to get that camera_plugin.rco though, still no hope
also
int k1 = pspSdkSetK1(0);
int level = sctrlKernelSetUserLevel(8);

sceIoOpen(...);

sctrlKernelSetUserLevel(level);
pspSdkSetK1(k1);
where eactly does this go, before i assign thew flash?
and sceIoOpen(...); <--is that the part where i flash the files or do i open iop.prx?
EDIT- solved, thank you very much for your help

okay when i use this before assigning

int k1 = pspSdkSetK1(0);
int level = sctrlKernelSetUserLevel(8);

sceIoOpen("flash0:/vsh/camera_plugin.rco", PSP_O_RDONLY, 0777);

sctrlKernelSetUserLevel(level);
pspSdkSetK1(k1);

it wont let me un assign flash

so can someone tell me how to do it, like ive tried everything i can think off
this is it currently


int k1 = pspSdkSetK1(0);
int level = sctrlKernelSetUserLevel(8);

sceIoOpen("flash0:/vsh/camera_plugin.rco", PSP_O_RDONLY, 0777);

sctrlKernelSetUserLevel(level);
pspSdkSetK1(k1);

pspSdkLoadStartModule("iop.prx", PSP_MEMORY_PARTITION_KERNEL);
p2c(" Assigning flash0....\n ");
if (sceIoUnassign("flash0:") < 0)
errorExit("Cannot Un-Assign flash0:");
if (sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0) < 0) {
errorExit("Error Assigning flash0 in write mode"); }
p2c(" Flash Assigned\n");
copyFile("flash0:/vsh/module/camera_plugin.prx", "ms0:/camera_plugin.prx");
copyFile("flash0:/vsh/resource/camera_plugin.rco", "ms0:/camera_plugin.rco");

but yet it only copies the prx

its a eboot it vsh mode (0x800)

Theres no need for VSH mode 0x800 if you are using iop.prx, make it user mode 0x0

First of all how can you call sctrlKernelSetUserLevel from a user mode prx?? I'm not at my dev PC but I'm pretty sure its a kernel only export.

If you're in kernel mode then iop.prx won't work.

Thats probably because of the permissions of the files. Test M33 or DC installed firmware sets all permissions on the files to 0777 which is full access.

For every file you handle=sceIoOpen, you should have a matching call to sceIoClose(handle). I'm not saying it'll fix your problem, but there are a limited number of file handles available (32?) and once they are all gone you won't be able to open any more files ever.
