flash USB connection

[Sleepy566]

How can I make the USB connect to the flash0 or flash1 instead of the ms0?

I have tried this:

Code: Select all

   sceIoUnassign("ms0:");
   sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);

but that doesn't seem to do anything... I know I'm missing something but I've completely forgotten what it is.

Who cares?

I do. I wanted to be able to access my flash drives through an eboot program so I could modify the files.

that is a function allowed in one of the recovery mode of one of the latter DAX firmwares I think

[harleyg]

Yeah it is, but he wants to copy it...

[Sleepy566]

not exactly copy it, but use it in a different program.

[glynnder]

so, copy it?

[codes02]

the only problem with that code is that on the assign the mention of the device needs to be "ms0:"

Code: Select all

sceIoAssign("ms0:", "lflash0:0,0", "fatms0:", IOASSIGN_RDWR, NULL, 0);

before you were just reassigning flash0, probably returning an error code because it was already mounted. I also put in a change in the map for the block device, which may also be nessicary (or not).

Now you just have to start up the usb mass storage drivers

ooohhhh... so shouldn't this work? It didn't work when I tried to compile it in the complete program. Well, it compiled but when I ran it on the PSP it connected to the ms0 instead of the flash0. Should I remove sceIoUnassign() or the "fatms0:" part? (I have a gut feeling it's one of those two)

Code: Select all

void start_usbf0()
{
	sceIoUnassign("ms0:");
	sceIoAssign("ms0:", "lflash0:0,0", "fatms0:", IOASSIGN_RDWR, NULL, 0);

	pspSdkLoadStartModule("flash0:/kd/semawm.prx", PSP_MEMORY_PARTITION_KERNEL);
	pspSdkLoadStartModule("flash0:/kd/usbstor.prx", PSP_MEMORY_PARTITION_KERNEL);
	pspSdkLoadStartModule("flash0:/kd/usbstormgr.prx", PSP_MEMORY_PARTITION_KERNEL);
	pspSdkLoadStartModule("flash0:/kd/usbstorms.prx", PSP_MEMORY_PARTITION_KERNEL);
	pspSdkLoadStartModule("flash0:/kd/usbstorboot.prx", PSP_MEMORY_PARTITION_KERNEL);

	sceUsbStart(PSP_USBBUS_DRIVERNAME, 0, 0);
	sceUsbStart(PSP_USBSTOR_DRIVERNAME, 0, 0);
	sceUsbstorBootSetCapacity(0x800000);

	sceUsbActivate(0x1c8);

	usbStarted = 1;
	printf("\nUSB activated\n");
}

how do u activate it with buttons?

LOL. Looks like a newcomer is trying to take my idea.

}

if it was like this , it shouldnt took 2years before somebody founds out xD
wasnt USB SSS open source?

[pspwill]

To assign flash0:/ to usb you need to create a new driver for it using the sceIoDrv functions. Theres an example of this in the mph fw launcher source.

[moonlight]

It is more complicated that simple assign/unassign.

You have to redirect the msstor driver functions to the lflash driver functions, and handle some msstor specific ioctl codes (0x02125008, 0x02125803) and devctl codes (0x02125801).

Thanks a bunch, I'll check it out asap!

[MSN]

were you able to connet the flash to usb?

[Sleepy566]

Not yet, the driver functions from MPHL's firmware launcher code are a bit confusing.

Don't worry, I'm still working it on it.
