Why my psp show the Sony error screen when I try this code :

what type of error does PSP show?

what type of error does PSP show?

PSP shows the following error when I connect again to the USB Mode:

Code: Select all

An internal error has ocurred (80243101)

You are not calling original functions, wo aht you would expect?
Your GetState and Stop functions should call original functions for this to work.

[Mashphealh]

Yes, you don't call original function. Try using this code :

int USB_GetState(void)
{
int k1 = pspSdkSetK1(0);

sceDisplayGetBrightness(&curBrightness, 0);
sceDisplaySetBrightness(0, 0);


pspSdkSetK1(k1);

return sceUsbGetState();


}

int USB_Stop(const char* driverName, int size, void *args)
{
int k1 = pspSdkSetK1(0);

sceDisplaySetBrightness(curBrightness, 0);



pspSdkSetK1(k1);

return sceUsbStop(driverName, size, args);


}

M33's vshctrl patches sceUsbStop also, so I don't know if now usbdevice works for you.

The PSP crashes with the original functions, with the same Mashphealt's code, why moonlight?

[moonlight]

The usb stop function should be like this. The original function must be executed between the k1 stuff. This doesn't matter in the GetState one.

int USB_Stop(const char* driverName, int size, void *args)
{
int k1 = pspSdkSetK1(0);
sceDisplaySetBrightness(curBrightness, 0);
int ret = sceUsbStop(driverName, size, args)
pspSdkSetK1(k1);
return ret;
}

{

sceDisplaySetBrightness(curBrightness, 0);
int ret = sceUsbStop(driverName, size, args)
pspSdkSetK1(k1);
return ret;
}

It crashes again, why?

int USB_GetState(void)
{
int k1 = pspSdkSetK1(0);

sceDisplayGetBrightness(&curBrightness, 0);
sceDisplaySetBrightness(0, 0);


pspSdkSetK1(k1);

return 0;


}

int USB_Stop(const char* driverName, int size, void *args)
{
int k1 = pspSdkSetK1(0);
sceDisplaySetBrightness(curBrightness, 0);
int ret = sceUsbStop(driverName, size, args);
pspSdkSetK1(k1);
return ret;
}

maybe, if you want make a prx you haven't to give 0x1000 at PSP_MODULE_INFO, maybe...

[moonlight]

Do a test commenting the calls to the display functions, to see if it crashes too or not.

Prx still crashes, any idea?

[ne0h]

A suggestion, When you ask for something post the entire code, the makefile and give more infos, I can't see your actual code...
Anyway if I'm right you want to hook the usb load?
To do this use the m33 module handler, is better then hook some functions I think...
Sorry for my english...
