I've try to load the module of the exported function with loadstartmodule and pspSdkLoadStartModule but I've still get error 0x80020149!
Here is the stub file created: ( Execute is my function )
| Code: |
.set noreorder
#include "pspstub.s"
STUB_START "RDLib",0x40090000,0x00030005
STUB_FUNC 0x7F3D307A,SetConfFile
STUB_FUNC 0xB64186D0,SetUmdFile
STUB_FUNC 0xE86CA36E,Execute
STUB_END
|
Export file:
| Code: |
# Define the exports for the prx
PSP_BEGIN_EXPORTS
# These four lines are mandatory (although you can add other functions like module_stop)
# syslib is a psynonym for the single mandatory export.
PSP_EXPORT_START(syslib, 0, 0x8000)
PSP_EXPORT_FUNC_HASH(module_start)
PSP_EXPORT_VAR_HASH(module_info)
PSP_EXPORT_END
PSP_EXPORT_START(RDLib, 0, 0x4001)
PSP_EXPORT_FUNC(SetConfFile)
PSP_EXPORT_FUNC(SetUmdFile)
PSP_EXPORT_FUNC(Execute)
PSP_EXPORT_END
PSP_END_EXPORTS
|
Here is the prx:
| Code: |
PSP_MODULE_INFO("KrnlMod", 0x1007, 1, 0);
PSP_HEAP_SIZE_KB(1024);
#define printf pspDebugScreenPrintf

}
int module_start(SceSize args, void *argp)
{

{
sceKernelStartThread(th, args, argp);
}
return 0;
}

Execute function:
| Code: |
void Execute(char* target)
{
SceUID mod = sceKernelLoadModuleMs2(target, 0, NULL);
if (mod >= 0)
{
mod = sceKernelStartModule(mod, 0, NULL, NULL, NULL);
if (mod < 0)

}
else
{
pspDebugScreenInit();
printf("\nError 0x%08X loading module.\n", mod);
sleep(3000000);
}
}
|
And here is the function in the main programm:
| Code: |
SceUID mod = pspSdkLoadStartModule("ms0:/krnlmod.prx", PSP_MEMORY_PARTITION_KERNEL);
if(mod<0)
{
if (mod == SCE_KERNEL_ERROR_EXCLUSIVE_LOAD)
{
// Ignore this error, it means the module loaded on reboot
}
else
{
pspDebugScreenInit();
printf("\n(krnlmod.prx)Errore 0x%08X loading module.\n", mod);
sleep(3000000);
}
}
Execute("ms0:/PSP/GAME/HOMEBREW/EBOOT.PBP");

the 3rd argument in:
sceKernelLoadModuleMs2
from your execute function cannot be NULL

?? This is the function and it says that the 3rd arg can be NULL! |

try this:
| Code: |
SceKernelLMOption option;
SceUID mpid = PSP_MEMORY_PARTITION_USER;
memset(&option, 0, sizeof(option));
option.size = sizeof(option);
option.mpidtext = mpid;
option.mpiddata = mpid;
option.position = 0;
option.access = 1;
|
and use &option instead of NULL

when loading the kernel prx I believe.
right? (as you are not checking anything when using the Execute function)
Edit:
this should be your Execute function:
| Code: |
SceUID modid;
int status;
char args[1024];
int len;
SceKernelLMOption option;
SceUID mpid = PSP_MEMORY_PARTITION_USER;
memset(&option, 0, sizeof(option));
option.size = sizeof(option);
option.mpidtext = mpid;
option.mpiddata = mpid;
option.position = 0;
option.access = 1;
uid = sceKernelLoadModuleMs2(Line[0], 0, &option);
if (uid < 0)
{
// error
}
else {
len = build_args(args, Line[0], 0, NULL);
modid = sceKernelStartModule(uid, len, (void *) args, &status, NULL);
if (modid < 0)
{
// error
}
else {
// success
}
}
|
Edit 2:
make sure you have a build_args function in your code.
Use this one(I got it from psplink's source code)
| Code: |
int build_args(char *args, const char *execfile, int argc, char **argv)
{
int loc = 0;
int i;
strcpy(args, execfile);
loc += strlen(execfile) + 1;
for(i = 0; i < argc; i++)
{
strcpy(&args[loc], argv[i]);
loc += strlen(argv[i]) + 1;
}
return loc;
}

The error is from the execute function, when try to load the eboot.pbp!
The prx is loaded perfectly, I'm using another solution for args, but the problem is when I try to load a Eboot with the Execute function! |

There is a sample in the sdk of the CF 4.01 released by dark alex called bootload
that correspond what you will do:
Launching iso,psx,homebrew from a program and at end of the iso,psx,homebrew
return to the launcher |

he already knows but he is trying to use loadmodule* functions which support 3.xx kernel.
the sample included in 4.0.1 m33-x is for 4.0.1 m33-x and only works on those versions

try what I posted:
| Code: |
int Execute(char *file)
{
SceUID modid;
int status;
char args[1024];
int len;
SceKernelLMOption option;
SceUID mpid = PSP_MEMORY_PARTITION_USER;
memset(&option, 0, sizeof(option));
option.size = sizeof(option);
option.mpidtext = mpid;
option.mpiddata = mpid;
option.position = 0;
option.access = 1;
uid = sceKernelLoadModuleMs2(file, 0, &option);
if (uid < 0)
{
// error
return uid;
}
else {
len = build_args(args, file, 0, NULL);
modid = sceKernelStartModule(uid, len, (void *) args, &status, NULL);
if (modid < 0)
{
// error
return modid;
}
else {
// success
}
} |

Still error 0x80020149... :(
Maybe I've do a error in the export file or else because the error means
that the operation is not permitted (ILLEGAL... ), so I've think that I've do a error... |

are you trying to launch a kernel homebrew? lol
that maybe your problem.
If the homebrew you are trying to load is kernel mode you may get that error :/

No, it's a normal user hb!
I've try to build my prog as a normal Eboot ( no BUILD_PRX) and when I call the execute function the PSP crash! :( |

Ok, I've tryed to edit the DAX sample and if I try to execute a file using the exported function I've error 0x80020149 ( I think it's because I cannot use the module mgr function in a exported funct ) and if I try to load with your Execute function the PSP crash before the error is completely printed!
( For example the last time that I've try to start it I've seen on the screen:
"Erro" and the PSP crash before I can see the error! Why??
EDIT:
Have you already found a solution for that I'm trying to do? |

there should be NO problem exporting a function with load module.
which Execute function are you using, mine or yours?

then use it like this:
int exec = Execute("path/here");
if (exec < 0) {
printf("0x%08X", exec); // prints error to the screen
sceKernelDelayTHread(100000*2); // waits 2 seconds
}

I know, that was to fix the "I can't see the error" problem lol.
Which firmware are you on?
Do you have 1.50 kernel enabled?

you know what you need to load your prx before using the Execute function right?
anyway
Do this instead:
create a pbp.
create a prx which has the execute function. (dont export it)
load the prx from the pbp. the prx loads the path from a file written by the pbp. the prx uses the path got from the file and uses it in the execute function.
Make sure you use the apihook lib from psplink (included in the sample by cpasjuste).
just hook sceKernelExitGame instead of loading dax's driver as it is just useful for 4.xx kernel

Yes, I know, if I didn't load the prx the function isn't executed without errors!
However, I'm using the DAx function for patch the exit game function and it works great!
Anyway why I have to load the path from file? Can't I pass it as a arg? I've already do it and it works fine! ( exep the load error ).
Thanks very much, I'll try your solution! |

yeh you can pass the path but in my case as I have to pass at least 3 arguments, it's easier than passing the arguments from the pbp to the prx
