 Posted: Wed Dec 06, 2006 12:34 am Post subject: [RESOLVED] PRX Causing 2.71 SE-C Homebrew to Crash |
 |
|
I've got a problem with PRXs on 2.71 SE-C and wondered if anyone knew of a way around it...?
I have tried with numerious PRXs and it seems to happen for all of them...
If I enable my PRX (or any PRX) in the VSH via the Recovery menu they work fine in the XMB but if I try to launch any homebrew (DevHook for example) then the system hangs at the white PSP animation that you get when things start...
I even created a PRX that does nothing except loop to check it wasn't something code wise that was causing the problem and get the same problem with that (see code below),
| Code: | #include <pspctrl.h>
#include <pspkernel.h>
#include <stdio.h>
PSP_MODULE_INFO("PRX Test", 0x1000, 1, 0);
PSP_MAIN_THREAD_ATTR(0);
int MainThread (SceSize args, void *argp) {
while (1) {
sceKernelDelayThread(10000);
}
return 0;
}
int module_start(SceSize args, void *argp) {
SceUID thid;
thid = sceKernelCreateThread("PRX_Test", MainThread, 0x18, 0x1000, 0, NULL);
if (thid >= 0) sceKernelStartThread(thid, args, argp);
return 0;
}
int module_stop(void) {
return 0;
} |

I finally found the solution so thought I'd post for others who may have the same issue...
You need to add the following function that checks for SceKernelLoadExecThread and safely terminates the module,
| Code: | void CheckCleanExit(void) {
SceUID thids[50];
int thid_count = 0;
int i;
SceUID fd;
SceUID memid;
SceKernelThreadInfo thinfo;
//if sceKernelExitGame was called, exit before the system crashes
sceKernelGetThreadmanIdList(SCE_KERNEL_TMID_Thread,thids,50,&thid_count);
for(i=0;i<thid_count;i++)
{
memset(&thinfo,0,sizeof(SceKernelThreadInfo));
thinfo.size = sizeof(SceKernelThreadInfo);
sceKernelReferThreadStatus(thids[i],&thinfo);
if(strcmp(&thinfo.name[0],"SceKernelLoadExecThread")==0)
{
sceKernelSelfStopUnloadModule(0, 0, NULL);
}
}
} |
Now simple call this function at the top of the main thread's while loop and the module will now not prevent loading homebrew when enabled in the XMB on 2.71 SE-C...
| Code: | #include <pspctrl.h>
#include <pspkernel.h>
#include <stdio.h>
PSP_MODULE_INFO("PRX Test", 0x1000, 1, 0);
PSP_MAIN_THREAD_ATTR(0);
int MainThread (SceSize args, void *argp) {
while (1) {
CheckCleanExit();
sceKernelDelayThread(10000);
}
return 0;
}
int module_start(SceSize args, void *argp) {
SceUID thid;
thid = sceKernelCreateThread("PRX_Test", MainThread, 0x18, 0x1000, 0, NULL);
if (thid >= 0) sceKernelStartThread(thid, args, argp);
return 0;
}
int module_stop(void) {
return 0;

| I've discovered this method stops my module working when the Homebrew is loaded (works fine for games)... Anybody got any ideas how to get around this...? |
