Sorry for the unclear title but i couldn't think of something better.

I am trying to create a load from MS function but it seems to crash here:

Code:

         unsigned char count=0;
         unsigned char cursor=0;
         SceCtrlData pad;
         msg.ShowMessage("testpoint -1",0);
         bool go=1;
         while(go)
         {
            GraphicsObject::endFrame();
            GraphicsObject::startFrame();

            pspDebugScreenSetXY(0,0);
            pspDebugScreenPrintf("Files:\n");
            count=0;
            for(std::vector<SceIoDirent>::size_type i=0;i<filelist.size() && count <= 32;i++)
            {
               if(i==cursor)
                  pspDebugScreenPrintf("->%s\n",filelist[i].d_name);
               else
                  pspDebugScreenPrintf("  %s\n",filelist[i].d_name);
               count++;
            }
            if(cursor>count)
               cursor=count-2;

            sceCtrlReadBufferPositive(&pad,1);
            if(pad.Buttons & PSP_CTRL_UP && cursor>0)
               cursor--;
            if(pad.Buttons & PSP_CTRL_DOWN && cursor<32)
               cursor++;

            if(pad.Buttons & PSP_CTRL_CROSS){
               msg.ShowMessage("testpoint 0",0);
               go=0;
            }
         }
         msg.ShowMessage("testpoint 1",0);

I see the "testpoint -1" message. i can use the Up and DOWN button. But when i press CROSS it does nothing anymore. I don't see a crash report in PSPLink but i don't see the next message. Also without the message it stops responding.

I'm looking for some hour to this problem but i can't find a problem.

Can someone find the cause of that rpoblem?

From what I can see, once you press cross, you exit the while(go) loop and never render another frame... unless there is some code below that you haven't posted.

Well....
It's just a small part of a function. I see the first message "testpoint -1" but after i press CROSS it does nothing anymore.

This is the whole function:
Code:
void CellManager::loadFile()
{
   EasyMessage msg;
   SceUID dir;
   dir = sceIoDopen(".");
   if(dir)
   {
      std::vector<SceIoDirent> filelist;
      SceIoDirent entry;

      while(sceIoDread(dir,&entry))
      {
         if(strcmp(entry.d_name,"EBOOT.PBP")==0 || strcmp(entry.d_name,".")==0 || strcmp(entry.d_name,"..")==0)
         {            
         }
         else
         {
            filelist.push_back(entry);
         }
      }
      sceIoDclose(dir);
      if(filelist.size()>0)
      {
         unsigned char count=0;
         unsigned char cursor=0;
         SceCtrlData pad;
         msg.ShowMessage("testpoint -1",0);
         bool go=1;
         while(go)
         {
            GraphicsObject::endFrame();
            GraphicsObject::startFrame();

            pspDebugScreenSetXY(0,0);
            pspDebugScreenPrintf("Files:\n");
            count=0;
            for(std::vector<SceIoDirent>::size_type i=0;i<filelist.size() && count <= 32;i++)
            {
               if(i==cursor)
                  pspDebugScreenPrintf("->%s\n",filelist[i].d_name);
               else
                  pspDebugScreenPrintf("  %s\n",filelist[i].d_name);
               count++;
            }
            if(cursor>count)
               cursor=count-2;

            sceCtrlReadBufferPositive(&pad,1);
            if(pad.Buttons & PSP_CTRL_UP && cursor>0)
               cursor--;
            if(pad.Buttons & PSP_CTRL_DOWN && cursor<32)
               cursor++;

            if(pad.Buttons & PSP_CTRL_CROSS){
               msg.ShowMessage("testpoint 0",0);
               go=0;
            }
         }
         msg.ShowMessage("testpoint 1",0);
         SceUID fd = sceIoOpen(filelist[cursor].d_name,PSP_O_RDONLY,0777);
         if(fd)
         {
            unsigned char tSize[2];
            sceIoRead(fd,tSize,2);
            msg.ShowMessage("testpoint 2",0);
            if(tSize[0]>=20 && tSize[0]<=240 && tSize[1]>=20 && tSize[1]<=136)
            {
               msg.ShowMessage("testpoint 3",0);
               char tGrid[tSize[0]*tSize[1]];
               int tBytes=sceIoRead(fd,tGrid,tSize[0]*tSize[1]);
               if(tBytes==tSize[0]*tSize[1])
               {
                  initalise(tSize[0],tSize[1]);
                  clear();
                  for(int x=0;x<mWidth;x++)
                  {
                     for(int y=0;y<mHeight;y++)
                     {
                        if(tGrid[y*mWidth+x]=='1')
                           setAlive(x,y);
                        else
                           setDeath(x,y);
                     }
                  }
                  msg.ShowMessage("testpoint 4",0);
               }
               else
               {
                  msg.ShowMessage("File corrupted",0);
               }
            }
            else
            {
               msg.ShowMessage("File corrupted",0);
            }
            sceIoClose(fd);
         }
         else
         {
            msg.ShowMessage("Error opening file",0);
         }
      }
      else
      {
         msg.ShowMessage("No files found",0);
      }
   }
   else
   {
      msg.ShowMessage("Error while searching for files.",0);
   }
}

This looks suspicious:

Quote:

GraphicsObject::endFrame();
GraphicsObject::startFrame();


If you press X and you break out of the loop, it looks like there is still a pending startFrame() that might clash with the message drawing function? Just a guess.

It's just a sub-drawloop

I previous frame is started so i end that one at the beginning of the loop and start a new one.
When the loops ends the the rendering should continiue with the new frame.

I'd put a
Code:
GraphicsObject::endFrame();
GraphicsObject::startFrame();

after every
Code:
msg.ShowMessage();

At least then you know more about where you're getting up to. Failing that, are you running through psplink? Does it show the details of the crash?

PSPLink doesn't show a crashlog

I will try to initalise the GU again after the loop
