Beta 17: Quick backdrops with Motif on 2nd gen

[AndyH]

Please see attached file. On my 4th gen itouch this runs fine. On my wife's 2nd gen itouch the app crashes.

The quick backdrop is 256x256 in size, but the motif image is 64x64 pixels in size.

I've discovered this in my game. I added a quick backdrop with the motif and the music starts playing with a black screen for about 3-4 seconds and then the music stops and nothing else happens.

I thought it was a memory issue on a 2nd Gen device but as you can see in the cut down example there's nothing much in there. In my game I changed the quick backdrop into a normal background object. It's now at 256x256 pixels for the image data (instead of the 64x64 motif) and this is working on both the 2nd and 4th gen devices.

So looks like some sort of problem for motif quick backdrops on 2nd gen devices.

I've tried running it on a 3GS iPod Touch with the ES1 renderer the 2nd gen devices uses but it worked fine.

Can you by any chance give me a stacktrace/crashlog of the crash?

[AndyH]

Sure, can you let me know how to do that please

[AndyH]

Is this what you need?

When I view the debugger window it mentions it has stopped on EXC_BAD_ACCESS.

If you can't find the info anywhere else:

I think there is a problem with XCode. My 2nd gen iPod refuses to upgrade to 4.3 (I have read on the net that these devices are stuck to 4.2). When I run any application on it, nothing happens, the loading screen stays displayed. I get a lot of system warnings and errors in the console.
This is bad news, as I wont be able to debug on such a device...

I think things are going fast with Apple and its release, and we should not spend efforts aim and devices before they themselves have the force.

I also believe that since the processor A4 efforts going forward.
