A C++ game I'm working works fine on the simulator, but crashes on device. Here's the log:
build:-828eb1f2 r0:00000000 r1:00000000 r2:00030c97 r3: 00000000 r12:006d3000 lr:0803022b pc:0802ff4a psr: 61000000 cfsr:00000082 hfsr:00000000 mmfar:00000000 bfar: 00000000 rcccsr:00000000 heap allocated: 1080896 Lua totalbytes=113800 GCdebt=-56640 GCestimate=56960 stacksize=42
System version is 1.11.0.
Clearly, I haven't provided much additional detail. I am not yet sure what line of code is causing the crash. However, since the program counter is in kernel-space, I assume it's crashing in some playdate API function somewhere.
It would be very helpful, in situations like this, to be able to print a special message on crash to help debug the cause of the crash. Even if there were just a special register that we could write to which, on crash, would be printed as a hex value, it would be tremendously helpful. Print statements aren't reliable enough to determine the location of the crash, as the tx buffer might not be flushed by the time the system crashes.
