The 0xx800102FF task error is generated when the controller detects that the free memory chain of the heap is corrupted.

The heap is managed and used by the operating system to allocate memory for display objects and internal operating system needs.

The operating system had bugs in the code that created and deleted OS objects like tasks, counters, mail boxes, ring buffers, semaphores and resources. These OS calls all use heap memory and did not have all of the correct protection mechanisms in place to protect critical sections of the heap manager code.

Once the objects were created, protections were in place to protect these objects when they needed to make use of additional heap memory.

This problem exhibited itself during powerup when most OS objects are created but it could happen at any time. It also happened very repeatable on a Continuous Press Controller. However it only happened due to the happenstance of the timing involved in how the controller power cycles after a memory clear. It could have happened on any controller.
