Detailed Description

ARM7TDMI GCC context switch frame layout.

AVR32 GCC context switch frame layout.

ICC AVR context switch frame layout.

AVR GCC context switch frame layout.

This is the layout of the stack after a thread's context has been switched-out. The stack pointer is stored in the thread info and points to this structure.

This is the layout of the stack after a thread's context has been switched-out.
