pub static mut APP_HARD_FAULT: UnsafeCell<usize>Expand description
This is called in the hard fault handler. When set to 1 this means the hard
fault handler was called. Marked pub because it is used in the cortex-m*
specific handler.
n.b. If the kernel hard faults, it immediately panic’s. This flag is only for handling application hard faults.
Because this is a global static mut variable, we can only access it from
inline assembly.
