Function Documentation

on_hard_fault()

void sbl::fault::on_hard_fault ( const uint32_t *  frame )

inline

Format and output the Cortex-M exception stack frame.

The Cortex-M exception entry pushes these registers onto the active stack (MSP or PSP): [0] R0 [1] R1 [2] R2 [3] R3 [4] R12 [5] LR [6] PC [7] xPSR

The faulting instruction address is frame[6] (stacked PC). frame[5] (stacked LR) shows where the faulting function would have returned to.

Parameters

frame

Pointer to the exception stack frame
