Public Functions Documentation

function syn_fault_capture

Capture a CPU fault register state.

void syn_fault_capture (
    const SYN_FaultContext * ctx
) 

Saves register dump to uninitialized RAM and sets the signature. Safe to call from a hard fault handler (no heap, no locks).

Parameters:

• ctx Pointer to the register context to save (NULL is ignored).

function syn_fault_check_and_log

Checks if a crash occurred in a previous boot, logs it, and clears the signature.

bool syn_fault_check_and_log (
    SYN_ErrLog * errlog
)

• errlog Pointer to the active error log.

Returns:

true if a fault was checked, logged, and cleared.
