Macro Definition Documentation

◆ CONFIG_CORE_REBOOT_ON_PANIC

#define CONFIG_CORE_REBOOT_ON_PANIC (0)

Automatically reboot the system on panic()

By default this is on when DEVELHELP is disabled.

Definition at line 38 of file panic.h.

Enumeration Type Documentation

◆ core_panic_t

enum core_panic_t

Definition of available panic modes.

Enumerator
PANIC_MEM_MANAGE	memory management fault
PANIC_SSP	stack smashing protector failure
PANIC_STACK_OVERFLOW	stack overflow detected

Definition at line 47 of file panic.h.

Function Documentation

◆ core_panic()

NORETURN void core_panic	(	core_panic_t	crash_code,
		const char *	message )

Handle an unrecoverable error by halting or rebooting the system.

A numeric code indicating the failure reason can be given as the crash_code parameter.

Detailing the failure is possible using the message parameter. This function should serve a similar purpose as the panic() function of Unix/Linux kernels.

If the DEVELHELP macro is defined, the system will be halted; the system will be rebooted otherwise.

Warning: this function NEVER returns!

Parameters

[in]	crash_code	a unique code for identifying the crash reason
[in]	message	a human readable reason for the crash

◆ panic_arch()

void panic_arch ( void )

architecture dependent handling of a panic case

This function gives the CPU the possibility to execute architecture dependent code in case of a severe error.
