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.

this function NEVER returns!
[in]crash_codea unique code for identifying the crash reason
[in]messagea human readable reason for the crash
this function never returns

◆ 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.
