Function Documentation

char * get_reset_state_file ( )

Get pointer to reset state file.

int is_reset_state_file ( )

Check for reset state file.

void set_reset_magic ( uint32_t value )

Set reset constant.

Use this to force required 'after RESET' behavior before sys_reset() is used.

void set_reset_state_file ( const char * str )

Set reset state file to given string.

Parameters

str	String to set

Length of str should be less then RESET_STATE_FILE_SIZE and longer then zero, otherwise the reset state file is just unset (is_reset_state_file() returns 0).
