CONFIG_CORTEX_M_NULL_POINTER_EXCEPTION_PAGE_SIZE¶
Size of paged unmapped to implement null pointer detection
Type: hex
Help¶
Size of the page reserved for detecting null pointer
dereferencing. Must be a power of two. A large value
offers enhanced detection performance to the cost of
wasting a large flash area that code may not use.
Direct dependencies¶
CORTEX_M_NULL_POINTER_EXCEPTION
&& CPU_CORTEX_M
&& ARM
(Includes any dependencies from ifs and menus.)
Default¶
0x400
