CONFIG_SYS_HEAP_ALWAYS_BIG_MODE¶
Always use the heap big chunks mode
Type: bool
Help¶
The sys_heap allocator by default returns pointers to blocks which are guaranteed to be aligned to the pointer size. By enabling the “big chunks” mode, the returned blocks are guaranteed to be 8 byte aligned, also on 32-bit platforms. If this option is enabled, the “big chunks” mode will always be used by sys_heap.
