Table 1 Macros for configuring the kernel heap memory
Macro
|
Description
|
|---|
LOSCFG_SYS_EXTERNAL_HEAP
|
Specifies whether the internal kernel heap memory or the user heap memory will be used. The default value is 0 and indicates that the internal heap memory whose size is 0x10000 will be used. If you want to use the external heap memory, set this macro to 1.
|
LOSCFG_SYS_HEAP_ADDR
|
Specifies the start address of the kernel heap memory.
|
LOSCFG_SYS_HEAP_SIZE
|
Specifies the size of the kernel heap memory, that is, size of the memory block specified by LOSCFG_SYS_HEAP_ADDR.
|
Ensure that the specified heap memory range is not used by other modules. Otherwise, functions of the heap memory will be damaged due to the heap memory corruption.
