CONFIG_MBEDTLS_HEAP_SIZE
¶
Heap size for mbed TLS
Heap size for mbed TLS
Heap size for mbed TLS
Type: int
Help¶
The mbedtls routines will use this heap if enabled.
See ext/lib/crypto/mbedtls/include/mbedtls/config.h and
MBEDTLS_MEMORY_BUFFER_ALLOC_C option for details. That option is not
enabled by default.
Default value for the heap size is not set as it depends on the
application. For streaming communication with arbitrary (HTTPS)
servers on the Internet, 32KB + overheads (up to another 20KB) may
be needed. For some dedicated and specific usage of mbedtls API, the
1000 bytes might be ok.
Help¶
Heap size for mbed TLS in bytes.
For streaming communication with arbitrary (HTTPS) servers on the
Internet, 32KB + overheads (up to another 20KB) may be needed.
Ensure to adjust the heap size according to the need of the
application.
