CONFIG_ESP_HEAP_MEM_POOL_REGION_1_SIZE¶

Internal DRAM region 1 mempool size

Type: int

Help¶

ESP32 has two banks of size 192K and 128K which can be used
as DRAM, system heap allocates area from region 0.
This configuration can be used to add memory from region 1
to heap and can be allocated using k_malloc.
