Dnxp_lpc54xxx.dtsi60 * SRAM0-SRAM3 will be contiguous memory when present.
62 * The board level or application level device tree can override the memory sizes
63 * to allocate memory to the different cores of the dual-core platforms.

DREADME.rst4 Allocate memory from SPIRAM.
9 This sample shows how to allocate memory from SPIRAM by using
11 memory was correctly allocated then frees it by calling :c:func:`shared_multi_heap_free`.
12 It also allocates memory from internal memory and checks if the address range is correct.
