Function teensy4_bsp::dtcm_heap_start

pub fn dtcm_heap_start() -> *mut u32

Returns the starting location for a DTCM “heap.”

The recommended heap is in OCRAM2, and available using heap_start(). But, you may choose to place the heap in DTCM. This function returns the starting address for that heap.

The DTCM heap is expected to grow up towards the stack, and has no statically-known maximum size. The pointer is guaranteed to be 4 byte aligned.
