/* Initialize heap allocator. WARNING: This *needs* to happen *after* the app cpu has booted.
|
|
|
|
If the heap allocator is initialized first, it will put free memory linked list items into
|
|
|
|
memory also used by the ROM. Starting the app cpu will let its ROM initialize that memory,
|
|
|
|
corrupting those linked lists. Initializing the allocator *after* the app cpu has booted
|
|
|
|
works around this problem.
|
|
|
|
With SPI RAM enabled, there's a second reason: half of the SPI RAM will be managed by the
|
|
|
|
app CPU, and when that is not up yet, the memory will be inaccessible and heap_caps_init may
|
|
|
|
fail initializing it properly. */
