- help
- Accessing memory in PSRAM has certain restrictions, so task stacks allocated by xTaskCreate
- are by default allocated from internal RAM.
- This option allows for passing memory allocated from PSRAM to be passed to xTaskCreateStatic.
- This should only be used for tasks where the stack is never accessed while the L2Cache is
- disabled, e.g. during SPI Flash operations
