Accessing memory in SPIRAM has certain restrictions, so task stacks allocated by xTaskCreate
|
||
|
|
are by default allocated from internal RAM.
|
||
|
|
|
||
|
|
This option allows for passing memory allocated from SPIRAM to be passed to xTaskCreateStatic.
|
||
|
|
This should only be used for tasks where the stack is never accessed while the cache is disabled.
