|
|
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
