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.

If enabled, firmware in flash including instructions and data will be moved into PSRAM on startup,
|
|
firmware code will execute directly from PSRAM.
|
|
|
|
With this option enabled, code that requires execution during an MSPI1 Flash operation
|
|
does not have to be placed in IRAM. Therefore codes that need to be executing during Flash
|
|
operations can continue working normally.
|
|
|
|
This feature is useful for high throughput peripheral involved applications to improve
|
|
the performance during MSPI1 flash operations.
