help
|
|
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.

help
|
|
- Quad PSRAM 120 MHz is stable.
|
|
|
|
- Octal PSRAM 120 MHz is an experimental feature, it works when
|
|
the temperature is stable.
|
|
|
|
Risks:
|
|
If your chip powers on at a certain temperature, then after the temperature
|
|
increases or decreases by approximately 20 Celsius degrees (depending on the
|
|
chip), the accesses to / from PSRAM will crash randomly.
