If enabled, instructions in flash will be moved into PSRAM on startup.
|
|
If SPIRAM_RODATA is also enabled, code that requires execution during an MSPI1 Flash operation
|
|
can forgo being placed in IRAM. Therefore codes that need to be executing during Flash
|
|
operation can continue working normally.
|
|
|
|
This feature is useful for high throughput peripheral involved applications to improve
|
|
the performance during MSPI1 flash operations. PSRAM access speed is faster than Flash access.
|
|
So the performance is better. (see External RAM documentation for more details).

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.

Temperature would influence the source clock frequency so that the timing tuning point set in start-up

might not be always proper when temperature varies in high range. This configuration would help checking

the temperature in real-time, and adjust timing point automatically when temperature change.
