config SPIRAM

This enables support for an external SPI RAM chip, connected in parallel with the
main SPI flash chip.

config SPIRAM_ALLOW_STACK_EXTERNAL_MEMORY
bool "Allow external memory as an argument to xTaskCreateStatic"
default y
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.

config SPIRAM_FETCH_INSTRUCTIONS
bool "Move Instructions in Flash to PSRAM"
default n
help
If enabled, instructions in flash will be moved into PSRAM on startup.
If SPIRAM_RODATA is also enabled, code that requires execution during an SPI1 Flash operation
can forgo being placed in IRAM, thus optimizing RAM usage (see External RAM documentation
for more details).
config SPIRAM_RODATA
bool "Move Read-Only Data in Flash to PSRAM"
default n
help
If enabled, rodata in flash will be moved into PSRAM on startup.
If SPIRAM_FETCH_INSTRUCTIONS is also enabled, code that requires execution during an SPI1 Flash operation
can forgo being placed in IRAM, thus optimizing RAM usage (see External RAM documentation
for more details).

config SPIRAM_SPEED_120M
depends on SPIRAM_MODE_QUAD || IDF_EXPERIMENTAL_FEATURES
bool "120MHz clock speed"
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.

Enable MSPI Error-Correcting Code function when accessing SPIRAM.
If enabled, 1/16 of the SPI RAM total size will be reserved for error-correcting code.
