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. Cannot be used together with ESP_COREDUMP_ENABLE_TO_FLASH. config SPIRAM_CLK_IO int default 30 config SPIRAM_CS_IO int default 26 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.
