If enabled, 1/8 of the PSRAM total size will be reserved for error-correcting code. config SPIRAM_ALLOW_STACK_EXTERNAL_MEMORY bool "Allow external memory as an argument to xTaskCreateStatic" default y help Accessing memory in PSRAM has certain restrictions, so task stacks allocated by xTaskCreate are by default allocated from internal RAM. This option allows for passing memory allocated from PSRAM to be passed to xTaskCreateStatic. This should only be used for tasks where the stack is never accessed while the L2Cache is disabled, e.g. during SPI Flash operations source "$IDF_PATH/components/esp_psram/Kconfig.spiram.common" # insert non-chip-specific items here endmenu
