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.
Cannot be used together with ESP_COREDUMP_ENABLE_TO_FLASH.

If enabled, instruction in flash will be copied into SPIRAM.
If SPIRAM_RODATA also enabled, you can run the instruction when erasing or programming the flash.
