# This is actually also handled in the ESP32 startup code, not only in FreeRTOS.
config FREERTOS_UNICORE
bool "Run FreeRTOS only on first core"
default n
help
This version of FreeRTOS normally takes control of all cores of
the CPU. Select this if you only want to start it on the first core.
This is needed when e.g. another process needs complete control
over the second core.
choice FREERTOS_CORETIMER
prompt "Xtensa timer to use as the FreeRTOS tick source"
default CONFIG_FREERTOS_CORETIMER_0
help
FreeRTOS needs a timer with an associated interrupt to use as
the main tick source to increase counters, run timers and do
pre-emptive multitasking with. There are multiple timers available
to do this, with different interrupt priorities. Check
config FREERTOS_CORETIMER_0
bool "Timer 0 (int 6, level 1)"
help
Select this to use timer 0
config FREERTOS_CORETIMER_1
bool "Timer 1 (int 15, level 3)"
help
Select this to use timer 1
config FREERTOS_CORETIMER_2
bool "Timer 2 (int 16, level 5)"
help
Select this to use timer 2
endchoice
config FREERTOS_HZ
int "Tick rate (Hz)"
range 1 1000
default 100
help
Select the tick rate at which FreeRTOS does pre-emptive context switching.
config FREERTOS_ASSERT_ON_UNTESTED_FUNCTION
bool "Halt when an SMP-untested function is called"
default y
help
Some functions in FreeRTOS have not been thoroughly tested yet when moving to
the SMP implementation of FreeRTOS. When this option is enabled, these fuctions
will throw an assert().
choice FREERTOS_CHECK_STACKOVERFLOW
prompt "Check for stack overflow"
default FREERTOS_CHECK_STACKOVERFLOW_QUICK
help
FreeRTOS can check for stack overflows in threads and trigger an user function
called vApplicationStackOverflowHook when this happens.
config FREERTOS_CHECK_STACKOVERFLOW_NONE
bool "No checking"
help
Do not check for stack overflows (configCHECK_FOR_STACK_OVERFLOW=0)
config FREERTOS_CHECK_STACKOVERFLOW_PTRVAL
bool "Check by stack pointer value"
help
Check for stack overflows on each context switch by checking if
the stack pointer is in a valid range. Quick but does not detect
stack overflows that happened between context switches
(configCHECK_FOR_STACK_OVERFLOW=1)
config FREERTOS_CHECK_STACKOVERFLOW_CANARY
bool "Check using canary bytes"
help
Places some magic bytes at the end of the stack area and on each
context switch, check if these bytes are still intact. More thorough
than just checking the pointer, but also slightly slower.
(configCHECK_FOR_STACK_OVERFLOW=2)
endchoice
config FREERTOS_THREAD_LOCAL_STORAGE_POINTERS
int "Amount of thread local storage pointers"
range 0 256 if !WIFI_ENABLED
range 1 256 if WIFI_ENABLED
default 1
help
FreeRTOS has the ability to store per-thread pointers in the task
control block. This controls the amount of pointers available;
0 turns off this functionality.
If using the WiFi stack, this value must be at least 1.
choice FREERTOS_ASSERT
prompt "FreeRTOS assertions"
default FREERTOS_ASSERT_FAIL_ABORT
help
Failed FreeRTOS configASSERT() assertions can be configured to
behave in different ways.
config FREERTOS_ASSERT_FAIL_ABORT
bool "abort() on failed assertions"
help
If a FreeRTOS configASSERT() fails, FreeRTOS will abort() and
halt execution. The panic handler can be configured to handle
the outcome of an abort() in different ways.
config FREERTOS_ASSERT_FAIL_PRINT_CONTINUE
bool "Print and continue failed assertions"
help
If a FreeRTOS assertion fails, print it out and continue.
config FREERTOS_ASSERT_DISABLE
bool "Disable FreeRTOS assertions"
help
FreeRTOS configASSERT() will not be compiled into the binary.
endchoice
config FREERTOS_BREAK_ON_SCHEDULER_START_JTAG
bool "Stop program on scheduler start when JTAG/OCD is detected"
depends on ESP32_DEBUG_OCDAWARE
default y
help
If JTAG/OCD is connected, stop execution when the scheduler is started and the first
task is executed.
menuconfig ENABLE_MEMORY_DEBUG
bool "Enable heap memory debug"
default n
help
Enable this option to show malloc heap block and memory crash detect
config FREERTOS_ISR_STACKSIZE
int "ISR stack size"
range 1536 32768
default 1536
help
The interrupt handlers have their own stack. The size of the stack can be defined here.
Each processor has its own stack, so the total size occupied will be twice this.
config FREERTOS_LEGACY_HOOKS
bool "Use FreeRTOS legacy hooks"
default n
help
FreeRTOS offers a number of hooks/callback functions that are called when a timer
tick happens, the idle thread runs etc. esp-idf replaces these by runtime registerable
hooks using the esp_register_freertos_xxx_hook system, but for legacy reasons the old
hooks can also still be enabled. Please enable this only if you have code that for some
reason can't be migrated to the esp_register_freertos_xxx_hook system.
if FREERTOS_LEGACY_HOOKS
config FREERTOS_LEGACY_IDLE_HOOK
bool "Enable legacy idle hook"
default n
help
If enabled, FreeRTOS will call a function called vApplicationIdleHook when the idle thread
on a CPU is running. Please make sure your code defines such a function.
config FREERTOS_LEGACY_TICK_HOOK
bool "Enable legacy tick hook"
default n
help
If enabled, FreeRTOS will call a function called vApplicationTickHook when a FreeRTOS
tick is executed. Please make sure your code defines such a function.

menuconfig FREERTOS_DEBUG_INTERNALS
bool "Debug FreeRTOS internals"
default n
help
Enable this option to show the menu with internal FreeRTOS debugging features.
This option does not change any code by itself, it just shows/hides some options.
if FREERTOS_DEBUG_INTERNALS
config FREERTOS_PORTMUX_DEBUG
bool "Debug portMUX portENTER_CRITICAL/portEXIT_CRITICAL"
depends on FREERTOS_DEBUG_INTERNALS
default n
help
If enabled, debug information (including integrity checks) will be printed
to UART for the port-specific MUX implementation.
config FREERTOS_PORTMUX_DEBUG_RECURSIVE
bool "Debug portMUX Recursion"
depends on FREERTOS_PORTMUX_DEBUG
default n
help
If enabled, additional debug information will be printed for recursive
portMUX usage.
