CONFIG_FREERTOS_OPTIMIZED_SCHEDULER
Enable FreeRTOS pĺatform optimized scheduler
Found in: Component config > FreeRTOS
On most platforms there are instructions can speedup the ready task searching. Enabling this option the
FreeRTOS with this instructions support will be built.
Default value:
• Yes (enabled)
CONFIG_FREERTOS_HZ
Tick rate (Hz)
Found in: Component config > FreeRTOS
Select the tick rate at which FreeRTOS does pre-emptive context switching.
Range:
• from 1 to 1000
Default value:
• 100
CONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION
Halt when an SMP-untested function is called
Found in: Component config > FreeRTOS
Some functions in FreeRTOS have not been thoroughly tested yet when moving to the SMP implemen-
tation of FreeRTOS. When this option is enabled, these fuctions will throw an assert().
Default value:
• Yes (enabled)
CONFIG_FREERTOS_CHECK_STACKOVERFLOW
Check for stack overflow
Found in: Component config > FreeRTOS
FreeRTOS can check for stack overflows in threads and trigger an user function called vApplication-
StackOverflowHook when this happens.
Available options:
• No checking (FREERTOS_CHECK_STACKOVERFLOW_NONE)
Do not check for stack overflows (configCHECK_FOR_STACK_OVERFLOW=0)
• Check by stack pointer value (FREERTOS_CHECK_STACKOVERFLOW_PTRVAL)
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)
• Check using canary bytes (FREERTOS_CHECK_STACKOVERFLOW_CANARY)
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)
CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK
Set a debug watchpoint as a stack overflow check
Found in: Component config > FreeRTOS
