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.

default n

help
|
|
FreeRTOS can check if a stack has overflown its bounds by checking either the value of
|
|
the stack pointer or by checking the integrity of canary bytes. (See FREERTOS_CHECK_STACKOVERFLOW
|
|
for more information.) These checks only happen on a context switch, and the situation that caused
|
|
the stack overflow may already be long gone by then. This option will use the debug memory
|
|
watchpoint 1 (the second one) to allow breaking into the debugger (or panic'ing) as soon as any
|
|
of the last 32 bytes on the stack of a task are overwritten. The side effect is that using gdb, you
|
|
effectively only have one watchpoint; the 2nd one is overwritten as soon as a task switch happens.
|
|
|
|
This check only triggers if the stack overflow writes within 4 bytes of the end of the stack, rather than
|
|
overshooting further, so it is worth combining this approach with one of the other stack overflow check methods.
|
|
|
|
When this watchpoint is hit, gdb will stop with a SIGTRAP message. When no OCD is attached, esp-idf
|
|
will panic on an unhandled debug exception.
