Another option from within the code is the following:

SET_LOOP_TASK_STACK_SIZE( 16*1024 ); // 16KB

setup()
{
	// setup code here
}

loop()
{
	// loop code here
}

#5173 (comment)

SET_LOOP_TASK_STACK_SIZE( 16*1024 ); // 16KB

That would be marvelous, but it does not work for me. What kind of versions of what are needed to make it work, and what else needs to be set/configured?

I stand corrected: it DOES work!

What it does NOT do, and which tripped me, is that it does NOT change the value CONFIG_ARDUINO_LOOP_STACK_SIZE. This remains at the default value, in my case 8192. But you see it from uxTaskGetStackHighWaterMark(<looptask>).

So thanks, this little command SET_LOOP_TASK_STACK_SIZE( 16*1024 ); // 16KB is very helpful!
