From 1cec005f8fe9eeb0cfa8e42af9245449c18ec61b Mon Sep 17 00:00:00 2001 From: Karl Palsson Date: Wed, 1 Oct 2025 10:43:22 +0000 Subject: examples/device/*_freertos: expand stack size when needed All four of these examples immediately crashed on stack overflow when connected, at least on a FRDM_K64F board. In 46fd82299040f the default freertos stack size was increased, but _only_ for stm32? Perhaps either all platform examples need the default increased, rather than increasing the problem task stacks as is done here.
