I've attached my demo project. The sdkconfig.defaults as provided should result in a working app. Then delete sdkconfig, uncomment the option, and rebuild, and you should see the core panic. Can someone explain why adding the tick hook causes a core panic when initializing NVS? I kinda want to use the tick hook facility to run my own tick timer. Unless someone has a different way of attaching to the SysTick timer while running FreeRTOS...
