I've changed my reference BSP configuration to disable RTCS_MINIMUM_FOOTPRINT, as I need support for multicast. Unfortunately when I do this RTCS fails to initialize at run-time with error 1136 (I'm using MQX 4.0.1).
The RTCS startup is somewhat convoluted so it's not easy to debug/troubleshoot but I gathered that this is an RTCSERR_OPEN_QUEUE_FAILED when calling RTCS_task_create(). Is there some run-time dependency I need to change? I am running the "small_ram_config" defaults.
