Some examples will not work since the platform provides insufficient resources. In general the uGOAL examples will work ( iRJ45 / SoM - uGOAL Examples ). Examples from the 20215013_irj45 folder ( iRJ45 / SoM - GOAL examples ) may need additional resources. This is specially the case when web server and tcp/udp channels are used in addition to a fieldsbus protocol.
