All PS Trace sources insert a 3-bit non-configurable ID in the packet to allow software to distinguish between packets from different sources. The ID that is inserted in the packet by the FTM is 010, which conflicts with the ID that is used by the ITM for 16-bit packets. Pack the ITM withones (1)to avoid the possibility of packet compression that can change the size of the packet 78 to 16.
Minor, there are restrictions on the usage of the FTM concurrent with the ITM.
Systems that use the FTM debug trace frames.

A potential way to get around this issue is to pad the ITM packets withones (1)to prevent their size after compressionfrom ever becoming 16. This mechanism is currently used in Xilinx tools.
