Phil,
Yes, the AM3359 supports MIPI STM and CCS can be used to configure the on-chip ETB to capture data. Since you have an XDS560v2 STM you can also use CCS to export STM data out the EMU pins to be collected by the XDS560v2 STM (with a much deeper trace buffers than the 32K ETB) if your target connects EMU0:4 to the XDS connector. If you only have EMU0:1 connected to the XDS connector then bandwidth could be an issue, but it will depend on your message density. There are three gel scripts used to configure the AM3359, one of which should be ran before you configure CCS to collect STM data:
Enable_ETB_STM_Trace
Enable_STM_4PinMode_Trace (configures EMU[0:4] for a clock pin and 4 data pins)
Enable_STM_1PinMode_Trace (configures EMU[0:1] for a clock pin and 1 data pin)
Also, once you have rebuilt the STM driver, to install the STM driver with insmod you will need the STM transport base address which for the AM3559 is 0x4B000000.
