Hi,

Support for TPIU > and SDTI are yet to be added. Did you tried running the drivers on board or are there any special preparation needed? I've BeagleBoard-xM Rev. C applied your patches and enabled the functions the in menuconfig. But on dmesg I see that:
[ 0.685028] of_amba_device_create(): amba_device_add() failed (-19) for /etb@5401b000 [ 0.685119] of_amba_device_create(): amba_device_add() failed (-19) for /etm@54010000
There are no nodes according coresight in /sys/kernel/debug/ .
Best regards, Marcin
