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 at 5401b000 [ 0.685119] of_amba_device_create(): amba_device_add() failed (-19) for /etm at 54010000 There are no nodes according coresight in /sys/kernel/debug/ . Best regards, Marcin
