CoreSight on Nvidia Jetson

Hi there, I have two Nvidia Jetson Developer Kits, one AGX Xavier and one Nano. I want to use CoreSight for self-hosted trace collection (i.e. without JTAG debug probe) on these boards. I built the kernel for CoreSight configuration, but the problem is that there are no CoreSight devices at /sys/bus/coresight/devices/. Does anyone have an idea how to fix this? Any help is highly appreciated!

Best regards, Vincent
