How can i access the Coresight Component in Hikey 960?

Products Support HiKey 960

Hi,

The hardware manual tells that the Coresight debug and trace functionalities are implemented in HiKey 960. However, no detailed information is provided. As far as i know, the component like ETM and CTI are controlled by some memory mapped registers. But i don’t really know the addresses of these registers on HiKey960. Is there anyone happen to know something about this?

Thanks for any discussion and help!

Best Regards,
Zhenyu
