Hi,
Coresight tracing sources (STM and ETM) and ETF sink are supported in Linux in Orin.
The corresponding nodes in device tree need to be enabled: hardware/nvidia/soc/t23x/kernel-dts/tegra234-soc/tegra234-soc-coresight.dtsi
Below kernel config also needs to be enabled:
CONFIG_CORESIGHT=y
CONFIG_CORESIGHT_LINKS_AND_SINKS=y
CONFIG_CORESIGHT_LINK_AND_SINK_TMC=y
CONFIG_CORESIGHT_STM=y
CONFIG_CORESIGHT_SOURCE_ETM4X=y
ETR sink is not accessible currently.
