Hello everyone,
I’m currently working on a project that requires the ARM Coresight hardware tracing feature on BB AI-64, and planning to use the kernel version v6.12.13-ti-arm64-r25 from the official repository:
I enabled the Coresight feature in the kernel config:
CONFIG_CORESIGHT=y
CONFIG_CORESIGHT_LINKS_AND_SINKS=y
CONFIG_CORESIGHT_LINK_AND_SINK_TMC=y
CONFIG_CORESIGHT_CATU=y
CONFIG_CORESIGHT_SINK_TPIU=y
CONFIG_CORESIGHT_SINK_ETBV10=y
CONFIG_CORESIGHT_SOURCE_ETM4X=y
CONFIG_CORESIGHT_CTI=y
CONFIG_CORESIGHT_CTI_INTEGRATION_REGS=y
But I’m not very familiar with the device tree, so I wonder wether I need to make any modifications or just to keep the default.
Thanks.
