See TMC architectural state machine. The TMC is not training because of the DrainBuffer bit of the FFCR being set. In ETR configuration, the AXI interface is not busy. This case can be used to detect page table reads in scatter-gather mode when in Stopped state. [1] Triggered The ...
depends on CORESIGHT_LINK_AND_SINK_TMC help Enable support for the Coresight Address Translation Unit (CATU). CATU supports a scatter gather table of 4K pages, with forward/backward lookup. CATU helps TMC ETR to use a large physically non-contiguous trace buffer by translating the addresses us...
The maximum value that can be written into this register is MEM_SIZE - 1, in this case, the Full bit output is asserted after the first 32-bit word is written to trace memory. Writing to this register other than when in Disabled state results in Unpredictable behavior. ...
the RRP register is incremented to the next memory word. When the TMC left the Disabled state and the trace memory is empty, this register returns0xFFFFFFFF. When operating in CB mode and the TMC left the Disabled state, this register returns0xFFFFFFFFin all ...
