The device trace port is not pinned out and is instead only connected to the Embedded Trace Buffer. The ETB has a 4KB buffer memory. ETB enabled debug tools are required to read/interpret the captured trace data. This device uses ETM9™ version r2p2 and ETB version r0p1. Documentation on the ETM and ETB is available from ARM Ltd. Reference the ' CoreSight™ ETM9™ Technical Reference Manual, revision r0p1' and the 'ETM9 Technical Reference Manual, revision r2p2'. 3.3.7 ARM Memory Mapping By default the ARM has access to most on and off chip memory areas, EMIFA, EMIFB, and the additional 128K byte on chip SRAM. Likewise almost all of the on chip peripherals are accessible to the ARM by default. To improve security and/or robustness, the device has extensive memory and peripheral protection units which can be configured to limit access rights to the various on/off chip resources to specific hosts; including the ARM as well as other master peripherals. This allows the system tasks to be partitioned between the ARM and DSP as best suites the particular application; while enhancing the overall robustness of the solution. See Table 3-2 for a detailed top level device memory map that includes the ARM memory space. 10 Device Overview Copyright © 2010–2014, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: AM1705 |
