Basic Operation
The HDK is designed to work with TI’s Code Composer Studio and other third party ARM IDEs. The IDE
communicates with the board through the embedded emulator or an external JTAG emulator. To start,
follow the instructions in the Quick Start Guide to install Hercules-specific software. This process will install
all of the necessary development tools, documentation and drivers.

Memory Map
The TMS570LS31 family of MCUs have a large byte addressable address space.
shows the
address space of a TMS570LS3137 microcontroller on the left with specific details of how each region is
used by the HDK on the right. By default, the internal memory sits at the beginning of the address space.
The SDRAM is mapped into CS0 space on the EMIF. CS[4:2] are used for synchronous memory for
example SRAM, NOR Flash, NAND Flash, and so forth.
To use EMIF, the MPU has to be enabled, and the CS regions have to be configured as “device mode” or
“strongly ordered mode” through MPU.
