The memory map table shows the address space of a TMS570LS31 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. CS2/3/4 are used for synchronous memory for example SRAM, NOR flash, NAND flash etc. Table 1, TMS570LS31 Memory Map Start End Address Address 0x0000 0000 0x002F FFFF 0x0800 0000 0x0803 FFFF 0x0840 0000 0x0843 FFFF 0x6000 0000 0x63FF FFFF 0x6400 0000 0x67FF FFFF 0x6800 0000 0x7BFF FFFF 0x8000 0000 0x87FF FFFF 7 HDK Flash RAM RAM-ECC CS2 Async RAM CS3 Async RAM CS4 Async RAM CS0 Sync SDRAM Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 1.8 Power Supply The HDK board operates from a single +12V external power supply connected to the main power input (P1), a 2.5 mm, barrel-type plug. Internally, the +12V input is converted into +1.2V, +3.3V and +5.0V using Texas Instruments swift voltage regulators and PTH power module. The +1.2V supply is used for the MCU core while the +3.3V supply is used for the MCU's I/O buffers and other module on the board. The +5.0 volt supply is used for ADC power (2nd option). There are multiple power test points on the HDK board. The three main test point pairs provide a convenient mechanism to check the HDK’s current for each supply. The table below shows the voltages for each test point and what the supply is used for.

The FTDI USB driver makes the FT2232H 2nd channel appear as a virtual COM port (VCP). This allows the user to also have standard PC serial communications with the HDK using the same USB interface as the on-board emulator 2.2.8 Daughter Card Interface The HDK provides expansion connectors that can be used to accept plug-in daughter cards. The daughter card allows users to build on their EVM platform to extend its capabilities and provide customer and application specific I/O. The expansion connectors are for all major interfaces including asynchronous memory, peripherals, Flexray, and A/D expansion. The pin outs for this interface are documented in Chapter 3.

The POR condition is intended to reset all logic on the device including the test/emulation circuitry. TMS570 MCU has two resets: Warm Reset (nRST) and Power On Reset (nPORRST. The POR can be invoked by pushing POR_RESET button, or by RESET signals from XDS100 CPLD, ARM JTAG SREST, or MIPI connector. 2.7 S3, System Reset Switch Switch S3 to assert a warm reset the TMS570LS31 device. However, a warm reset does not reset any on-chip test or emulation logic. The reset signal from the windowed watchdog will also assert a warm reset to MCU. 21 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide Appendix A Schematics This appendix contains the schematics for the TMS570LS31 HDK board. 22 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 23 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 24 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 25 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 26 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 27 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 28 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 29 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 30 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 31 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 32 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 33 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 34 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide 35 Texas Instruments Proprietary Information – Internal Data TMS570LS31 HDK User Guide Appendix B Operation Notices The user assumes all responsibility and liability for proper and safe handling of the boards.
