Questions and Answers

9 questions
  • How Does the SAU100-USB V1 Compare to More Expensive JTAG Emulators?

    It's good value but downloads code more slowly than XDS510 or XDS560 class emulators. It has the essential debug features (breakpoints, single-step execution and memory access), so it suits development work where speed is less critical.

    Answered by John LeggUpdated 21 Sep 2025
  • Can I Use This Emulator with Custom Target Boards?

    Yes, provided your target board includes a standard TI 14-pin or 20-pin JTAG header and meets basic electrical requirements. Ensure proper ground connections and that your target processor is in the SAU100-USB supported device list.

    Answered by John LeggUpdated 14 Oct 2026
  • What Cable Length Limitations Should I Observe?

    Sauris does not publish a JTAG cable length limit for this emulator. On your own board, keep the JTAG header close to the target processor: TI’s JTAG design guidance says the signals must be buffered if the header is more than 6 inches (about 15cm) from the device. Longer or unbuffered connections may cause connection reliability issues, particularly in electrically noisy environments.

    Answered by John LeggUpdated 14 Oct 2026
  • Is the SAU100-USB V1 Compatible with Linux or Mac Operating Systems?

    Sauris lists Windows support only (Windows 2000, XP, Vista, 7, 8.1, 10 and 11). Sauris does not state Linux or Mac support. TI’s Code Composer Studio supports XDS100v2 class probes on Linux and macOS, but this has not been confirmed for the SAU100-USB, so Windows is the supported platform.

    Answered by John LeggUpdated 14 Oct 2026
  • How Do I Troubleshoot Connection Issues?

    Work through these checks:

    1. Check target power and the JTAG cable connections.
    2. Check the correct target configuration is selected in CCS and your processor is in the supported device list.
    3. Make sure no other debuggers are connected at the same time.

  • What Texas Instruments Processors Does the SAU100-USB V1 Support?

    The SAU100-USB v1 supports these TI processor families:

    • C2000 (TMS320F28x)
    • C5000 (TMS320C54x, C55x)
    • C6000 (TMS320C64x+, C674x)
    • ARM Cortex-R4 and ARM Cortex-A8

    It supports targets with a 14-pin or 20-pin TI JTAG header.

    Answered by John LeggUpdated 14 Oct 2026
  • Which Versions of Code Composer Studio Work with This Emulator?

    The SAU100-USB v1 requires Code Composer Studio V4.0 or newer. Sauris states that legacy CCS V3.3 is not supported, although it also offers a CCS 3.3 driver package for the SAU100-USB v2. CCS V4.1 includes support for the emulator, and the USB hardware is recognised automatically when it is plugged in after CCS is installed.

    Answered by John LeggUpdated 14 Oct 2026
  • Does the Emulator Require External Power or Drivers?

    It needs no external power, as it’s USB bus-powered. Code Composer Studio V4.1 includes support for the emulator, and the USB hardware is recognised automatically when it is plugged in after CCS is installed.

    Answered by John LeggUpdated 14 Oct 2026
  • What Target Voltages Are Supported?

    The emulator supports target systems with 1.8V and 3.3V IO levels. The current SAU100-USB (v.3) is specified for 1.65V to 5.5V JTAG interfaces, with output signals limited to 3.6V. The target voltage reference is the TVD (VTRef) pin on the JTAG connector, which also lets the emulator detect loss of target power.
