Update the DSTREAM-PT system firmware

The DSTREAM-PT system firmware contains:

  • The operating system that runs on the DSTREAM-ST unit.

  • Templates that define how the debug hardware communicates with different target devices.

  • Configuration files to load into any add-on probe units, such as the Parallel Trace probe.

Firmware updates are supplied with Arm® Development Studio.

Before you begin

  • Ensure you connect and power-up the DSTREAM-PT system so the firmware on both the DSTREAM-ST unit and Parallel Trace probe is updated simultaneously. For more information, see Connect and power up the DSTREAM-PT system.

  • You must ensure that the current DSTREAM-PT system firmware is at least the minimum version required by Arm Development Studio.

  • You must ensure that Arm Development Studio is installed on the host PC.

    Note

    In Arm Development Studio, the latest firmware files are available at: <Arm_Development_Studio_install_directory>/sw/debughw/firmware/.

Warning

You must have firmware version 5.0.0, or later, installed for the Parallel Trace probe to be detected.

If earlier firmware is installed, the DSTREAM-ST unit does not function as part of a DSTREAM-PT system. Instead, the DSTREAM-ST unit functions only as a DSTREAM-ST unit and is limited to 4-bit streaming trace.

Procedure

  1. Open the Debug Hardware Firmware Installer view: from the main menu in Arm Development Studio, select Window > Show View > Debug Hardware Firmware Installer.

  2. For the Debug Hardware field, click Browse... and Select your debug unit, then click Connect.

    Result: You can view the currently installed firmware version, the auto-selected new firmware file, and the new firmware details.

  3. Accept the auto-selected firmware update file, or browse and select a different firmware update file. Either:

    • To accept the auto-selected firmware update file, click Install.

    • To select a different firmware update file, in Select Firmware Update File, click Browse, select your firmware update file, and click Open. Click Install.

Results

The firmware is now updated on both the DSTREAM-ST unit and Parallel Trace probe.
