1.2 Software Installation

Find the latest software version of bqStudio-test and the EV2400 driver on ti.com. Search for the BQ27Z746 part number to get to the tool folder for the device. Following these steps to install the BQ27Z746 bqStudio software.

  1. Run the Firmware updater tool installer. Take note of the location where the Firmware Updater tool is installed on the computer.
  2. Connect the EV2400 that is to be updated to the computer.
  3. Ensure that no other EV2400 is connected to the computer being used for the firmware update.
  4. Go to the location of the Firmware Updater tool installed. Run the Firmware Updater tool.
  5. The updater tool should detect the connected EV2400, display the current firmware version, and prompt the user to continue to update the EV2400 firmware.
  6. Type Y and press Enter.
  7. The Firmware Updater tool should place the EV2400 into FW Update mode, perform a mass erase of the older EV2400 version's firmware, program the EV2400, and then reset the device. The tool will prompt the user to continue when finished.
  8. Press Enter to close the Firmware Updater tool.
  9. Unplug the EV2400 from the personal computer (PC).
  10. Open the archive containing the installation package of bqStudio and copy its contents into a temporary directory.
  11. Rename any previous Battery Management Studio folder by adding a version to the end.
  12. Open the bqStudio installer file that was downloaded from the TI website.
  13. Follow the instructions on-screen until completing the software installation.
  14. Before launching the evaluation software, connect the EV2400 USB cable to the computer and I2C port to the EVM board (J11).
Note: The EV2400 should remain plugged into the computer during the entire firmware updating process.
