5 EVM Hardware and Software Setup

This section describes how to install the bq27545EVM PC software, and how to connect the different

components of the EVM.

5.1 System Requirements

The bq27545EVSW software requires Windows

XP if using EV2300 and Windows XP or newer if using

EV2400. Drivers for Windows 98SE are provided, but Microsoft no longer supports Windows 98; Windows

98 may have issues with USB driver support. The EV2300 USB drivers have been tested for Windows

98SE, but no assurance is made for problem-free operation with specific system configurations.

5.2 Software Installation

Find the latest software version in the bq27545 tool folder on power.ti.com. Make a search by part number

for bq27545 to access the tool folder.

5.2.1 Using EV2300

Use the following steps to install the bq27545EVSW software when using EV2300:

1. Ensure that the EV2300 is not connected to the PC through a USB cable before starting this

procedure.

2. Browse for the supported software link within the bq27545 TI web site product folder to find the

downloadable evaluation software (EVSW) installation files.

3. Open the software file that was downloaded from the TI web site.

4. Follow the instructions on screen until the software installation is completed.

5. Before starting the EVSW, connect the EV2300 to the computer using the USB cable.

6. Wait until the system prompt “new hardware found” appears. Choose “select location manually”, and

use the “browse” button to point to subdirectory TIUSBWin2K-XP-1.

7. Answer “continue” to the warning that drivers are not certified with Microsoft™.

8. After installation finishes, another system prompt "new hardware found" appears. Repeat steps 6 and

7, but specify the directory as TIUSBWin2K-XP-2.

9. Answer "continue" to the warning that drivers are not certified with Microsoft. Driver installation is now

finished.

5.2.2 Using EV2400

Use the following steps to install the bq27545EVSW software when using EV2400:
