EVM Hardware and Software Setup
This section describes how to install the bq20z70EVM-001 PC software, and how to connect the different
components of the EVM.
5.1
System Requirements
The bq20z70EVSW requires Windows 2000 or Windows XP. Drivers for Windows 98SE are provided, but
Microsoft no longer supports Windows 98; and there may be issues in Windows 98 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 bq20z70 tool folder on power.ti.com. Use the following steps to
install the bq20z70EVSW software:
1. Copy the files from the CD into the temporary directory you selected, in the folder "bq20z70 EV SW
Install", double-click on bqEVSWSetup00.09.32.exe and follow the installer instructions to complete the
bq20z70 EVSW installation.
2. If the EV2300 was not previously installed, after bq20z70 EVSW installation, a TI USB DRIVER
INSTALLER will pop up. Click "Yes" for the agreement message and follow its instructions.
3. Plug the EV2300 into a USB port.
4. The Win98 Driver can be found in the archive Win98EV2300Drivers-DocUpdateDec1703.zip under the
"EV2300 Drivers" folder.
If files were downloaded from the Web:
1. Open the archive containing the installation package, and copy its contents in a temporary directory.
2. Follow the preceding steps 1 - 4.

Troubleshooting Unexpected Dialog Boxes
Ensure that the files were extracted from the zip file using the Preserve Folder names option.
Ensure that all the files were extracted from the zip file.
The user that is downloading the files must be logged in as the administrator.
The driver is not signed, so the administrator must allow installation of unsigned drivers in the operating
system policy.
