11 bqConfig

11.1 Configuration Tool

For research, development, and testing purposes the bq27545 EVSW can be used to view and log RAM

registers as well as to view and modify certain DATAFLASH settings. However, TI also provides another

standalone software tool called bqConfig which can be used to program the most common DATAFLASH

registers, to perform calibration, and to generate a final image file that can be used in mass production.

The wizard in bqConfig guides the user through the process to create a .dmi file, which contains all the

DATAFLASH data of bq27545. Furthermore, bqConfig can also generate the .dffs file that is typically used

to program the bq27545 in mass production.

The bqConfig tool can be downloaded from the bq27545 product page at power.ti.com.

12 Send HDQ Screen

To configure a bq27545 into HDQ mode, navigate to the Send HDQ screen. It is possible that all the

screen options on the left are not visible depending on screen resolution. If needed, scroll within the left

menu to access the Send HDQ link. Click on the "Change comm to HDQ8" button while having the

bq27545 connected to the EV2300/EV2400 via I

C. Clicking on the button causes a message to appear

indicating that the process is not reversible and to confirm if the actions are desired. Also, it explains what

to do once the HDQ mode has been activated.

Once converting the bq27545 into HDQ mode, it is required that you connect the HDQ terminal of the

EV2300/EV2400 with the HDQ connector (J4) of the bq27545 EVM, then restart the EVSW, and select the

"bq27545HDQR1" with the proper firmware version from the list of supported devices within the EVSW.
