BQ20Z65-R1_BQEVSW-SW: Can't find the file to download for the bqevsw-sw tool

Part Number: BQ20Z65-R1
Other Parts Discussed in Thread: BQ24735, BQ20Z65, EV2400, BQSTUDIO, BQEVSW,

I have a system with a bq24735 charge controller chip on the RRC-PMM240 battery management board, and a bq20z65 is the fuel gauge chip inside the RRC2020 smart battery pack.

I am not able to talk to these devices via bqStudio. Also, the bq20z65-R1-bqevsw-sw software tool is not available from the download page on ti.com.  I'm using a TI EV2400 interface between my laptop and system, with the SMBUS port connected to VCC, SDA, SCL and GND of the PMM240 board.

How can I get all this working?

Thanks,

Carl Olen

    Onyx, I installed the bqEVSW for the bq20z65-R1 and tried to run it. Please note: I have the EV2400 module; not the EV2300.

    I got multiple error messages:
    ‘The EV2300 connection could not be initiated! Please close this program and try again.’ Then I clicked OK and got the following error message.
    “bqEVSW ‘No USB board was detected! Please close this application first! Then make sure that the EV2300 is connected and then restart this program!’.

    Then I get the message: ‘The detected device is not compatible with this application! Proceed at your own risk.’

    In the status bar at the bottom of the display window, I see the message 'Communication Error'.

    Please let me know my next steps. to debugging this.
    Thanks,
    Carl Olen

    Did you run the installation file as an administrator, i.e right click, and select run as admin?

    Yes, I ran it as administrator, but this did not solve my problem. Also, I still have the question: Will this software work with my EV2400 instead of EV2300?

    Onyx,

    I uninstalled the program and then re-installed (again) as administrator. The message I got during the TI bq Evaluation Software 00.09.64 Setup reads

    “The EV2300 hardware does not support windows versions older than Windows 98 SE. The EV2300 driver has been verified to work on Windows 2000 and Windows XP only. If you have Windows 2003 or newer you may try to install the Windows 2000/XP drivers separately.”

    I then clicked OK to dismiss the installer.  After re-starting the re-installed program, I got the same exact behavior as before.

    So, should I try installing the “Windows 2000/XP drivers separately”? Does the EV2400 even have Windows 2000/XP drivers?

    NOTE: I am using Windows 10 Pro 2018 on my lab machine.  Does this make a difference?

    Please let me know.  Thanks,

    Carl

    Onyx,

    So, I found a download “EV2300a_Device_Driver_Installer_Multilanguage_0.6” from the link: https://e2e.ti.com/administrators1/battery_management/m/videos_files/458983

    And then I followed the instructions below.  For use of bqEVSW with EV2300, here are the recommended steps:

     Install unofficial 64-bit drivers for EV2300 from the zip archive attached to this post. Then restarted.

     Install the desired bqEVSW package from the corresponding gauge product folder on TI.com. (3362.sluc177.exe), then restarted. Note: I got the same message at the end of the installation: “The EV2300 hardware does not support windows versions older than Windows 98 SE. The EV2300 driver has been verified to work on Windows 2000 and Windows XP only. If you have Windows 2003 or newer you may try to install the Windows 2000/XP drivers separately.”

     Install as administrator the support components from this link: http://www.ti.com/lit/zip/sluc291, entitled “EV2400_Support_Components_20110524.exe” then, restarted.

    I then switched the USB input on my laptop to another port (the one marked with the "SS<network symbol> <battery symbol>"  And VIOLA!  It works

    Thanks,

    Carl
