EV2300-084: Is there a driver that supports Windows 11 + EV2400 + BQ27520YZFT-G4?

Hello Kyohei,

Unfortunately, there is no specific driver that supports windows 11 and Ev2400. I would recommend making sure to use the latest driver for the EV2400 and seeing if that works.

Regards,

Adrian

Hi Adrian,

I understand.

I have two additional questions:

・Is the latest version of BqStudio 1.3.101? I see that version 1.3.127 (test version) is also available. What is the status of this version?

・When I wrote data to the BQ27520YZFT-G4 using EV2300 and BqStudio, communication with the EV2300 stopped. Is it possible to restore communication with the affected board?

Best regards,

Kyohei

Hello Kyohei,

We would highly recommend you to use the version 1.3.127 of BQStudio. We would also recommend you to use the EV2400.

Hi Adrian,

Thank you for your reply.

I will inform the customer to use version 1.3.127 of BQStudio.

Is it correct to understand that using the EV2400 can restore the board that has lost communication?

Best regards,

Kyohei

Hello Kyohei,

I can not guarantee that the EV2400 will restore communication but the EV2400 is the recommend tool to use for communication with our devices.

Hi Adrian,

Thank you for your reply.

By the way, is there a plan to support Windows 11? If so, when will it be available?

Best regards,

Kyohei

Hello Kyohei,

I can ask the team regarding this question.

Adrian

Hi Adriam,

Please confirm.

Kyohei

Hi Robert,

EV2300 and BQStudio do not work as expected on Windows 11, but does EV2400 and BQStudio work as intended on Windows 11?

Adrian mentioned that there are no specific drivers supporting Windows 11 and EV2400.

Best regards,

Kyohei

Hello Kyohei,

We had a recent discovery from another member of this forum and he was able to get Windows 11 to work with the Ev2300. Please check out these links:

Hi Adrian,

Thank you for you reply.

I checked the information from the links.

Does the “isolation memory” mentioned here refer to “Core isolation” in Windows 11? Is it safe to disable this feature in terms of security?

Also, with Windows 10 support ending next year, does TI plan to officially support Windows 11? If so, when is this expected to happen?

I apologize for asking multiple questions, but I appreciate your help.

Best regards,

Kyohei

Hello Kyohei,

I can not speak on how safe it would be to disable this feature. I can link this page from Microsoft: https://support.microsoft.com/en-us/windows/device-protection-in-windows-security-afa11526-de57-b1c5-599f-3a4c6a61c5e2

Might be a question to bring up with Microsoft Support team.

I am currently not aware of my team supporting windows 11 in the future. However, I can ask my advisor.

Hi Adrian,

Is there a way to restore communication with a board that has stopped working with Windows 11 + EV2300 + bqEVSW?

If you have any advice, please let me know.

Best regards,

Kyohei

Hello Kyohei,

What issue are you seeing? Is the device just completely not communicating anymore?

Regards,

Adrian

Hi Adrian,

My customer wrote data to the BQ27520YZFT-G4 using EV2300 and BqStudio 1.3.101, but then lost communication with the EV2300 and could no longer write data.

Even after changing the environment to BqStudio 1.3.127, EV2400, and Windows 10, communication could not be established.

This issue is occurring on two devices. Could you please provide any solutions to this problem?

Best regards,

Kyohei

Hello Kyohei,

Are you able to get a digital logic capture of the EV2400/2300 trying to communicate to the gauge?

Regards,

Adrian

Hi Adrian,

Is my understanding correct that a digital logic capture is like a communication record of digital signals when communicating via I2C?

Best regards,

Kyohei

Hello Kyohei,

Yes, that is correct. This is essential to debug any sort of communication based issues with ICs.

Adrian
