BQ27441EVM-G1B: BQ27441EVM-G1B driver support for U-boot

Part Number: BQ27441EVM-G1B

Hi,
I am using u-boot (version 1_2020.04-r0) on i.MX8M mini and BQ21441EVM-G1B. I am facing issue to implement driver of BQ27441 in u-boot.

Is there any driver for the bq27441 that is used in u-boot? or are there any docs available for the same implementation?
Any assistance would be highly appreciated.

Hello Hardevsinh,

The only drivers we have available for the gauges are located here: https://www.ti.com/tool/BQ27XXXSW-LINUX

I hope this helps you.

Thanks for your reply,

I already used this driver in kernel and it's worked.

Now i want to use BQ21441EVM-G1B from u-boot also.

Any pointers will be appreciated.

Hello Hardevsinh,

We do not provide direct support with all open-source software, I may not understand your question.

This gauge is a ROM based gauge, so upon POR the settings will be reset to default by the ROM. Your system will need to account for this during bootup. Flash based gauges require less setup upon POR and the configuration and learned data is saved. SLUA801 may be helpful for you to program data with Flash stream files upon startup.

Sincerely,

Wyatt Keller
