Part Number: AM625
Other Parts Discussed in Thread: TPS65219

Hi TI Team,

We are working on the custom board based on AM625 and we are using PMIC IC which is connected over I2C 0. So what changes do we need to make in bootloader dts or any other changes we are required to make?

Hi Abhishek,

See here for the Linux device tree node for TPS65219: git.ti.com/.../k3-am62-lp-sk.dts

Here is the U-Boot device tree node for TPS65219: https://git.ti.com/cgit/ti-u-boot/ti-u-boot/tree/arch/arm/dts/k3-am62-lp-sk.dts?h=ti-u-boot-2023.04#n202

There is also modules related to TPS65219 in the .config file, but enabled by default in the SDK.

Best Regards,

Anshu

Hi, Anshu Madwesh,

Thanks for sharing.

Can I use it directly as it is? Because the PMIC that we are using "TPS6521903RHB" almost looks similar.
