Prodigy 110 points
Part Number: SK-AM62B-P1
Other Parts Discussed in Thread: SK-AM62-LP, TPS65219

As I refered SK AM62B-P1 the pmic used is TPS6521904RHBR . Can you help me in configuring it through dts corresponding to this

    Hi Manjunath,

    Somehow there was a typo during the thread dispatch and your query wasn't delivered to anyone. Sorry for the mistake.

    Now I just saw your question, but since 2 months have been passed, do you still need assistance on this matter?

    yes we still require support for that

    Hi Manjunath,

    The SK-AM62B-P1 dts doesn't have tips65219 support yet, but you could refer to k3-am62-lp-sk.dts.

    refering k3-am62-lp-sk.dts I edited the am625-sk.dts and I got the above error

    Hi Manjunath,

    After compared the board schematics between SK-AM62B-P1 and SK-AM62-LP, they use different configurations of TPS65219, so the DTS PMIC node in k3-am62-lp.dts cannot be directly copied to sk-am625-sk.dts.

    What function do you miss if kernel dts doesn't have TPS65219 information?

    Above i have provided what i changed in the dts , can you verify it with the am62b-p1 schematics.also attached the error i got.

    The dev team is working on it but the software is not ready yet.

    What function do you miss without the kernel PMIC driver support?

    Its working fine without configuring pmic in device.

    Please wait for the PMIC enabled in the SDK. You can continue using the SDK on the EVM without the PMIC driver at this moment.
