TDA4VM: TDA4VM

Hello,

Currently there is no peripheral or sensor that uses i3c on TDA4 EVM.
So there is no support for i3c drivers on linux in the sdk.

What is the peripheral/sensor that you are trying to develop?

Hello,

I found that latest Linux 5.6-rc2 has support for i3c drivers. So you can refer to that.
you can look at:

Thanks,

Hi Keerthy~

In our use case ,we use i3c to control the deseriliser (UB962)'s register which connected  with four serialized cameras.

If there is no i3c driver in the sdk, where can i get some support?

Best Regards!

Hi Keerthy,

Thanks for your help, will the i3c driver add in the future release of TDA4 Linux SDK ? 

Best Regards

Hi HuTian,

For my reference do you have the public data sheet link to the part you are trying out?

- Keerthy

Hi Keerthy:

i have the TDA4VM TRM_vInitial.pdf. Is it enough to developing I3C driver on my own?

HuTian

Hi HuTian,

I am asking for seseriliser (UB962)'s data sheet that you are referring.

- Keerthy

Hi Keerthy,

Of course, yes. And I think the SDK for RTOS already describes the UB960 which palced on the Fusion Board for Cam. I can refer to the Fusion Board developing UB962.

HuTian,

Could you paste the data sheet link for seseriliser (UB962)'s? Here?

- Keerthy

Keerthy,

Is there any problem for UB962? The datasheet is shown below:

Hi HuTian,

I was thinking you had some other data sheet. I referred to the same before as well.
I see no references to i3c in that data sheet. The UB962 might only support i2c and not i3c interface as
i do not see any documentation that confirms that. That is the reason i asked for the
data sheet.

Keerthy,

After discussing with HW team, I3C0_SCL & I3C0_SDA can pinmux as a I2C6. My mistake.

Thank you
