PROCESSOR-SDK-J722S: I2C4 bus is not available in device tree

Heiko Thiery

Tool/software:

Hi,

we have a design that has devices connected on this i2c bus (I2C4). But we do not see that there is node available in the k3-j722s-main.dtsi file. Is this just missing there?

Hello,

Can you please share the SDK version that you are using?

I do see that it is not part of the latest DTS files as well. Are you using that on your custom board?

Hi,

we do not use the SDK directly. We use the kernel 6.12 coming from the TI git as well the mainline kernel. Main plan is to use the mainline kernel.

Hello,

I have raised this with the development team. If this is not connected on the custom board let me know if you can sync with the next SDK version. The I2C4 doesn't interrupt the gic directly and needs to go via GPIO interrupt router.

Best Regards,

Keerthy
