How to use Jetson AGX Orin as an I2C Slave

[eteo4771]

Hi,

I’m trying to configure i2c-7@c250000 as an I2C slave on my Jetson AGX Orin. I’m using L4T 36.4.

I’ve looked through old forum topics about this issue, but most of them are for Nano, TX2. It seems the procedures cannot be directly applied to the AGX Orin.

Could you please provide the steps to configure I2C slave mode for AGX Orin?

Thanks in advance!

Please apply below patch for it on JP6 release.

The below is an example DT node for I2C slave configuration

i2c@xxxxxxxx {
    compatible = "nvidia,tegra-i2c-slave-byte";
    clock-frequency = <204000000>;
    /delete-property/dmas;
    /delete-property/dma-names;
    eeprom@65 {
        reg = <0x65>;
        compatible="slave-24c02";
        status = "okay";
    };
};
