TCA9535: i2cdetect检测不到TCA9535

我使用ZU47DR的AXI IIC去控制TCA9535,我的blockdesign如下：

我使用petalinux2023.1制作镜像文件，设备树配置如下：

&axi_i2c1 {

    clock-frequency = <400000>;

    status = "okay";
    tca9535@20 {

       status = "okay";
        compatible = "ti,tca9535";
        reg = <0x20>;
    };
};

我能够在linux 系统中找到设备文件，和驱动

但是我通过i2cdetect检测不到tca9535,我通过应用层程序去读写tca9535寄存器也不能够成功，谁能帮助我一下，谢谢
