有没有遇到这个问题:
[ 111.569123] m00_b_tc35874x 1-000f: i2c_rd: reading register 0x14 from 0xf failed
[ 112.568321] m00_b_tc35874x 1-000f: i2c_rd: reading register 0x14 from 0xf failed

配置的设备树是:在i2c1下面
tc358749x: tc358749x@0f {
compatible = "toshiba,tc358749";
#sound-dai-cells = <0>;
reg = <0x0f>;
//<&cru SCLK_MIPIDPHY_REF>
clocks = <&ext_cam_clk>;
clock-names = "refclk";
power-gpios = <&gpio2 3 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
int-gpios = <&gpio2 4 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
rockchip,camera-module-index = <0>;
rockchip,camera-module-facing = "back";
rockchip,camera-module-name = "TC358749XBG";
rockchip,camera-module-lens-name = "NC";
pinctrl-0 = <&hdmiin_gpios>;
status = "okay";
port {
ucam_out0: endpoint {
remote-endpoint = <&mipi_in_ucam0>;
clock-lanes = <0>;
data-lanes = <1 2 3 4>;
clock-noncontinuous;
link-frequencies =
/bits/ 64 <297000000>;
};
};
};
使用的buildroot文件系统,哪位遇到个读i2c失败的,帮忙看一下
