Hello,

 

is anyone here, who knows, how enable i2c on gpio pin5 and pin3 on M3?

I spend many days looking for solution, but without result.

 

in dtb file, I now have:


i2c2_ph_pins: i2c2-ph-pins {
                                pins = "PH4","PH5";
                                function = "i2c2";
                        };

i2c@1c2b400 {
                        compatible = "allwinner,sun8i-a83t-i2c\0allwinner,sun6i>
                        reg = <0x1c2b400 0x400>;
                        interrupts = <0x00 0x07 0x04>;
                        clocks = <0x02 0x34>;
                        resets = <0x02 0x27>;
                        pinctrl-names = "default";
                        pinctrl-0 = <&i2c2_ph_pins>;
                        status = "okay";
                        #address-cells = <0x01>;
                        #size-cells = <0x00>;
                };

i2cdetect: (with connected i2c device)

spravce@bananapim3:~$ sudo i2cdetect -l
i2c-0	i2c       	DesignWare HDMI                 	I2C adapter

i2c-2	i2c       	mv64xxx_i2c adapter             	I2C adapter

Hardware is ok, when I tried UBUNTU image, i2c worked normaly, but I need armbian.

 

pls help, I have 7pcs of Bpi M3, and without i2c, I can put it in the trash.

Do you need an Armbian image for you?

 

Did you take this from Ubuntu?

Thank for reply,

 

now i2c is working, I compared dts file from other dist (where i2c works) , and changed:

i2c0-pins {
				pins = "PH0\0PH1";
				function = "i2c0";
				phandle = <0x30>;
			};

			i2c1-pins {
				pins = "PH2\0PH3";
				function = "i2c1";
				phandle = <0x31>;
			};

i2c2-ph-pins {
				pins = "PH4\0PH5";
				function = "i2c2";
				phandle = <0x69>;
			};
                  
i2c@1c2ac00 {
			compatible = "allwinner,sun8i-a83t-i2c\0allwinner,sun6i-a31-i2c";
			reg = <0x1c2ac00 0x400>;
			interrupts = <0x00 0x06 0x04>;
			clocks = <0x02 0x32>;
			resets = <0x02 0x25>;
			pinctrl-names = "default";
			pinctrl-0 = <0x30>;
			status = "okay";
			#address-cells = <0x01>;
			#size-cells = <0x00>;
			phandle = <0x78>;
		};

i2c@1c2b000 {
			compatible = "allwinner,sun8i-a83t-i2c\0allwinner,sun6i-a31-i2c";
			reg = <0x1c2b000 0x400>;
			interrupts = <0x00 0x07 0x04>;
			clocks = <0x02 0x33>;
			resets = <0x02 0x26>;
			pinctrl-names = "default";
			pinctrl-0 = <0x31>;
			status = "okay";
			#address-cells = <0x01>;
			#size-cells = <0x00>;
			phandle = <0x79>;
		};

i2c@1c2b400 {
			compatible = "allwinner,sun8i-a83t-i2c\0allwinner,sun6i-a31-i2c";
			reg = <0x1c2b400 0x400>;
			interrupts = <0x00 0x08 0x04>;
			clocks = <0x02 0x34>;
			resets = <0x02 0x27>;
			pinctrl-names = "default";
                        pinctrl-0 = <0x69>;
			status = "okay";
			#address-cells = <0x01>;
			#size-cells = <0x00>;
			phandle = <0x7a>;
		};

Dear all,
probably my question is answered somewhere else, but I couldn't find it:

I'd like to under clock to 500MHz or 1 GHZ for example my M3.
This should be done to let it work longtime without overheating and also to reduce power consumption.....

Any clue how to do this?

Btw: I can't compile kernels or do things like that 🙂

Cheers
Thomas
