I've spent a couple of days googling and "all the AI'ng" this and I just can't find anything that will get my Orange Pi 5 or Orange Pi 3 Zero Pin 3 or 5 to do anything at all. 

 

First, I'm running:  v25.2.3 for Orange Pi 5 running Armbian Linux 6.1.99-vendor-rk35xx (similar for the zero)  

 

$ ls /dev/i2c*
/dev/i2c-0  /dev/i2c-10  /dev/i2c-2  /dev/i2c-6  /dev/i2c-7  /dev/i2c-9

 

$GPIO readall

SDA.5 |     IN |  3
SCL.5  |     IN |  5 

(it says OFF on the zero)

 

$sudo i2cdetect -y 2
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- UU -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

 

I've tried..

\boot\

overlays=i2c2

 

I've also tried overlay .dts to turn off uart_a (shares the same pins)

 

/dts-v1/;
/plugin/;

/ {
        fragment@0 {
                target = <&i2c2>;
                __overlay__ {
                        status = "okay";
                };
        };

        fragment@1 {
                target = <&uart_A>;
                __overlay__ {
                        status = "disabled";
                };
        };
};

 

No matter what I do the pins are all high, zero signal at all ever.  What am I missing?

 

Thanks!
