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: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

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!
