Looking to /boot/dtb-6.6.30-current-sunxi64/allwinner/overlay/ for h616 not exit dtbo sun50i-h616-w1-gpio.dtbo So for this reason not available in armbina-config in HARDWARE setup w1-gpio so we can not at current use 1-Wire sensor to define on which GPIO is connected 1-Wire sensor DS18B20 uses the 1-wire bus so it will be nice to have possibility use 1-Wire sensors with OZPI v3

Hi, I am not sure but in HARDWARE armbian-config when we set [*] w1-gpio (on for example OZPI v1 with ArmBian v23) is only set automatic loading modules during start up system? modprobe wire modprobe w1-gpio modprobe w1-therm I do this manually and I see exist path in system /sys/bus/w1/devices/ but we need know how to set number GPIO to use 1-Wire hardware, on Armbian v23 (Debian v11) it was added in /boot/armbianEnv.txt param_w1_pin=PA14 param_w1_pin_int_pullup=1 but how do this in Armbian v25 (based on Debian v12) so if I would like to connect my thermal sensor to GPIO 74 (PC10) I should be set in armbianEnv.txt ? param_w1_pin=PC10 param_w1_pin_int_pullup=1

For information purposes, that the 1.3-inch SH1106 OLED connected to I2C on OZPI v3 works very well OLED connected to PIN 3 of SDA and PIN 5 of SCK and in armbian-config in HARDWARE set to [*] i2c3-ph Using tools i2cdetect -y shows that the OLED is at address 0x3c All Python code with the adafruit library works fine

I have question. OZPI v3 has support for hardware DS18B20 thermal sensor via w1-gpio ? In armbian-config when we got to the “system” section and select “Hardware” is not existing w1-gpio or OZPI v3 has not support for w1-gpio hardware ? Does not work because there is no device tree file (in the /boot/dtb/allwinner/) and we need to create it ??? like for OZPI v2 ?: 1. Create text file "sun50i-h616-w1-gpio.dts" /dts-v1/; / { compatible = "xunlong,orangepi-zero2\0allwinner,sun50i-h616"; fragment@0 { target = <0xffffffff>; __overlay__ { w1_pins { pins = "PC9"; function = "gpio_in"; phandle = <0x01>; }; }; }; fragment@1 { target-path = [2f 00]; __overlay__ { onewire@0 { compatible = "w1-gpio"; pinctrl-names = "default"; pinctrl-0 = <0x01>; gpios = <0xffffffff 0x02 0x06 0x00>; status = "okay"; }; }; }; __symbols__ { w1_pins = "/fragment@0/__overlay__/w1_pins"; }; __fixups__ { pio = "/fragment@0:target:0\0/fragment@1/__overlay__/onewire@0:gpios:0"; }; __local_fixups__ { fragment@1 { __overlay__ { onewire@0 { pinctrl-0 = <0x00>; }; }; }; }; }; 2. After you need to compile it, with command "dtc -O dtb -o sun50i-h616-w1-gpio.dtbo sun50i-h616-w1-gpio.dts" 3. Copy it too /boot/dtb/allwinner/overlay/

Yes, I confirm the OZPI v3 UART5 described in the original documentation and as /dev/ttyS5 in ArmBian it is marked as /dev/ttyS1 and works correctly

I try to find where is problem with UART5 dmesg |grep serial [ 1.306076] sun50i-h616-pinctrl 300b000.pinctrl: pin-224 (5000000.serial) status -517 [ 1.306095] dw-apb-uart 5000000.serial: Error applying setting, reverse things back [ 1.306231] sun50i-h616-pinctrl 300b000.pinctrl: pin-226 (5001400.serial) status -517 [ 1.306249] dw-apb-uart 5001400.serial: Error applying setting, reverse things back [ 1.333692] 5000000.serial: ttyS0 at MMIO 0x5000000 (irq = 296, base_baud = 1500000) is a 16550A [ 1.334902] 5001400.serial: ttyS1 at MMIO 0x5001400 (irq = 297, base_baud = 1500000) is a 16550A dmesg don't show ttyS5 only ttyS0 and ttyS1 so UART5 on PIN26 header is ttyS1 not ttyS5 ?

I'm using Armbian an OZPI v3 beta with the kernel: Linux localhost 6.6.23-current-sunxi64 #3 SMP Tue Mar 26 22:22:53 UTC 2024 aarch64 GNU/Linux In armbian-config UART5 is enabled and: ls -al /dev/ttyS5 crw-rw---- 1 root dialout 4, 69 Mar 31 09:49 /dev/ttyS5 I am trying to use communication via serial port UART5 /dev/ttyS5 but without success.
