fred0815 Posted January 12, 2022 Posted January 12, 2022 Thanks, i took this Image now, and installed xorg, it works now with wiringpi. Network is doing also. dmesg | grep sound says no soundcard found, but i see the HDMI-Sound. Maybe it is easier to get a USB-Soundcard to get sound properly working. 0 Quote

Smartyn34 Posted April 5, 2023 Posted April 5, 2023 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-1 i2c mv64xxx_i2c adapter I2C adapter i2c-2 i2c mv64xxx_i2c adapter I2C adapter spravce@bananapim3:~$ 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: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- 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. 0 Quote

Do you need an Armbian image for you? Did you take this from Ubuntu? 8 часов назад, Smartyn34 сказал: 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>; }; 0 Quote
Smartyn34 Posted April 23, 2023 Posted April 23, 2023 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>; }; spravce@bananapim3:~$ sudo i2cdetect -y 3 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: 20 21 -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- 0 Quote
Thomas1974 Posted July 27, 2023 Posted July 27, 2023 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 0 Quote
RES Posted September 27, 2024 Posted September 27, 2024 Does anyone know how to extract (old) Allwinner eGON files from the BPI M3 with dumpimage (or other Linux software?) To change the HDMI screen resolution. (720P is too big for TV/monitor, need 1360x768). dumpimage -l BPI_M3_720P.img Allwinner eGON image, size: 32768 bytes 0 Quote
