Activate GPIO port

[mamin27]

I work at MangoPI with H616 processor. I installed there debian (11.6 version).

orangepi@orangepizero2:/etc$ sudo i2cdetect -l
i2c-1   i2c             DesignWare HDMI                         I2C adapter
i2c-0   i2c             mv64xxx_i2c adapter                     I2C adapter

orangepi@orangepizero2:/etc$ sudo i2cdetect -y 0

something is active there and listening at I2C network

I add modprobe file that is running with mv64xxxx chip, swith clock frequency to fast mode 400khz

orangepi@orangepizero2:/etc/modprobe.d$ cat mv64xxx.conf
options mv64xxx compatible="marvell,mv64xxx-i2c" clock-frequency=400000

some gpio test

orangepi@orangepizero2:/etc/modprobe.d$ sudo gpioinfo

I would like to activate I2C pins at GPIO port and test it. I have tested I2C IC's at RPI Zero and now I would like to run it also at MangoPi.

Could you give me some advice?

Is the device address of the mv64xxxx chip 0x30?

Not sure if there is a driver for mv64xxxx on your system，It looks like it is not enabled.

In your kernel I detected in case of H616 GPIO settings big differences towards current kernel version: https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/allwinner/sun50i-h616.dtsi

I2C port description is changed now.

Is there any way how to update/replace kernel version in your project?

Here is also some advice to fix i2c and gpio issues: https://github.com/orangepi-xunlong/orangepi-build/tree/main/external/packages/pack-uboot/sun50iw9/bin/dts

I do not quite understand what you mean, my kernel is modified on the basis of the kernel of Orange Pie： https://github.com/orangepi-xunlong/linux-orangepi/tree/orange-pi-5.16-sunxi64

You can refer to the original kernel section on i2c.

If you want to replace the kernel version, you can just replace the whole kernel folder, but I don't guarantee that it will compile.

I2C is working now.
