i2c on tinkerboard


Recommended Posts

Hello, I'm trying to use i2c (i2c1, i2c4) with fresh installed image "Armbian_21.05.1_Tinkerboard_focal_current_5.10.34.img.xz".

 

The related overlays seems to be enabled by default:

cat /boot/armbianEnv.txt
verbosity=1
bootlogo=false
overlay_prefix=rockchip
overlays=i2c1 i2c4 spi2 spidev2 uart1 uart2
rootdev=UUID=68be20e3-93fc-4c59-95e1-0c534586d070
rootfstype=ext4
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

 

i2c is enabled by default:

i2cdetect -l
i2c-2	i2c       	rk3x-i2c                        	I2C adapter
i2c-0	i2c       	rk3x-i2c                        	I2C adapter
i2c-5	i2c       	rk3x-i2c                        	I2C adapter

 

What I have missed to setup?

 

Thanks Thomas
