Hi all,
I'm trying to use I2C.
I configured below in menuconfig.
- System Type > STM32 Peripheral Support > [*] I2C1
- Device Drivers > [*] I2C Driver Support
then compilation was done successfully.
But no I2C device( like /dev/i2c1 ) showed up when I tried ls /dev
Do I forget something to do?
I'
Hi Yuta,
Yes, you forgot to select the I2C Character driver support.
Please try to follow this tutorial:

If you want to use the I2C tool, you'll also have to register the i2c
driver from your board logic.
See:

Hi Alan,
Thank you for the link. I watched it!
Sorry I forgot to say that I've configured ` I2C Character driver
support ` as well.
However, /dev/i2c1 (or something like this) did not show up.
I'm going to try to register i2c driver.

The is a deficiency in the driver and should be pretty easy to fix by
passing the I2C address during driver initialization. Other drivers

And FYI, not exactly related to this topic but correlated:
Console will always be at ttyS0, even if the UART peripheral is not 0.

That is true for all architectures except for the STM32 families (all of
them). For the STM32's, that is true by default. For example, if the
