In this case, I call mpu9250_register() which I made instead of
i2c_register().
/dev/i2c1 appeared with ls /dev.
However, `i2c dev -b 1 0x03 0x77 ` did not detect any i2c device.

Hi Yuta,

Please try to follow this tutorial:

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.

Alan,
Thank you for sharing the link.
I checked it and I understand CONFIG_USEC_PER_TICK(default 1) is
important when using some functions like usleep().
It won't work well if I try usleep(1) or shorter.
Thank you.

I'll try Tickless OS configuration if I need later.
Thank you very much.
