Tizen Developers

I'm using Tizen 4.0 headed image with ARTIK530.

I can access i2c devices on boards(RTC,..) with command.

(cat /sys/bus/i2c/devices/4-0068/rtc/rtc0)

but, how can I access some devices that I connect additionally?

i2c-tools package is not installed initially, so I can't use commands (i2cdetect, i2cset, i2cget)
