119 helped a lot to load the I²C drivers. We can read and write to an Arduino Uno via /dev/i2c-0 (pins 13 and 15).
However, we found out that the frequency is set to 400 kHz (fast mode) by default.
We have a device that do not support fast mode, so i2cdetect does not detect it. How to change the bus speed to 100 kHz (standard mode) ?
For the Raspberry Pi, there is a config file, but we found nothing of the sort on the MinnowBoard.
Hi,
We are using Debian 10 x64.

Thanks in advance for your help!
