I noticed, even without the GB-I2C0.dtbo enabled in uEnv.txt, that there is a /dev/i2c-0 device on the Giantboard. The documentation is silent on the default I2C device. What pins does this connect to?
When I enable GB-I2C0.dtbo, I now see /dev/i2c-0 and /dev/i2c-1. What pins does i2c-1 connect to?
I’m especially interested in which one connects to PC0 / PB31, which are marked on the graphic of the board here https://groboards.com/wp-content/uploads/2019/01/giantboard.png as SCL and SDA.
BTW, nice job on the simple giantboard-tools project. After working with Buildroot and Yocto, this is a welcome simplicity.
