Hi, I developed a custom carrier board with an I2C0 connection (pins 185 and 187 on the SOM). I’ve successfully flashed the device tree disabling unused pins, however I’m having problems trying to use the I2C.
First, I can’t easily tell which port the I2C corresponds to, which makes debugging it tricky. I tried running the I2CDetect utility on all the I2C ports, they all respond with “no acknowledge from address.” Are there any steps you might recommend to get to the bottom of this?
My first guess is to try reducing the I2C bus speed, but I’m not sure which I2C bus corresponds to I2C0 so I feel like I’m hacking away blindly.
