We have two I2C devices. One is a smart battery, one is standard speed battery. The smart battery (SMBus specification ) flips periodically between master and slave and the manufacturer (RRC Germany ) thinks this should go on its own bus if possible. I can’t see that the I2C-17 (Standard device, I2C1) on the iMX8X is a unique bus. Am I best putting this SMBUS device on the I2C1, and then make enable I2C0 on pins SODIMM 140=SCL and 142=SDA and use that for the other I2C device?
