I'm using Olimex Lime-2 A20. Able to enable I2C0, I2C1 & I2C2 from "armbian-config". But unable to do same for the I2C3 & I2C4. By using "olinuxino-overlay" getting error as "command not found". Please help me to access TWI3 & TWI4 present on GPIO-3 connector.
We are not supporting the tool armbian-config, please ask Armbian community for it. If your image doesn't have olinuxino-overlay then you are using Linux image that we don't support. Please refer to this document on how to download Olimage image:
