Recently I come to about the IIoT solution of siemens which have Yocto Linux https://www.14core.com/siemens-simatic-iot2000-iot2020-iot2040-arduino-ide-integration/. As I am already working on raspberry pi and raspberry pi based Revolution Pi known as RevPi which uses raspbian based OS .here you will find the use full information about the RevPi https://revolution.kunbus.com.
I don't have much knowledge about these Linux based open-source Operating System. Can anyone help me to understand in what aspect Yocto Linux is different from Raspbian OS?
