Software Defined Peripherals in Linux Using Zephyr and RPMsg
The presentation explains how to leverage asymmetric co-processors of modern SoCs on the example of i.MX6SoloX and Udoo Neo board. The embedded Cortex-M4 core is running Zephyr RTOS which implements various low speed serial peripherals (UART, SPI, I2C) in software using GPIO. Cortex-M4 communicates with the embedded Cortex-A9 core running Linux Kernel using the RPMsg protocol. On the Linux side a kernel module is used to present implemented serial peripherals to the user space as regular serial, SPI or I2C interface (e.g. /dev/ttySx). The benefits of such approach consist in the possibility of extending existing set of peripherals without any additional hardware cost and the possibility to place selected peripheral at virtually any available GPIO pin. Thanks to exporting the interfaces to the user space, it can be accessed for example by a Python script.
