Teaching Embedded Linux Using File Abstractions

Wed 11:30am-12:55am

Much about an embedded platform and Linux itself can be understood through the file-operation abstractions provided in the driver model and virtual file systems. We’ll dive specifically into sysfs, procfs, debugfs and configfs in an exploration of the E-ALE hardware kit from the command-line shell. The Linux Standard Base and Kernel ABI will be introduced as tools to build a common expectation of what to find on any Linux system. Students will build familiarity with the E-ALE hardware, including peripherals connected to the GPIO, ADC, PWM, I2C, SPI, UART and USB processor interfaces, preparing them for subsequent E-ALE workshops.
