📄️ 4-1 Indroduction
In this chapter, we will show you how to perform tests and develop program to control the GPIO hardware pins of Renesas RZ/G2L under the Linux environment
📄️ 4-2 Linux GPIO Driver
sysfs is a pseudo file system provided by the Linux kernel that exports information about various kernel subsystems, hardware devices, and associated device drivers from the kernel's device model to user space through virtual files. In addition to providing information about various devices and kernel subsystems, exported virtual files are also used for their configuration.
