· Take any device that doesn’t work on Linux, but has a very similar chipset to another device which does have a proven device driver for Linux. Try to modify the working device driver to make it work for the new device. If you achieve this, submit your code to the kernel and become a kernel developer yourself! Comments and acknowledgements. · I'm not entirely familiar with Linux SPI implementation but I would start by looking at omap2_mcspi_probe () function in drivers/spi/spi-omap2-mcspi.c file. As you can see there, it registers it's methods to Linux master SPI driver using this API: Linux/include/linux/spi/spi.h. Someone wanting to start become a kernel developer would generally go to The Linux Kernel Archives and start browsing the system to familiarize herself/himself with the resources available. Also necessary will be to download and install one of the common Linux distributions (distros) such .
To list all the device files use the below command. ls -l /dev. In the above output, we can see some other types of file types, some of them have B for a block device, C for character device some devices start with /dev/sda or /sdb. In Linux, the disk names are alphabetical. For example, dev/sda is the first hard drive, dev/sdb is the second hard drive, and so on. These devices are mass storage devices like memory sticks, hard drives, etc. Hence, sda means that this device was detected by. Linux device drivers. In this course attendees will learn how to develop and customize Linux device drivers. The following topics will be covered: Introduction to the Linux kernel architecture. Detailed study of the Linux kernel source code, configuring, compiling and booting the Linux kernel in the development kit. Take any device that doesn’t work on Linux, but has a very similar chipset to another device which does have a proven device driver for Linux. Try to modify the working device driver to make it work for the new device. If you achieve this, submit your code to the kernel and become a kernel developer yourself! Comments and acknowledgements.
Looking to change domain to Linux Device Drivers Embedded World looking for Start learning with basic concepts of Linux kernel like Kernel source code. The Developing Linux Device Drivers (LFD) program has been developed to provide learners with functional knowledge training of Linux in a professional. This instructor-led course is designed to show experienced programmers how to develop device drivers for embedded Linux systems, and give them a basic.
