Although having no real world experience in embedded Linux development, I was deeply interested about the subject. I therefore read many books on the subject and the sad part is there is nothing that cannot be found online. I basically wasted money on the book, I therefore present summary of what I read and plenty of web references so that you save money on those books !.<\/p>\n
Step 1 – Learning how to develop a Linux distro by hand<\/strong> <\/span><\/p>\n There are plenty of projects that help you do this , only difference is that them most books make use of uclibc or newlib instead of the standard glibc . These are the set of resources that will help you get started on rolling a base linux \u00a0system from scratch. Also vim is one true editor, learn to use vim – use vim as the IDE ,period.<\/p>\n The modulus of operandi is as follows<\/p>\n NOTE: if you are completely new to linux environment , you should check out the guide and tutorials in tldp.org \u00a0( The Linux Documentation Project )\u00a0<\/strong><\/p>\n Step 2 – Learn and play around with POSIX API<\/strong><\/span><\/p>\n Linux is after all a POSIX complaint system there are plenty of resources available to learn \u00a0POSIX programming .<\/p>\n Step 3- Learn various Linux File systems<\/strong><\/span><\/p>\n Conventional ones include ext based on ones and those with journaling support \u00a0brtfs , jfs ,xfs , ReisesFS . Linux supports something known as VFS – or virtual files system which provides a generic interface that is used across files systems . The concept is very similar to inheritance concept in C++ , although Linux kernel is written in C , VFS is a good example that shows that modularity can be attained even if the underlying language does not support it .<\/p>\n Linux includes support for various embedded file systems like f2fs , – file system optimized for nand flash , read only squashfs file system \u00a0, tmpfs for storing stuff in ram. \u00a0The \u00a0mtd devices are found in \/proc\/mtd \u00a0. Typical embedded file systems include jffs2 \u00a0, yaffs2 , ubifs ,<\/p>\n Step4 Learn about device drivers and about the linux kernel<\/strong><\/span><\/p>\n Programming device drivers :\u00a0http:\/\/lwn.net\/Kernel\/LDD3\/<\/a>\u00a0. \u00a0 The best book on linux kernel in my opinion is by Bovet and Cesati. http:\/\/www.amazon.com\/Understanding-Linux-Kernel-Third-Edition\/dp\/0596005652<\/a>\u00a0. It is very well worth your money . But never hesitate to play around and tinker with stuff ! . \u00a0After this you have probably gained mastery over all aspects !. \u00a0I am listing few libraries that came to my head \u00a0. The list is no where near complete.<\/p>\n <\/strong>Light Weight Libraries\/Tools to look at<\/strong><\/span><\/p>\n C Libraries:<\/p>\n Networking:<\/p>\n For Graphics :<\/p>\n\n
