Guide to ARMLinux for Developers (PDF file 1.3MB, 2nd Edn, sent by email)

The Guide to ARMLinux for Developers includes some new chapters covering often-asked-about topics. These include one describing the process and practicalities of porting the ARMLinux kernel to a new architecture, including a discussion of symbols and macros and the layout and purpose of relevant kernel source files, as well as how to submit your work to the main tree. A second major addition is a description of the available bootloaders for ARM devices and the process of booting the kernel should you need to write or modify a bootloader for this purpose.

This is a preliminary version of the book in electronic form  (PDF).
