It is +important that the dtc used has support for binary includes -- refer to +www.jdl.com for its latest version. mkimage (together with dtc) takes as input +an image source file, which describes the contents of the image and defines +its various properties used during booting. By convention, image source file +has the ".its" extension, also, the details of its format are given in +doc/source_file_format.txt. The actual data that is to be included in the +uImage (kernel, ramdisk, etc.) is specified in the image source file in the +form of paths to appropriate data files. The outcome of the image creation +process is a binary file (by convention with the ".itb" extension) that +contains all the referenced data (kernel, ramdisk, etc.) and other information +needed by U-Boot to handle the uImage properly. The uImage file is then +transferred to the target (e.g., via tftp) and booted using the bootm command. + +To summarize the prerequisites needed for new uImage creation: +- mkimage +- dtc (with support for binary includes) +- image source file (*.its) +- image data file(s) + + +Here's a graphical overview of the image creation and booting process: + +image source file mkimage + dtc transfer to target + + ---------------> image file --------------------> bootm +image data files(s) + + +Example 1 -- old-style (non-FDT) kernel booting +----------------------------------------------- + +Consider a simple scenario, where a PPC Linux kernel built from sources on the +development host is to be booted old-style (non-FDT) by U-Boot on an embedded +target.
