80 | * Image Types | |
81 | * | |
82 | * "Standalone Programs" are directly runnable in the environment | |
83 | * provided by U-Boot; it is expected that (if they behave | |
84 | * well) you can continue to work in U-Boot after return from | |
85 | * the Standalone Program. | |
86 | * "OS Kernel Images" are usually images of some Embedded OS which | |
87 | * will take over control completely. Usually these programs | |
88 | * will install their own set of exception handlers, device | |
89 | * drivers, set up the MMU, etc. - this means, that you cannot | |
90 | * expect to re-enter U-Boot except by resetting the CPU. | |
91 | * "RAMDisk Images" are more or less just data blocks, and their | |
92 | * parameters (address, size) are passed to an OS kernel that is | |
93 | * being started. | |
94 | * "Multi-File Images" contain several images, typically an OS | |
95 | * (Linux) kernel image and one or more data images like | |
96 | * RAMDisks. This construct is useful for instance when you want | |
97 | * to boot over the network using BOOTP etc., where the boot | |
98 | * server provides just a single image file, but you want to get | |
99 | * for instance an OS kernel and a RAMDisk image. | |
100 | * | |
101 | * "Multi-File Images" start with a list of image sizes, each | |
102 | * image size (in bytes) specified by an "uint32_t" in network | |
103 | * byte order. This list is terminated by an "(uint32_t)0". | |
104 | * Immediately after the terminating 0 follow the images, one by | |
105 | * one, all aligned on "uint32_t" boundaries (size rounded up to | |
106 | * a multiple of 4 bytes - except for the last file). | |
107 | * | |
108 | * "Firmware Images" are binary images containing firmware (like | |
109 | * U-Boot or FPGA images) which usually will be programmed to | |
110 | * flash memory. | |
111 | * | |
112 | * "Script files" are command sequences that will be executed by | |
113 | * U-Boot's command interpreter; this feature is especially | |
114 | * useful when you configure U-Boot to use a real shell (hush) | |
115 | * as command interpreter (=> Shell Scripts). | |
