zImage.img的制作？

mini2440 Linux
norFlash启动
uboot

bootcmd=nfs 0x30008000 192.168.0.1:/home/tekkaman/working/nfs/zImage.img;bootm

zImage.img这个镜像如何得到，用什么软件，哪里可以下载到？
为什么必须要用zImage.img，而不能用uImage或者zImage文件？
多谢指教。

在u-boot-2010.03-tekkaman-master\tools文件夹下有mkimage.c和mkimage.h make后生成mkimage 但是我在开发板输入mkimage出现以下 [u-boot@MINI2440]# mkimage Unknown command 'mkimage' - try 'help' 我在PC虚拟机redhat Linux下出现以下 /U-boot-2009.11_tekkaman-master/tools [root@localhost tools]# ./mkimage [root@localhost tools]# ./mkimage Usage: ./mkimage -l image -l ==> list image header information ./mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image -A ==> set architecture to 'arch' -O ==> set operating system to 'os' -T ==> set image type to 'type' -C ==> set compression type 'comp' -a ==> set load address to 'addr' (hex) -e ==> set entry point to 'ep' (hex) -n ==> set image name to 'name' -d ==> use image data from 'datafile' -x ==> set XIP (execute in place) ./mkimage [-D dtc_options] -f fit-image.its fit-image 如何使用啊

mkimage制作zImage.img下载启动Linux 1.生成zImage.img [root@localhost tftpboot]# ls uImage zImage [root@localhost tftpboot]# mkimage -n 'linux-2.6.32.2' -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008000 -d zImage zImage.img Image Name: linux-2.6.32.2 Created: Thu Jan 22 16:36:52 2015 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 2286756 Bytes = 2233.16 kB = 2.18 MB Load Address: 30008000 Entry Point: 30008000 [root@localhost tftpboot]# ls uImage zImage zImage.img ( 介绍使用mkimage生成镜像文件并下载运行的方法。 1、首先，用u-boot/tools/mkimage这个工具为你的内核加上u-boot引导所需要的文件头，具体做法如下： [root@localhost tftpboot]#mkimage -n 'linux-2.6.14' -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008000 -d zImage zImage.img Image Name: linux-2.6.14 Created: Fri Jan 12 17:14:50 2007 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 1262504 Bytes = 1232.91 kB = 1.20 MB Load Address: 0x30008000 Entry Point: 0x30008000 这里解释一下参数的意义： -A ==> set architecture to 'arch' -O ==> set operating system to 'os' -T ==> set image type to 'type' -C ==> set compression type 'comp' -a ==> set load address to 'addr' (hex) -e ==> set entry point to 'ep' (hex) -n ==> set image name to 'name' -d ==> use image data from 'datafile' -x ==> set XIP (execute in place) ) 2.下载运行zImage.img U-Boot 2009.11 (04 2010 - 12:09:25) modified by tekkamanninja ([e-mail]) Love Linux forever!!
