This article will explain in detail about the use of linux's mkimage command to make bootable image files. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The mkimage tool is a tool used by u-boot to make image files, and its source code is in the tools directory of the u-boot source code: mkimage.c. We use this tool to add a header to both the kernel and the root file system that we load with the bootm command.

Syntax format: mkimage [parameters]

Common parameters:

Reference example

Add the header required for u-boot boot to the kernel:

[root@linuxcool] # mkimage-n 'linux-2.6.14'-An arm-O linux- T kernel-C none-a 0x30008000-e 0x30008000-d zImage zImage.img

Specify the CPU architecture and operating system:

[root@linuxcool] # mkimage-An arm-O linux-a 0x20008000-e 0x20008000-d linux.bin.gz uImage

Specify the compression format:

[root@linuxcool] # mkimage-An arm-O linux-C bzip2-a 0x20008000-e 0x20008000-d linux.bin.gz uImage about using linux's mkimage command to create bootable image files is shared here.
