centos 8如何安装uboot工具

Question

我想在我的 Centos 8 中使用命令 mkimage。

我尝试使用命令 dnf install uboot-tools 以 root 身份安装 uboot-tools，但这不可用。

谁能指导我如何在我的系统上安装 uboot-tools？

Answer 1

我建议从头开始构建 u-boot 工具，这不会花很长时间：

wget https://github.com/u-boot/u-boot/archive/v2020.07.tar.gz
tar zxf v2020.07.tar.gz
make  -C u-boot-2020.07 mrproper qemu-x86_64_defconfig tools

mkimage 将在此处提供：u-boot-2020.07/tools/mkimage。

ls -gG u-boot-2020.07/tools/mkimage
-rwxrwxr-x 1 240152 Sep 22 08:13 u-boot-2020.07/tools/mkimage

u-boot-2020.07/tools/mkimage 
Error: Missing output filename
Usage: u-boot-2020.07/tools/mkimage -l image
          -l ==> list image header information
       u-boot-2020.07/tools/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)
       u-boot-2020.07/tools/mkimage [-D dtc_options] [-f fit-image.its|-f auto|-F] [-b <dtb> [-b <dtb>]] [-i <ramdisk.cpio.gz>] fit-image
           <dtb> file is used with -f auto, it may occur multiple times.
          -D => set all options for device tree compiler
          -f => input filename for FIT source
          -i => input filename for ramdisk file
Signing / verified boot not supported (CONFIG_FIT_SIGNATURE undefined)
       u-boot-2020.07/tools/mkimage -V ==> print version information and exit
Use '-T list' to see a list of available image types

你现在可以将它移动到/usr/local/bin：

sudo cp u-boot-2020.07/tools/mkimage /usr/local/bin
