[kylin M900]麒麟操作系统固件修改与合成

news 来源：原创 2024/9/20 4:41:38

1.解压ISO

2.修改文件系统

3.生成新的ISO

3.1使用PowerISO软件生成ISO

3.2使用Linux脚本生成ISO

4.制作启动盘

4.1使用UltraISO软件制作启动盘

4.2使用Linux脚本制作启动盘

5.安装系统

1.解压ISO

前段时间做的一个项目，用的soc是海思的M900，系统使用麒麟系统，因麒麟系统不开源，只能使用其公开的固件，我在该固件上负责修改、解决bug、增加功能，最后合成新固件。麒麟系统的固件为iso格式：Kylin-Desktop-V10-SP1-2303-update3-Wayland-Release-M900-20240130-arm64.iso。解压后的文件如下图所示：

在casper文件夹下存放着麒麟系统的文件系统文件filesystem.squashfs，如下图所示。

想要修改文件系统的内容，将filesystem.squashfs提取出来解压后修改再压缩即可。解压和压缩的命令如下所示。

解压 filesystem.squashfsunsquashfs filesystem.squashfs压缩 filesystem成filesystem.squashfsmksquashfs filesystem filesystem.squashfs

2.修改文件系统

为了能让系统开机后自动执行一些命令，在root用户下执行“crontab -e”，将会生成文件：/var/spool/cron/crontabs/root，这个文件可以开机自动执行一些脚本命令或定时执行一定的任务。如：* * * * * date >> /home/log 每分钟执行一次。

crontab -e命令生成的/var/spool/cron/crontabs/root文件如下所示。

# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.bMsRWr/crontab installed on Wed Apr  3 15:33:54 2024)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
# Edit this file to introduce tasks to be run by cron.
# 
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
# 
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').
# 
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
# 
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
# 
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
# 
# For more information see the manual pages of crontab(5) and cron(8)
# 
# m h  dom mon dow   command

在/usr/local/bin/放置文件，如下所示。

8852bs.ko cfg80211.ko preinstall.sh biometric-driver-microarray-yukifinger_4.0.0-0-g88ffd86_arm64.deb

preinstall.sh脚本如下所示，该脚本会写到/var/spool/cron/crontabs/root文件里面，这样系统每次开机后就会执行preinstall.sh。

#!/bin/bashsetsignstatus  offif [ ! -e "/usr/local/bin/first_reboot_flag" ];
thensudo sh -c 'dpkg -i --force-overwrite /usr/local/bin/biometric-driver-microarray-yukifinger_4.0.0-0-g88ffd86_arm64.deb' >> /usr/local/bin/log
fitouch /usr/local/bin/first_reboot_flagsudo setstatus softmode -p#47wifi
sudo insmod /usr/local/bin/cfg80211.ko
sudo insmod /usr/local/bin/8852bs.kosetsignstatus warning

我的项目最终的 preinstall.sh脚本如下所示。

#!/bin/bashdate >> /usr/local/bin/log

执行脚本的文件root，将其复制到/var/spool/cron/crontabs/

# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.bMsRWr/crontab installed on Wed Apr  3 15:33:54 2024)

sudoers文件配置使用sudo时不用密码，将sudoers复制到/etc下,这样执行preinstall.sh脚本就不用输入密码了

将 %sudo ALL=(ALL:ALL) ALL

改成 %sudo ALL=(ALL:ALL) NOPASSWD:ALL

修改后的sudoers文件如下所示。

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#

文件系统修改完毕，使用“mksquashfs filesystem filesystem.squashfs”命令压缩文件系统，脚本mkfilesystem.sh 如下所示。

#!/bin/bashrm filesystem.squashfs
mksquashfs squashfs-root filesystem.squashfs

3.生成新的ISO

3.1使用PowerISO软件生成ISO

widows下打开PowerISO软件，并打开Kylin-Desktop-V10-SP1-2303-update3-Wayland-Release-M900-20240130-arm64.iso，如下图所示。

将filesystem.squashfs替换再保存即可生成新的系统固件，如下图所示。

3.2使用Linux脚本生成ISO

使用命令来生成ISO，脚本mkiso.sh如下所示。

#!/bin/bashrm -r out
mkdir out
mkdir -p out/iso_mount
mkdir -p out/iso_filesudo mount -o loop Kylin-Desktop-V10-SP1-2303-update3-Wayland-Release-M900-20240130-arm64.iso out/iso_mount
cp -r out/iso_mount/ out/iso_file
sudo umount out/iso_mount
rm out/iso_file/iso_mount/casper/filesystem.squashfs
cp filesystem.squashfs out/iso_file/iso_mount/casper/filesystem.squashfssudo mkisofs -r -o out/new_modified_iso.iso out/iso_file/iso_mount/
