近期有部分客户询问飞凌嵌入式i.MX8M系列开发板如何添加或更改开机动画,下文以OKMX8MM-C为例整理出如下思路,可供客户尝试。
一、下载 psplash源码
1.下载psplash:gitclone git://git.yoctoproject.org/psplash,会下载到当前目录的psplash文件夹中forlinx@ubuntu:~$ git clone git://git.yoctoproject.org/psplash
Cloning into 'psplash'...
remote: Enumerating objects: 11, done.
remote: Counting objects: 100% (11/11), done.
remote: Compressing objects: 100% (11/11), done.
remote: Total 306 (delta 2), reused 0 (delta 0), pack-reused 295
Receiving objects: 100% (306/306), 128.73 KiB | 74.00 KiB/s, done.
Resolving deltas: 100% (192/192), done.
注:代码可左右滑动,下同
2.下载成功后会在当前目录下生成一个psplash文件夹,进入psplash文件夹
forlinx@ubuntu:~$ cd psplash/
forlinx@ubuntu:~/psplash$ ls
forlinx@ubuntu:~/psplash$ sudo apt-get install libgdk-pixbuf2.0-dev
[sudo] password for forlinx:

Use 'sudo apt autoremove' to remove it.
【…】
forlinx@ubuntu:~/psplash$ sudo apt-get install build-essential libncurses5-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
【…】
4.将想要替换的图片复制到psplash文件夹中,此处用的是我们公司的logo,命名为logo-1024x600.png,外框照片命名为logo-bar.png。
进度条的外框logo-bar.png。将这两张图片拷贝到psplash源码目录中,如下图所示。
二、制作logo
1.在psplash源码中执行以下指令来生成logo-1024x600-img.hforlinx@ubuntu:~/psplash$ ./make-image-header.sh logo-1024x600.png POKY
forlinx@ubuntu:~/psplash$ ls
POKY参数只是一个变量,它会传入到logo-1024x600-img.h文件里面,可以打开查看。
forlinx@ubuntu:~/psplash$ vi logo-1024x600-img.h
forlinx@ubuntu:~/psplash$ ./make-image-header.sh logo-bar.png BAR
forlinx@ubuntu:~/psplash$ ls
forlinx@ubuntu:~/psplash$ vi logo-bar-img.h
3.打开psplash.c,将里面的#include"psplash-poky-img.h" 修改成#include"logo-1024x600-img.h"。将里面的#include" psplash-bar-img.h" 修改成#include"logo-bar-img.h"。修改完后如下图所示。
forlinx@ubuntu:~/psplash$ vi psplash.c
forlinx@ubuntu:~/psplash$ vi autogen.sh
内容如下:
#!/bin/bash
aclocal
autoheader
automake --add-missing
autoconf
制作完脚本后,赋予它可执行权限,再执行这个脚本。
forlinx@ubuntu:~/psplash$ chmod 777 autogen.sh
forlinx@ubuntu:~/psplash$ ./autogen.sh
configure.ac:7: installing './compile'
configure.ac:3: installing './install-sh'
configure.ac:3: installing './missing'
Makefile.am: installing './INSTALL'
Makefile.am: installing './depcomp'
5.修改Makefile.am,将psplash-poky-img.h修改成logo-1024x600-img.h,将psplash-bar-img.h修改成logo-bar-img.h。
forlinx@ubuntu:~/psplash$ vi Makefile.am
修改完后的Makefile.am如下图所示。
修改完Makefile.am后保存退出,回到源码目录下。6.执行以下指令,使能环境变量。forlinx@ubuntu:~/psplash$ . /opt/fsl-imx-xwayland/4.14-sumo/environment-setup-aarch64-poky-linux
7.环境变量使能后,就可以执行以下指令配置交叉编译工具链。
forlinx@ubuntu:~/psplash$ ./configure --host=aarch64-poky-linux
configure: loading site script /opt/fsl-imx-xwayland/4.14-sumo/site-config-aarch64-poky-linux
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for aarch64-poky-linux-strip... aarch64-poky-linux-strip
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... no
checking for mawk... mawk
checking whether make sets $(MAKE)... yes
checking whether make supports nested variables... yes
checking for style of include used by make... GNU
【…】
8.执行make指令进行编译。
forlinx@ubuntu:~/psplash$ make
cd . && /bin/bash /home/forlinx/psplash/missing automake-1.15 --gnu Makefile
cd . && /bin/bash ./config.status Makefile depfiles
config.status: creating Makefile
config.status: executing depfiles commands
./make-image-header.sh base-images/psplash-bar.png BAR
make all-am
make[1]: Entering directory '/home/forlinx/psplash'
aarch64-poky-linux-gcc
--sysroot=/opt/fsl-imx-xwayland/
4.14-sumo/sysroots/aarch64-poky-linux -DHAVE_CONFIG_H -I
. -g -Wall -Wextra
-D_GNU_SOURCE -DFONT_HEADER=\"radeon-font.h\"
-DFONT_DEF=radeon_font -O2 -pipe -g
-feliminate-unused-debug-types
-MT psplash-psplash.o -MD -MP -MF
.deps/psplash-psplash.Tpo -c -o psplash-psplash.o
`test -f 'psplash.c' || echo './'`psplash.c
【…】
编译完成后会在源码目录下生成psplash和psplash-write文件。
三、替换出厂系统logo
将编译生成的psplash和psplash-write文件拷贝到开发板出厂文件系统/usr/bin目录下。okmx8mm login:root
Last login: Thu Jun 20 10:00:15 UTC 2019 on tty7
root@okmx8mm:~# cd /usr/bin/
root@okmx8mm:/usr/bin# ls psp*
psplash psplash-default psplash-write
root@okmx8mm:/usr/bin# rm psplash
root@okmx8mm:/usr/bin# rm psplash-write
root@okmx8mm:/usr/bin# cp /run/media/sda1/psplash ./
root@okmx8mm:/usr/bin# cp /run/media/sda1/psplash-write ./
root@okmx8mm:/usr/bin# sync
注意:目前我们的OKMX8MM-C做了开机连续显示,所以默认没有开机动画,若客户有需要可按上述方式进行添加。同时此方法在OKMX8MQ-C和OKMX8MP-C上也同样适用。
