从网盘中拷贝JpegPlayer文件至Ubuntu,并解压。然后将修改好的屏参和对应分辨率的图片拷贝到JpegPlayer目录下,并重命名为logo.jpg

  • 修改sstardisp.c文件内容
# vi sstardisp.c

  • 执行make,生成logo执行文件

  • 用U盘将JpegPlayer中的lib、logo、logo.jpg这三个文件拷贝到开发板中

  • 4G切换为usb模式,并挂载U盘
# echo UDISK > /dev/udisk_4g
# mount -t vfat /dev/sda1 /mnt
  • 配置环境
# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/lib
  • 执行logo
# cd /mnt
# ./logo  //注意:要在logo路径下执行,否则读取不到图片

成功显示
