  luckfox-config 设置UART，在重启后luckfox.cfg的RX和TX配置会调换，是否正常。
  -- 刚配置好UART，未重启
  root@luckfox:/home/edu_control# cat /etc/luckfox.cfg
  TP_STATUS=1
  I2C2_STATUS=1
  I2C2_SCL_RM_IO=1
  I2C2_SDA_RM_IO=0
  UART3_STATUS=1
  UART3_RX_RM_IO=4
  UART3_TX_RM_IO=3
  -- 重启后
  root@luckfox:/home/edu_control# reboot
  root@luckfox:/home/edu_control#
  c:\adb_fastboot>adb shell
  root@luckfox:/# cat /etc/luckfox.cfg
  TP_STATUS=1
  I2C2_STATUS=1
  I2C2_SCL_RM_IO=1
  I2C2_SDA_RM_IO=0
  UART3_STATUS=1
  UART3_RX_RM_IO=3
  UART3_TX_RM_IO=4
