更新FPGA配置程序：点击下载

请连接至开发板并新建一个sh文件，内容如下

#!/bin/sh
if [ -f "soc_system.rbf" ];then
	  if [ -f "soc_system.dtb" ];then
       clear
       echo ----------------------------------------------------------------------------------
       echo INFO: This program was developed by ChanRa1n and all rights reserved.
      umount /soctemp
      rm -rf /soctemp
      mkdir /soctemp
      mount /dev/mmcblk0p1 /soctemp
      echo INFO: disk mount success!
      cp soc_system.rbf /soctemp/soc_system.rbf
      cp soc_system.dtb /soctemp/soc_system.dtb
      sleep 3s
      echo INFO: soc data copy success!
      /soctemp/hps_config_fpga /soctemp/soc_system.rbf
      sleep 3s
      umount /soctemp
      echo INFO: disk umount success!
      rm -rf /soctemp
      echo INFO: clean temp file success!
      echo INFO: soc flash finished!
      echo If an error occurs in the process, please restart the development board manually!
      echo ----------------------------------------------------------------------------------
    else
      echo ERROR: soc_system.dtb not exists!
    fi
else
    echo ERROR: soc_system.rbf not exists!
fi

接下来，请将dtb文件和rbf文件放置和sh文件同一级目录，并运行以下命令：

chmod +x flashsoc.sh && sh ./flashsoc.sh

运行示例：

----------------------------------------------------------------------------------
INFO: This program was developed by ChanRa1n and all rights reserved.
INFO: disk mount success!
INFO: soc data copy success!
INFO: alt_fpga_control_enable().
INFO: alt_fpga_control_enable OK.
alt_fpga_control_enable OK  next config the fpga
INFO: MSEL configured correctly for FPGA image.
/soctemp/soc_system.rbf file file open success
INFO: FPGA Image binary at 0xb2c64008.
INFO: FPGA Image size is 2068700 bytes.
ERROR: FPGA failed to program after 5 attempt(s).
INFO: alt_fpga_control_disable().
INFO: disk umount success!
INFO: clean temp file success!
INFO: soc flash finished!
If an error occurs in the process, please restart the development board manually!
----------------------------------------------------------------------------------

如果如图所示，出现了ERROR，请重启开发板。(断开开发板电源，并重新上电，或者ssh输入reboot也可以)

如果没有出现ERROR，例如

INFO: alt_fpga_control_enable().
alt_fpga_control_enable OK  next config the fpga
INFO: MSEL configured correctly for FPGA image, MSELs ==a.
C5MB_top.rbf file file open success
INFO: FPGA Image binary at 0xb2bd3008.
INFO: FPGA Image size is 2058776 bytes.
INFO: alt_fpga_configure() successful on the 1 of 5 retry(s).
INFO: alt_fpga_control_disable().

则在线配置成功完成！FPGA端的配置已经更新。

如果你只需要对FPGA重新配置，则只需要运行

./hps_config_fpga soc_system.rbf
