安装和配置烧录工具

安装烧录工具

　　打开工具目录，双击CW_ARMv8_v2019.01_b190130_Win_Offline.exe进行安装，安装路径和配置默认选择。

复制rcw和uboot镜像到烧录工具目录

　　复制rcw_800.bin.swapped和ls1012a-ek200-uboot.bin到目录C:\Freescale\CW4NET_v2019.01\CW_ARMv8\ARMv8\gdb\bin。

配置烧录工具脚本文件

　　1.打开文件C:\Freescale\CW4NET_v2019.01\CW_ARMv8\ARMv8\gdb_extensions\flash\cwflash.py
　　2.修改文件中的内容： 。。。
PROBE_CONNECTION = "cmsisdap"
。。。
FLASH_TYPE = "qspi"
。。。
SOC_NAME = "LS1012A"
。。。
JTAG_SPEED = 6000
。。。


开发板烧录rcw和uboot镜像

使开发板处于下载模式

　　找到开发板上的 BOOTMODE 或 BOOT SWITCH 所指示的二位拨码开关，1拨到ON，2拨到OFF。

连接开发板和电脑

　　1. 打开电源，插上K20-JTAG模块到开发板，另外一端连接通过MINI USB线连接到电脑。
