CYW43907用jtag下载程序不成功怎么解决？

你好，我遇到一个问题，用jtag下载程序是不成功：
目前的状况是这样的，
使用的软硬件：
板子是根据手册自己画的，不是开发板。
软件使用WICED-Studio 6.2
仿真器使用Jlink-V9（驱动使用_V770，这个版本支持CYW43907器件，所以没有拷贝f flashloader_ CYW4390x文件到segger的安装目录下，也没有修改<>文件）
做过以下修改：

• 按照教程配置了Debug Configurations的相关设置。
  
• 在wiced_toolchain_common.mk中修改为JTAG=jlink。并在...toolsOpenOCDjlink.cfg中的最后加上“reset_config trst_and_srst srst_open_drain”。
  
• 在tools/OpenOCD/BCM4390x.cfg中用‘reset_config trst_and_srst srst_push_pull srst_nogate connect_assert_srst’代替‘reset_config srst_nogate connect_assert_srst’
  
• 把make target名称修改为snip.scan-CYW943907AEVAL1F-debug JTAG=jlink download run
  
• 用zadig-2.8.exe将jlink driver改为libusbk.现在下载时报错如下：11:35:08 **** Build of configuration Default for project 43xxx_Wi-Fi ****
  "E:\Users\Administrator\Documents\WICED-Studio-6.2\43xxx_Wi-Fi\make.exe" snip.scan-CYW943907AEVAL1F-debug JTAG=jlink download run
