W800 基础版开发板 CKLINK 调试-连接 CKLINK 后不能识别

今天测试 W800 基础版开发板 CKLINK 调试, 内置的是涂鸦云 SDK.
开发板状态正常, LOG 信息:

开发板状态应该是正常的.
但按教程连接后, CDK 提示错误:
[ERROR]Fail to check had module of CPU 0, please check:

1.  the physical connection; 
2.  the power of the target; 
3.  the link clock  (link clock  =  (CPU clock/2) ) ; 
4.  the reference voltage of link,  default 3. 3v; 

For more information, please run Debugserver with connect log:

 Console:  run Debugserver with arguments "--debug connect". 
 UI     :  select "Connect" from menu "Setting- Verbose Setting". 

T-HEAD CKLINK:

          ICE Type:  CKLink_Lite_V2
          App Ver :  2. 35
          Bit Ver :  null
          ICE Clk :  2526. 316KHz

5-wire, With DDC, Cache Flush OnSN CKLink_Lite_V2-65D70308D6.
Extra Info: hacr width is 8.
测量了 W800 开发板上 3v3 和 GND 电压, 3. 264v, 应该属于正常范围.
有没有大神实际用过 W800 基础版+cklink 的调试, 帮忙看看? 已复位 N 次, 换了杜邦线, 重插了连接线, 还是不行
