T-Head Debugger Server 连线问题

[brissett]

我的 CKLink_Lite_V2 接到 Sparkfun SDcard sniffer pinout 再接到板子, 想用 GDB 调试板子

DebugServer 从 T-Head 页面下载的 T-Head-DebugServer-linux-x86_64-V5.16.2-20220708.sh.tar.gz

想问

1. VCC 应该是接到 CKLink 的 Vref?
2. 因为 Jtag 与 SD 卡共用脚位，Sparkfin SDcard sniffer 上是否不能放 SD card 呢？

错误信息：

@brissett VCC可以不用连接（我反正没连
可以试试按住FEL连接CKLink

@yuzukitsuru
谢谢回覆
想请问DebugServer 是要搭配 xfel 一起使用吗？
线路都接起来后，我的操作方式： xfel 按钮 -> 板子上电 -> CKLINK 上电 -> xfel ddr ddr3（console 有正常反应）-> xfel jtag (console 没反应) -> DebugServer -arch riscv --debug connect (console 印出一样的错误信息)

奇怪的是我两张 Nezha 板子都有 Read DTM IDCODE get 0xffffffff, it isn't T-HEAD implementation.

不知道我的操作流程是否有误？

@brissett 不需要xfel吧，我记得上电就行了
