我最近从 Linux 机器切换到装有 macOS Sierra 10.12.4 的 Macbook Pro 2016。

当我尝试连接到 J-Link 时,无论我使用哪个应用程序(JLinkExe 或 JLinkGDBServer)都失败,并出现以下错误:

kuba@chimera:~$ JLinkExe
SEGGER J-Link Commander V6.14c (Compiled Mar 31 2017 17:42:24)
DLL version V6.14c, compiled Mar 31 2017 17:42:10

Connecting to J-Link via USB...FAILED: Can not connect to J-Link via USB.
J-Link>

dmesg 中完全没有关于J-Link 的信息。我怀疑我的笔记本电脑中的 USB-C 端口可能存在一些问题。但是,我尝试了两种不同的适配器,但没有结果。在 Linux 上它确实工作得很好。

有什么想法吗?谢谢。

编辑:这是“ioreg -p IOUSB -l -w 0”的缩短输出:

最佳答案

我解决了。我的 J-Link 电缆中的 USB 连接器构造不当,有些东西没有按应有的方式连接。我尝试了不同的 USB 数据线,没问题。
