无法在 Mac 上安装和配置 J-Link JTAG 调试器
Unable to install and configure a J-Link JTAG debugger on a Mac
我有一个 Segger J-Link，我想在 Macbook 运行ning MacOS Catalina 10.15.4 上使用它，使用 openocd 和 GDB 针对 ESP32 开发板。问题是我看不到设备：
$ ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port /dev/cu.JimsiPhone-WirelessiAP /dev/cu.SLAB_USBtoUART /dev/cu.usbserial-0001
None 其中是 J-Link。如果我 运行 lsusb 我可以看到它：
$ lsusb
Bus 020 Device 002: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 020 Device 003: ID 1366:0101 SEGGER J-Link ARM
我已经安装了从 Segger 下载的 "J-Link Software and Documentation Pack"。我已经检查了 Mac "Security and privacy" 设置，它没有报告它阻止安装任何驱动程序或程序或 运行.
在 J-Link 上，绿色 LED 亮起，每秒闪烁两次。
我确定我少了一块，非常感谢您的帮助。
更新：我一直在按照此处的说明进行操作：
在我进入第 6 步之前一切正常，我按照以下说明操作：
问题是，驱动程序的路径从未出现，正如我上面所描述的。如果我不能让它与我的 J-link.
对话，我认为我无法 运行 OpenOCD
当我 运行 openocd-esp32 时，我得到（来自 openocd-esp32 输出的完整粘贴如下）：
Error: No J-Link device found.
esp32-wroom-32.cfg的内容是：
echo "WARNING: boards/esp-wroom-32.cfg is deprecated, and may be removed in a future release."
set ESP32_FLASH_VOLTAGE 3.3
source [find target/esp32.cfg]
这是完整的粘贴：

运行 JLinkExe 确实找到了 J-Link:

完成上述操作后，我现在在 运行ning openocd-esp32 时收到不同的错误消息（可能是因为 J-Link FW 升级？）。最初它抱怨没有设置适配器速度，所以我修改了 interface/jlink.cfg 并添加：
adapter_khz 3000
我现在得到一个不同的错误：
Error: JTAG scan chain interrogation failed: all ones
我一直在谷歌搜索，这可能意味着电路板损坏或另一个配置问题。虽然ESP32-WROVER-32U上面有SPI flash，但是SD卡槽里没有SD卡，板子上也没有其他SPI设备。

我建议逐步验证您的设置 - 我个人不喜欢大爆炸式集成。
- 验证您的 Segger 软件是否可以看到您的 JLink 探针 - 好消息是
lsusb 可以看到它。 JLink Commander 应该会提供一些有用的信息。
- 在没有任何可执行文件相关参数的情况下启动 openocd：
openocd -f interface/jlink.cfg -f board/esp-wroom-32.cfg
- 验证基本命令是否正常工作，即重置 CPU、显示寄存器、reading/writing 内存。
- 如果您仍在试验问题，请仔细检查您的接线 - 有关详细信息，请参阅 here。
