打開 OCD 錯誤：libusb_open() 因 STM32 的 Windows 10 上的 LIBUSB_ERROR_ACCESS 而失敗

Question

我正在嘗試在 Windows 10 上使用 Visual Studio Code 和 OpenOCD 將 flash 代碼轉換為 STM32F030R8T6。我還使用 STM32CubeMX 自動生成開始代碼並使用 stlink v2。 電腦可以看到stlink，我就可以成功連接STM32F030R8T6了。

我不斷遇到一個問題，我可以很好地構建項目，但是我永遠無法完成 flash。

這是使用 STM32CubeMX 制作的 make 文件，我添加的唯一部分是 flash 組件。

在執行 flash 命令（制作閃存）時，我遇到了以下錯誤。

openocd -f interface/stlink.cfg -f target/stm32f0x.cfg -c "program build/VSCodeTest.elf verify reset exit"

我已經看到 linux 解決了這個問題，但我找不到 windows。

希望你現在已經解決了。 我相信這是多個命令的序列。 嘗試

openocd -f interface/stlink.cfg -f target/stm32f0x.cfg -c init -c "program $(BUILD_DIR)/$(TARGET).elf verify" -c reset -c exit
