我在 Windows 机器上使用 ESP-Prog。
我在面包板上使用连接到 HUZZA32 Feather 的 ESP-Prog。
信号：ESP-PROG -> HUZZA32
MTCK：4 - MTCK -> 13 - MTCK
MTDI：8 - TDI -> 12 - MTDI
MTDO：6 - TDO -> 15 - MTDO
MTMS：2 - TMS -> 14 - MTMS
3V： 1 - VJTAG -> 3.3V
GND：3 - GND -> GND
我修改了 JTAG 驱动程序以使用 WinUSB。
我正在使用在 github
https://github.com/espressif/openocd-es ... 2-20221026上找到的 OpenOCD ESP32 v0.11.0 版本。
以下是我用来刷机的步骤：
代码：
全选
cd C:openocd-esp32-win32-0.11.0-esp32-20220706openocd-esp32in
openocd.exe -f ..shareopenocdscriptsoardesp32-wrover-kit-3.3v.cfg -c "program_esp file.bin 0x10000 verify exit"
这是我得到的回应。

我已经以各种方式尝试过很多次了。有一次它几乎成功了，但我从未成功进行过 JTAG 扫描或文件上传。
这里有什么问题？
