# 建立esp32 debugger開發環境

## 購買ESP-PROG硬體
[購買鏈結](https://www.mouser.tw/ProductDetail/Espressif-Systems/ESP-PROG?qs=0lSvoLzn4L9lCAjJ8r9cdg%3D%3D)

## ESP-PROG和ESP32-WROOM模組接線

| ESP32 WROOM | Column 2 |
| -------- | -------- |
| GPIO12 | TDI |
| GPIO13 | TCK |
| GPIO14 | TMS |
| GPIO15 | TDO |
| GND | GND |

## 安裝RS232 driver
1. 使用zadig安裝。操作步驟如下:
1.1. 按下選單"Options->List All Devices"
2.1. 選擇DualRS232-HS(Interface 0)
1.3 然後就會看到ESP32、FT2232H和FT2232 JTAG的驅動

## 在範例專案blink裡面使用Openocd
為了使用Openocd修正launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "ESP32 OpenOCD",
      "type": "cppdbg",
      "request": "launch",
      "cwd": "${workspaceFolder}/build",
      "program": "${workspaceFolder}/build/blink.elf",
      "miDebuggerPath": "${command:espIdf.getXtensaGdb}",
      "setupCommands": [
        { "text": "target remote :3333" },
        { "text": "set remote hardware-watchpoint-limit 2"},
        { "text": "mon reset halt" },
        { "text": "thb app_main" },
        { "text": "flushregs" }
      ],
      "externalConsole": false,
      "logging": {
        "engineLogging": true
      }
    }
  ]
}

先在esp idf terminal用以下指令開啟Openocd server

openocd -f board/esp32-wrover-kit-3.3v.cfg

之後再visual studio codee按下Run and Debug
如果失敗可以多試幾次，成功後的畫面最終畫面如下:

## 使用ESP-PROG燒錄 ESP32
之後待做
