USB 口插錯。Petros CH32H417M Alef 是 Pico 尺寸板，核心是 WCH CH32H417M MCU，並提供兩組 20-pin Pico 相容排針，以及 6-pin 的 SWD 與 UART6 除錯接頭。\u003C\u002Fp>\n\u003Cfigure class=\"my-6\">\u003Cimg

口、相機接頭與除錯排針的位置，不需要猜。\u003C\u002Fp>\u003Ch2>Step 2: 接上電源與主機 USB\u003C\u002Fh2>\u003Cp>目的：讓板子安全上電，先確認供電路徑穩定。這塊板可從 USB 3.0 口或排針吃 5V，板上有 3.3V\u002F1A LDO 供邏輯電路使用。\u003C\u002Fp>\n\u003Cfigure

需要的影像輸入鏈。Petros 板使用 40-pin B2B 接頭連接 2MP OV2640 模組，並以 DVP 作為主要相機資料路徑。\u003C\u002Fp>\u003Cp>把 Phos Ayin OV2640 模組對準後壓入，確認接頭完全咬合、沒有歪斜。這一步完成後，板子才算真正進入相機平台狀態，而不只是一般 MCU 開發板。\u003C\u002Fp>\u003Cp>驗收：你應該看到模組固定牢靠、沒有明顯晃動，手指輕碰時也不會鬆脫。\u003C\u002Fp>\u003Ch2>Step 4: 連接除錯器與序列埠\u003C\u002Fh2>\u003Cp>目的：先拿到燒錄與 log 存取權，再開始改韌體。這塊板沒有內建 Link-E 除錯器，所以 SWD 與 UART6 接頭就是主要開發入口。\u003C\u002Fp>\u003Cp>把 Amnos LinkE Alef 或相容除錯器接到 6-pin 接頭，分別對上 SWD 燒錄與 UART6 主控台輸出。線越短越好，接電前先核對 pin 順序與供電方向。\u003C\u002Fp>\u003Cp>驗收：你應該能從 IDE 或除錯工具連上目標 MCU，並在序列埠看到 UART6 輸出。\u003C\u002Fp>\u003Ch2>Step 5: 開啟 SDK 相機範例\u003C\u002Fh2>\u003Cp>目的：從已經支援 DVP 與 USB 3.0 的範例開始，減少從零寫韌體的風險。WCH CH32H417 開發 SDK 已含 DVP 與 USB 3.0 範例，MounRiver SDK 也可用來開專案。\u003C\u002Fp>\u003Cp>先取得官方文件與 SDK，再找出結合 USB SuperSpeed 與 DVP 擷取的 sample，然後把板級設定改成 Petros 的接腳、時脈與相機初始化。官方開發資源可從 [WCH 官方網站](https:\u002F\u002Fwww.wch.cn\u002F) 與 [MounRiver Studio](https:\u002F\u002Fwww.mounriver.com\u002F)

相機枚舉\u003C\u002Fh2>\u003Cp>目的：確認板子在主機上真的像相機一樣工作。理想結果是 USB Video Class 裝置，而不是只出現一般 USB 周邊。\u003C\u002Fp>\u003Cp>先燒錄，再重新插拔板子，檢查主機裝置清單。若韌體正確，主機應該會看到 UVC 類型的相機裝置。社群資料也提到，這塊板在沒有相機模組時做過 USB 3.0 傳輸測試，結果可達 430 MB\u002Fs，這能當作你後續調校資料路徑的參考。\u003C\u002Fp>\u003Cp>驗收：你應該在主機上看到 UVC 相機項目，或至少看到可辨識的 USB SuperSpeed
