這下更慘了! 找不到元件的話連燒錄都會有問題。

建議檢查 ICSP 的接線? 減持一下 MCLR 腳除了有階提升電阻 10K 外是否也接電容到地? 如有接電容請移除後再試看看。

WDT off, OSC 設成IRCIO67, or IRCIO7
都顯示同樣的訊息


試過另一片板子顯示

Target Device ID (0x0) is an Invalid Device ID. Please check your connections to the Targe

MCU PIC18F2685是否這棵較不容易連PICKIT4?
有照data sheet建議調整MCLR pull up，試過33K, 10K

是否有其他建議?

"The target device is not ready for debugging" 通常是震盪器沒有震盪，PIC 沒有 Fosc 的驅動所以程式就無法執行。

建議在解決 HSPLL 外部震盪器之前先將震盪器的設定設成內部 RC 8MHz 先看看程式是否可以執行?

另一個設定就是在 Debug Mode 下，Watch-Dog Timer 一定要暫時先關閉，以避免系統又重置導致錯誤。
