請教版主及各位大大有關"Invalid target device id "
我使用ICD2用於自己拉的電路板出現下列問題 請教版主及各位大大! 1 程式未燒錄時按MPLAB IDE上的連線ICD2按鈕 會連線成功沒有錯誤訊息，再多按幾次也是如此 2 接著燒路程式也能成功燒錄沒有錯誤訊息,且程式 可以RUN，step run 都沒問題 3 但我此時若在按一次燒錄按鈕則會失敗，再連線幾次每次 都會失敗 信息: Connecting to MPLAB ICD 2 ...Connected Setting Vdd source to target ICDWarn0020: Invalid target device id (expected=0x141, read=0x0) ...Reading ICD Product ID Running ICD Self Test ...Passed MPLAB ICD 2 Ready 4 若將Target Board 斷電再送電一次後則可正常連線，但第 二次連線就會出現錯誤，若再斷電一次則可再連一次! 5 若將 Device Earse 則又可正常連線 6 我的ICD2版本昰R23,插上買來的Demo Board (Device:dspic6010)一切正常，IDE版本是V7.42 7 出問題的Target Board Device:dspic4013, PGC,PGD 各 串一330歐姆接於ICD2。MCLR 接一10K提升電阻於 VDD:5V MCLR沒接電容。PGC PGD MCLR 只與ICD2連接 8 測試程式昰由 tmp6010.s 改來的，只將前兩行改成 .equ __30F4013, 1 .include "p30f4013.inc"
