我现在将Avdd和Avss分别接5V和地,但测量到5V与地间的电阻只有30~40欧姆,这是怎么回事呢?Avdd与Avss悬空时,它们间的电阻有700~800欧姆,是不是CPU被烧坏了?

是否忘了將 Avdd & Avss 與 Vdd & Vss 接在一起給電。

I want to use ICD2 to debug my target board with pic18f6680,ICD2 can identify my board's cpu as PIC18F6680,and I wrote a simple program just to light some leds,and compiled successfully,but when I want to program the board by ICD2,output window display the following messages:
.......... Programming Target... ...Programming Program Memory (0x0 - 0xD1F) ...Loading DebugExecutive ...Programming DebugExecutive ...Programming Debug Vector ...Programming RSBUG Verifying... ...Program Memory ICD0161: Verify failed (MemType = Program, Address = 0x0, Expected Val = 0xEF0C, Val Read = 0xFFFF) ICD0275: Programming failed. MPLAB ICD 2 Ready I don't know where the problem is,the target board is powered by itself.
