What is this warning ICD0161 about?(on programming PIC) - Electronic Circuits Projects Diagrams Free

Problems as below:

Code:

Connecting to MPLAB ICD 2
...Connected
Setting Vdd source to MPLAB ICD 2
Target Device PIC12F629 found, revision = Rev 0x10
...Reading ICD Product ID
Running ICD Self Test
...Passed

...Program Memory
ICD0161: Verify failed (MemType = Program, Address = 0x0, Expected Val = 0x1283, Val Read = 0x3FFF)
ICD0275:  Programming failed.
MPLAB ICD 2 Ready

Code:

ICDWarn0044:  Target has an invalid calibration memory value (0x3FFF).  Continue?

I found this warning and unable to program my PIC using MPLAB ICD2 ,

ICD0161: Verify failed (MemType = Program, Address = 0x0, Expected Val = 0x1283, Val Read = 0x3FFF)
ICDWarn0044: Target has an invalid calibration memory value (0x3FFF). Continue? ( i already programmed 1 of my same pic (succeeded), this is the 2nd 1, what's wrong with it?)
What is it about?

Thanks...

That is the calibration for the internal RC oscillator. Unless you are using that oscillator and you need its full accuracy, you can ignore that warning.

sadly yes... i m using the internal OSC, i think i already configured the setting correctly.
why am i encounter this problem everytime i try to connect the ICD2?
its works fine for 1 time...and 1 chip was successfully configured.

Post the CONFIG lines of your program.

Hi, config line as below,

Code:

 __CONFIG   	_CP_OFF & _MCLRE_OFF & _WDT_OFF & _INTRC_OSC_NOCLKOUT & _BODEN_OFF & _CPD_OFF &_PWRTE_OFF

Thanks!

Use MLCRE_ON and see what happens
