[PIC] proteus simulation error "eeprom data has invalid address[2000]"

[OK.ME]

MY proteus simulation shows error for pic16f877a for the 7 sement 4 digit led display counter. my code is


#pragma config FOSC = EXTRC // Oscillator Selection bits (RC oscillator)
#pragma config WDTE = ON // Watchdog Timer Enable bit (WDT enabled)
#pragma config PWRTE = OFF // Power-up Timer Enable bit (PWRT disabled)
#pragma config BOREN = ON // Brown-out Reset Enable bit (BOR enabled)
#pragma config LVP = ON // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3/PGM pin has PGM function; low-voltage programming enabled)
#pragma config CPD = OFF // Data EEPROM Memory Code Protection bit (Data EEPROM code protection off)
#pragma config WRT = OFF // Flash Program Memory Write Enable bits (Write protection off; all program memory may be written to by EECON control)
#pragma config CP = OFF // Flash Program Memory Code Protection bit (Code protection off)

// #pragma config statements should precede project file includes.

}}
}}


there is no any compilation error in mplab but in proteus segment display is shwing as expected and there is error showing "eeprom data has invalid address[2000]".

please help anyone i need to submit my clg project by tmrw.

I don't have Proteus but there is no mention of EEPROM in the code so I would guess you have a configuration error in Proteus itself and the code is good.

I think there are two input sections for micrcontroller programming in proteus. One is for input hex of normalFlashROM and other is for hex of eeprom data.

Probably you are uploading compiled hex in eeprom input section in proteus instead of normal Program hex. Can you show us proteus config screen.
