I am trying to run a program on PIC18F4520 using PicKit3 & MPLAB IDE. But I am getting an error: PK3Err0040: The target device is not ready for debugging. Please check your configuration bit settings and program the device before proceeding.
Whereas when I try to run one of the old program, its running. My new program code which is not running is:
B4X:
#pragma config OSC = HS,FCMEN = OFF,IESO = OFF // CONFIG1H
#pragma config PWRT = OFF, BOREN = SBORDIS, BORV = 0 // CONFIG2L
#pragma config WDT= OFF, WDTPS = 32768 // CONFIG2H
#pragma config MCLRE = OFF, LPT1OSC = OFF, PBADEN = ON, CCP2MX = PORTC //CONFIG3H
#pragma config STVREN = ON, LVP = OFF, XINST = OFF // CONFIG4L
#pragma config CP0 = OFF, CP1 = OFF, CP2 = OFF, CP3 = OFF // CONFIG5L
#pragma config CPB = OFF, CPD = OFF // CONFIG5H
#pragma config WRT0 = OFF, WRT1 = OFF, WRT2 = OFF, WRT3 = OFF // CONFIG6L
#pragma config WRTB = OFF, WRTC = OFF, WRTD = OFF // CONFIG6H
#pragma config EBTR0 = OFF, EBTR1 = OFF, EBTR2 = OFF, EBTR3 = OFF // CONFIG7L
#pragma config EBTRB = ON // CONFIG7H
