Debugging Problem in MPLAB on CCS compiler

[harshanahnd]

Hi,

I was trying to debug a code that I have written for a 18F4550 PIC. I configured CCS Compiler on MPLAB. And I build the project that I have written successfully on MPLAB. No problems occurred when building the project.
But when I try to program it (Debugger => Program) following output comes,

MPLAB ICD 2 ready for next operation

ICD0083: Debug: Unable to enter debug mode. Please double click this message for more information.

I am unable to find out what is the problem in here. Oscillator frequency is set correctly. Are there any other configuration bits to be set?
Please help me.
Thanks.

Hi,

Thanks for your help. I was able to solve the problem by setting the ICD/ICSP configuration bit to Disabled.

Hi all,

I need to test my source code on the MPLAB in circuit debugger. But it gives following errors as the output. If someone could help me on this matters, it would be very helpful to me.

Thanks a lot.
