Debug enable error CCS Compiler 5.073 with MPLAB X IDE v3.55
Posted: Sat Nov 04, 2017 6:10 pm
I have been using CCS Compiler with MPLAB IDE v8.92 and ICD3 to debug PIC code for years. Recently, I moved to PIC18F47K40 to get more code memory. Unfortunately, IDE v8.92 does not support 18F47K40. So I have to install MPLAB X IDE v3.55 in a Win7 32bit system. CCS Compiler v5.073 was also reinstalled with MPLAB IDE X Plug-in.
MPLAB X IPE was automatically installed with MPLAB X IDE. It works fine with my target board to program and erase the code in 18F47K40, which means the hardware setup with ICD3 is working properly.
But I couldn't get the debug mode working in CCS Compiler environment. When enabling the debug mode, I got a error message "Unable to open device: File access denied". Then, CCS will hang there forever unless forcing to end the task in Win7.
Any idea about this error message ? Something is missing for MPLAB X IDE to work in CCS environment for debug mode.
