Hi to all,
I am running MPLAB software to a PIC16F877A microcontroller via a CCS ICD-S20 pod. After downloading the code I get a pop-up with the following error message:
"Could not start the target. The target was not halted after reset. Check the target oscillator and MCLR."
I am using a 20MHz crystal oscillator from EPSON (working fine). The MCLR circuit is an MCP120-4.5V pulled up to 5V with 4.7K, diode-isolated with a BAT54 diode, pulled down to GND with 47K, then connected to MCLR and the ISP connector. PGB, PGC, and PGM are connected only to the ISP connector.
The code actually downloads and runs but I can't breakpoint.
Any inputs are most welcome, Ray
