icd2 clone failed mplab icd 2 operation
Hello everybody,
First, thank everybody for making this greate project.
I have buildet the ICD2 clone with the PIC18F4550 and the PIC16F877A, everything works great, also much better speed than the cypress controler on my old icd2 clone.
There is only one strange problem, if i press halt while debugging, MPLAB hangs for about 4sec (target is still running) then the connection gets lost an the ICD2 gets reconnected and the debuggpointer is at 0.
I think its no hardware fault, but i can post the schematic this afternoon if needed.
I Used the hexfile from the "Short version of help for the ICD2" thread (ICD2_PIC18F4550_boot.hex and ICD2_PIC16F877A_boot.hex)
Some ideas?
greetings from germany
