pic16c505 programming faild at code address 0000h
Hi, I think nearly everyone who has used IC-prog has received this error at some point. I know I did. A few quesitons:
What programmer are you using?
Is your PC a laptop or a desktop?
What speed is this PC?
What OS are you using? Win2000/XP requires different settings in the software.
How long is your serial cable?
Unfortunately, that 'verifying error at address 0000h' is an error when nearly anything is wrong. Since, while its programming, the PC doesn't get any 'feedback' it just assumes the micro is there and starts to program. But when it verify's, thats the only time it checks that the micro is there, powered up, and programmed. The PC cannot 'read' you micro. Theere could be many reasons.
If it fails at address 0000h, then it fails right at the begining. This is possibly a problem with your serial port,, and the softwares ability to access it (2000/XP requires an extra uitility, so non-windows programs can access it).
Also, check you hardware, like the others suggested. If you only want to program the F84A (or other PIC 18 pins micro's) then this is a stable and simple programmer design:
**broken link removed**
Anthoer thing. Try 'reading' the micro. If you get all 'FFFF's then the micro is powered, erased, and you are reading it correctly. Then it may be a problem with the VPP/MCLR voltage, should be >13v.
However, if you get 0000's then you are not reading it properly, and something is wrong.
Any other hex numbers displayed, would probably be your program you downloaded into your chip when you last programmed it, its just your verify that failed.
IC-prog has a forum, and its full of questions like this. Ask there, I'm sure someone knows how to fix it.
Good Luck,
