Need help programming 12f629

[talkboxier]

So I got a couple 12f629's and i have been trying to flash them, but to no success. I am using icprog with a an olimex pic-P8-1 programmer, which is connected to a usb-to-serial connector on my laptop.

I keep getting a verify failed at 0000h error every time I try to program. i never get this when I read the chip, or even flash with the read data.

anybody have any ideas?

The Olimax is a prototyping board, NOT a programmer - you need a programmer to program the chip.

well thats lovely. Would you happen to know any schematics to build one?

Except JDM's are the worlds most unreliable programmers, and don't normally work off USB/Serial converters.

Best bet is to buy a PICKit2 or PICKit3 - the days of cheap parallel/serial programmers are long over, as are the ports.
