Hey, guys I have been diligently searching the internet for information about my problem but cannot figure it out.
I have just switched from the 16f876 and am now trying to use the 18f252.
I loaded microcode's 18f252 boot loader using a JDM programmer and WinPic 800. The ICD cannot communicate with the chip for some reason. If I push the Loader information button it will tell me I have a different pic every time. Also I tried making a hex file for a blinking led and then programming it with WinPic but it blinked erratically. Tried a second chip, same thing. I used the same 20mhz resonator for the 16f876 and it works fine.

Any Ideas what might be wrong? I would really appreciate any tips.
