Programming problem

[MobyUK]

Hi. I'm having trouble programming 18F45K22 micros with the U2 programmer. The HEX file has been used multiple times before but now I get the following error message:

"Configuration verify error at 0000.
0200 should be 3200
Continue verifying?"

Any ideas

I do not know about the U2 programmer but in similar cases I had to erase first before programming.

Hi. Thanks for the tip.
I tried it but still no success but what I found was if I erase the chip, then read it back, reload my hex file, then it seems to programme ok.
Weird. I've been using the Melabs U2 programmer for years and never had to go through that process.

Did you get the latest PBP3.1.5 update? If so, you need to update the U2 software as well. If you did update both, maybe there's a new bug in one of the two.

I get that same error with my U2 with PIC16F819. The message will either be "Target device does not match specified device", "Configuration verify error at 0000" or "Configuration verify error at 0000 or 0200 should be 3200 Continue verifying?" Except I get different numbers for 0200 and 3200.

Did you erased it first?
