Hi Oren,

Are the config bytes written correctly? If you read them back, do they have
the correct value? They are NOT included in the CRC, and you'll have to
issue a CCP command before programming them.

If you can't find anything, I'd read back all the config bytes from a device
programmed with the Philips programmer, using your own programmer. That is
the only area where the chip can be different if the CRC matches.

Hello Eric,

Sending the CCP seem to solve it.

Thank you.
