The last one week i try to program a pic 16f628a, i'made a home built jdm programmer, and used icprog to program it, the first times it seemed to work, the burning was succesful, but after a few days nothing worked, i had the usual problem "Verify failed at address 0000h" (the address depends to the first nonzero address). I thought that maybe there was a problem with my programmer and i have rebuilt it 3 times... but there's still the same problem. So i concluded that the problem is with the software.. So i testes with both winpic800 an icprog and there's the same problem. Today i found that when i read the chip in the configuration byte it has the cp bit checked and i wonder what can i do now to remove it, I have tested 3 pics but all of them are code protected..
Any idea???
