PS2Mouse from bryce firmware problem

[FRAGKI-2012]

I made the ps2mouse adaptor for cpc and the pic programmer , I took the hex program from bruce so that I program my pic but an error appears. The error says: " Varify failed at address 0000h! " The steps that I follow are:
I adapt the program in the right settings and I open the hex file that I have downloaded from cpcwiki  and then I click on "program all" .
Can anyone help me to solve my problem?
Thanks

Could the PIC be write protected?

[FRAGKI-2012]

probably not!!!

[FRAGKI-2012]

is any way to check that ?

PICs don't have write protection, only read protection (known as Code Protection) to stop someone from extracting your code. But even with that turned on, you can over-write the PIC.

Right, you can overwrite - but you can't check. So a check of 'is data written correctly' could produce the above error message. Any other ideas?

No, when you do a "Write and Verify", the data is written, then verified and only then does the Code Protect bit gets set and user decides whether Code-Protect is set or not with and option in the PC program he's using. So you can still do all the verifying you want.
