WARP 13 programmer error message

[Minmin]

Hi,

I'm using WARP 13 as PICSTART plus under MPLAB for pic 16f877, I have use it for two months, it works fine, but today I keep on getting error message: "Program Memory or EEPROM Data is protected. Reprogram the entire part." Anyone know what's wrong?

Thanks

Minmin

Hi Minmin:

I've been using WARP-13A for 2 years (upgrading it's firmware when it's needed) and it's a great programmer. The PIC you're using has info into it's EEPROM you must rewrite to program. Click the option (Up and into your rigth hand) that allows you to program the EEPROM.

Hope it will helpfull.

Regards;

Joan

Joan,

Thanks for your reply. I tried the EEPROM program, put tick in that check box It still didn't work. I tried to just program the configuration bits, Still not work, it read all 0. I checked the help menu under warp 13, it states, even device is code protected, it still can program the configuration bits, I did check the signal and voltage for this five pins, I'm using isp programming, it all correct, vpp is 12 v, vcc is 5v, rb7 and rb6 is 5 v. So the only probability is my PIC chip on dlp245pb board is damaged, or I acciently change the pid/vid burned in EEPROM on dlp245pb this is what dlp support told me the possible reason.

I will let you know the results as soon as I get a new dlp board.

Hi Minmin:

If you've programmed the PIC with the option "Code Protect ON" you will never read nothing from the PIC ... you will read all "0". This is the pourpose of Code Protect.

One probe you can do is to program the same PIC in stand-alone mode. If the PIC is programed when inserted into the WARP-13 ZIF socket then the problem is in your dlp245pb PCB. If not, then your WARP can be damaged.

If possible I don't recommend ISP because you can damage your programmer easily.

As I said, I'd programmed thousands of PIC's (12,16,18 Family), EEPROMS, etc, and I never had any kind of problem.

For your info, my WARP-13A software is 1.09.07 (9th March 2004) and the programmer is RX28 v1.6. You can actualice them (software & Firmware) from the web of New Found Electronics:

I hope you will solve the problem

Best Regards;

Joan

Joan,

I got new dlp board just now, I could sucessfully download program, So the problem is PIC 16f 877, I still don't understand how Can I so easily to damage it. Also In your last email, you say using ISP will hurt programmer, so What shall I pay attention? And what shall I do not to damage my PIC chip next time?

Thank you

Minmin
