Hi I am new to MCU, recently I got a stk500 and tried a few different code on it, all working fine except I uploaded the following code and it stopped working:

Code:

int main(void)

{

  // Set Port B pins as all outputs

  DDRB = 0xff;

  // Set all Port B pins as HIGH

  PORTB = 0xff;

  return 1;

}

I always get RC=-1 from avrdude.

Quote:

avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

According to http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=106325, I could have lock out my chip.

Can someone explain to me how to fix it, thanks

Your program is fine.

None of the LEDs are lit.

You must write 0 to light an LED on the STK500. It is known as 'active-low'.

Have you really got an AT90S8515 ?
That chip is obsolete. However it should still work ok for that program.

Did you mess with the clock selection fuses?

Also note that the STK500 used to ship with a mega8515 not an AT90S8515 so it seems unlikely it is an AT90S8515.

Anyway the AT90S8515 always required an external clock but the good news is that the STK500 is always in a position to supply one so I don't see how one could ever really "lose it"? Just ensure that the STK500 is jumpered to deliver its clock to the right pin.

Early STK500s (my first one) shipped with AT90S8515. A second one had the ATmega8515L.

I have read about it and all tutorial advice not to touch any fuses setting for beginner, so I didn't change any things with the word "fuse" on it

after the incident, I have changed the OSCSEL jumper to all the possible connection(on-board software signal, on-board crystal signal, not connected at all), still nothing.

So did I just fried my first chip? Shocked

Is there anything I can do to fix it?

Or should I turn the chip into this http://www.crookedbrains.net/2007/02/ic-old-transistors-got-new-use.html Laughing

additional info:

Code:

c:/>avrdude -c usbtiny -p at90s8515 -e -F

avrdude: initialization failed, rc=-1

avrdude: AVR device initialized and ready to accept instructions

avrdude: Device signature = 0x000000

avrdude: Yikes!  Invalid device signature.

avrdude: Expected signature for AT90S8515 is 1E 93 01

avrdude done.  Thank you.

The 8515 should be in SKT30000D3.
OSCSEL should be 1-2

Set the programmable clock to 3.6MHz in the HW Settings tab of Studio Programmer.

Set programmable VCC to 5V.

The underneath of your STK500 shows all the default jumper positions.

Believe me. Nothing is broken. Probably just a wrong setting.

David.

Hi David

I have moved the chip from SCKT3100A3 to SCKT3000D3, all the leds light up when I press reset. (nothing happen when the chip is in SCKT3100A3)

all my jumper is the default positions.

I don't think I can do these setting as I am still waiting for my usb serial cable to show up.

I tried to program it anyway after I moved the chip but still same error

Good to hear that Laughing

If you have got an old-stock STK500, it would have come with a green A5 paper manual. Read it while you are waiting for the mail to deliver your Serial cable.

Until you get the cable, the STK500 is fairly helpless.
All the same, I suspect that a virgin STK500 comes with VCC and Clock set to 5V and 3.6MHz.

So your TinyISP should be able to program the 8515. However it is a little more complicated to use an external programmer. e.g. do not supply power from the TinyISP.

David.

If your STK500 was very old stock, it might even have a 5V DataFlash chip near the PROGRAM button.

here are some picture of my stk500, I think it was made in 2004:

power was not supplied to the stk500, that was something you advised to me not to do in the other post, thanks David.

guess I will need to wait for my serial usb cable and tried your method.

Your TinyISP should be able to read the chip.

Connect to the RED 6-pin header according to the ISP pin-out in your green manual.

How did you get such a old stock ?

It looks as if pin#1 is not seated correctly in the SKT30000D3 socket.
You do not have a DataFlash chip.

David.

I have successfully program the chip twice today with default setting, and the chip working as expected, but then when I tried another code later, the chip just don't want to be program, weird!

No setting have changed

the voltage supply to the chip is 4.95v, is it suppose to be 5.0v? the power to the stk500 is 12v 600mA

I assume that you are using 'avrdude -c usbtiny'

Please quote your actual command(s)

We can't really do anything more than guesswork.
I presume that your serial cable was not in Saturday's mail. Perhaps it will arrive on Tuesday.

4.95V is fine.

David.

My serial to usb cable finally arrived today, and I managed to program the chip through serial high voltage programming, the chip is finally fixed.

but no support for at90s8515 in AVR Studio 5.1, bummer

You must have a lousy postal service in your country !

You will probably never get support in Studio 5.1
Buy a new chip(s).

Seriously, you should have got the 90S8515 working without HVPP.

It will take you a while to get used to all the facilities of your STK500. It is an excellent piece of kit.

David.
