Shobos · « **on:** April 17, 2014, 10:09:06 pm »

I recently ordered Arduino with Atmega328P from ebay, but today when i got it on chip it says Atmega8A-PU and in Arduino IDE when i try to load blink example it says this following error 'avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.

Is there anyway i can get it working ?

How about treating it as an atmega8-based arduino?

What You mean by that ?

Change the board type in the menu.

Shobos · « **Reply #4 on:** April 17, 2014, 10:32:39 pm »

I already tried that now it says 'avrdude: stk500_getsync(): not in sync: resp=0x00'...

Would it even have the bootloader on it?

Get a refund.

I rest my case.

assuming you've plugged it in

If you've selected 'arduino-ng with atmega8' from the boards menu and it doesnt load your sketch - no bootloader.

if you have another arduino or an avr programmer you can burn a bootloader, but otherwise....

Shobos · « **Reply #9 on:** April 17, 2014, 11:23:26 pm »

I have only one Arduino, so basically im doomed ?

dannyf · « **Reply #10 on:** April 18, 2014, 12:01:01 am »

Based on the little information you have provided, yes.

Shobos · « **Reply #11 on:** April 18, 2014, 12:06:47 am »

What more info do Ya need ? Maybe i have missed something....

dannyf · « **Reply #12 on:** April 18, 2014, 12:10:51 am »

I actually need nothing.

You do.

Shobos · « **Reply #13 on:** April 18, 2014, 12:33:56 am »

You need info in order to help me. As i said, I am new to this stuff....I am just asking for help. As i said, I gave You all info that i am aware of, maybe i missed something.

Provide link to listing you purchased.

Provide photo showing what you got.

Shobos · « **Reply #15 on:** April 18, 2014, 01:50:57 am »

http://www.ebay.com/itm/301105919701?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 i Dunno why it shows 59 $ price now because I got it for 9,58 dollars. What i got is this http://imageshack.com/a/img834/4746/keic.jpg

sleemanj · « **Reply #16 on:** April 18, 2014, 02:02:37 am »

I'd contact the seller and request refund, the listing states all specs as for 328, but the board has an 8. You can see the differences here

If they don't, paypal dispute.

Shobos · « **Reply #17 on:** April 18, 2014, 02:05:10 am »

Already did that. So there isnt any way to make this work right ?

Skimask · « **Reply #18 on:** April 18, 2014, 02:06:22 am »

Listen closely......

No.

Shobos · « **Reply #19 on:** April 18, 2014, 02:12:39 am »

Lol, ok.

If it doesn't have a bootloader, and you don't have an ISP programmer, or another arduino to act as one, then you can do nothing.

I wouldn't bother anyway, there is no sense in using an ATMega8, the 328 is what you want.

Unless you want to use "shields", then I would just buy a Pro-Mini from ebay, make sure it's the 5v 16MHz version. And a CP2102 based USB - Serial adapter.

If you do want to use "shields", then I would buy a Diavolino from evilmadscience.com and solder it yourself, because you learn something doing that, even if it's just soldering practice (and the Diavolino's look cool). And again, a CP2102 adapter.

Shobos · « **Reply #21 on:** April 18, 2014, 02:20:52 am »

Awesome, thanks for info ! But i have one small question(again), if i buy Atmega328P already with bootloader and put it in this board, will it work ?

miguelvp · « **Reply #22 on:** April 18, 2014, 02:22:38 am »

Could he buy an ATmega328P-PU and replace the chip?

The picture in Ebay clearly shows it's a ATMega8A-PU and they say it's "compatible" shady, and for what, 14 cents price difference?

You can find the chip from Ebay for $3 free shipping from china (couple of months to get it?) and hopefully they don't cheat you again. From mouser etc with shipping $10 but your best bet is to ask for a refund and/or dispute.

Shobos · « **Reply #23 on:** April 18, 2014, 02:31:59 am »

The funny fact is that there is second this very same Arduino coming because orginally, this one was missing while it was in transist, so i said them to send another one, but today this 'missing' Arduino came.....

seems like a good idea to help OP

TBH, seems expensive for a chinese knock-off ...
