I cant burn bootloader on my atmega328p-pu using blank UNO R3 board. Just for the record, You can burn bootloader into this chip using board WITHOUT second chip, right ? And I dont have any other ISP that I could use...
Thanks in advance.
"You can't get there from here"
To burn a bootloader, you must have an ISP.
This could be a standalone ISP (like the USBASP, though there are a few others) or you can use an Arduino uno - but in that case, it must be a working arduino uno, with an ATmega328p with a bootloader, running the Arduino as ISP sketch (included with the Arduino IDE)
Right now, you have wires going from the poor, terrified, naked chip (I cannot endorse that method of connecting to a chip. If you can't cost justify a ZIF socket, at least use a basic socket, preferably with some breadboard or prototyping board to make life easier on yourself) into the Arduino Uno board... where they're connected directly to the empty socket.

Thans for info, But I think i abandon Arduino as I am fed up withe problems it has.
Part of the problem is probably that you started with a chinese copy of the Arduino Uno, instead of the real thing. The real ones all come with a properly bootloaded chip, and work out of the box.
The knockoffs vary widely in terms of how much you have to fart around with them to make them work, and based on posts on these forums, a significant portion of supposedly pre-bootloaded atmega328 chips sold on ebay actually aren't (they're either unprogrammed or the bootloader is the wrong one or and old/unsupported version).

The Arduino is fine. Cheap rubbish from eBay isn't.
Good luck with another board, if you buy it with price as the main criteria. How much did you save? $5?
The board worked absolutely flawlessly with 328p-pu that I ordered separate that already had bootloader, but I managed to damage the chip because I was connecting faulty H-bridge that fried the chip. Guess what Nick, for some people $5 is alot of money. And no, I got it for free, the board IS Chinese, but its actually pretty good for China product, decent soldering, brand regulators and caps etc
