The circuit on Atmega8 is not flashed (perhaps burned out or incorrectly compiled), what should I do?

Question

Iron

I created and assembled my first circuit, but when I try to read the signature or flash an error occurs, (screen) the same error occurs if the programmer is not connected to the circuit, i.e. it turns out that he doesn’t see it, he flashed it through khazama 1.6, maybe the controller itself burned out, it’s powered by 6V (4 AA batteries), the usbasp programmer, I’m attaching the diagram
to the drawing: I know about the wrong connection of the LED, another l293d with 2 electric motors is also connected (not indicated in the drawing)

Answer 1

1. Are ground and power connected to the controller at all? This is not indicated on the diagram.
2. Is the pinout of the firmware connector correct? Not confused, say, MISO and MOSI? Check twice.
3. Is the programmer alive? Did you manage to flash anything through it before?
4. Try lowering the supply voltage to 4.5 V (3 batteries) and replace the controller.

Answer 2

From your "diagram" the pinout of the programming connector is absolutely incomprehensible and it is not at all clear whether you have connected VCC and GND at the controller. Because you drew only the AVCC output for the controller, and scored the bolt on the rest.
1pF on power - why? You don’t switch megahertz there, set it to 0.1 uF.
