I am just starting out trying to program ATMEL's ATMEGA32A-PU microcontroller using my arduino uno R3 as the ISP programmer. I was following the tutorial found here: http://hackaday.com/2010/10/23/avr-programming-introduction/
This tutorial describes programming an ATMEGA168 chip. I looked up the datasheet for the ATMEGA32 and adjusted the wiring, I believe, correctly and I'm using avrdude to program the chip.
I am running Windows 10 x64. I downloaded WinAVR-20100110.
From the hackaday instructions I loaded my arduino with the ArduinoISP sketch from FILE->examples in the arduino IDE. I made no changes.
The pins on the atmega32 chip are connected thus:
6 (MOSI) to arduino 11
7 (MISO) to arduino 12
8 (SCK) to arduino 13
9 (RST) to arduino 10
10 (VCC) to 5v
11 (GND) to GND
30 (AVCC) to 5v
31 (GND) to GND
I am using the arduino's 5v and GND pins to supply power and ground to the AVR.
From a cmd prompt I am running: avrdude -v -P COM3 -b 19200 -c avrisp -p atmega32 -U flash:w:main.hex

avrdude done. Thank you.
It goes through the programming and says it succesfully wrote 144 bytes. I've also tried using stk500 since the output of the command above mentions it but I get a timeout error when I do that. For testing purposes all I'm trying to do is get 8 LED's from PORTD to light up. I'm including avr/io.h and
int main(void)
{
DDRD |= 0xff; //Set PortD Pins as an output
PORTD |= 0xff; //Set PortD Pins high to turn on LEDs
while(1) { } //Loop forever
}
Unfortunately, PD1 is the only led to light up. None of the rest do anything.
I have the microcontroller connected to a breadboard with pins 14-21 each connected to its own 470 ohm resistor. The resistors each connects to its own LED which then connects to ground.
So the problem was in the makefile. I didn't realize the AVR was listed in the makefile that I downloaded from the instructions from the hackaday tutorial. Once I changed the MCU, AVRDUDE_PROGRAMMER, and PORT in the makefile it worked like a charm.
