gen 7 boothloader trouble

Hi,
Ive built a gen 7 1.5 board with a 20 Mhz Crystal. Im having trouble with uploading the repeter host firmware, it either gives me a problem on my pc which is running windows xp that says "problem connecting to board" or on my other laptop thats running windows 7 it gives us an error of 0x00 or something like that. Ive had the boothloader externally installed by my supplier as it was a factory fresh atmega 1284 p-pu .Ive currently purchased a pololu avr programmer but im not sure how to use it as im not a programmer .Ive also downloaded Avr studio 6, loaded the pololu drivers onto the programmer , but im unable to programme the boothloader.

please help me solve this problem.

Never follow the instructions in the wiki. They have worked for too many people already, so reading them is moot.

Hi

Will you kindly help me with how to go further with it?

I'm only using the Arduino IDE to do my development, here's how I did it (assuming you have already got avrdude on your machine)

Step 1) Download "Gen 7 Arduino IDE Support" (http://reprap.org/wiki/Gen7_Arduino_IDE_Support) and put it onto your PC
Step 2) Extract contents of Gen 7 Arduino IDE Support and find the Gen7\bootloaders\Gen7 area - you're looking for a file called "bootloader-1284p-20mhz.hex"
Step 3) Set fuses appropriate for the chip: avrdude -c PROGRAMMER -P PORT -p m1284p -U lfuse:w:0xF7:m -U hfuse:w:0xDC:m -U efuse:w:0xFC:m
Step 4) Plug your programmer into the programming header on the board (3x2 pin array next to the chip) and then run the following command: avrdude -c PROGRAMMER -P PORT -p m1284p -U flash:w:bootloader-1284P-20MHz.hex

As majic79 mentioned.
The PROGRAMMER name for the pololu AVR programmer is avrispv2, this is the name that you use in the course of following the instructions linked above.
[www.pololu.com]
[www.pololu.com]

So you should have "avrdude -c avrispv2 -P PORT -p m1284p -U lfuse:w:0xF7:m -U hfuse:w:0xDC:m -U efuse:w:0xFC:m

PORT should be whatever windows says the avr programmer is using in windows device manager.
