HII,
My name is Shreyas. I'm a 13year old kid 
,
I stay in Mangalore (Mangalore, Karnataka, India),
I am working on a project to make an arduino with a little more I/O pins ....... using an atmega32a-au TQFP ....... can someone please send me the extra core files/bootloader files to burn the arduino bootloader into my microcontroller (atmega32a-au TQFP) using arduino uno ............ SOMEONE PLEASE HELP ME OUT SOON ????? ......
Best Regards
@Shreyas....
Normally these kinds of posts go unanswered because you have addressed too many wants and needs... However, considering your age of 13, I may have done something similar at the time I was your age 51 years ago!
First, a bit of etiquette ... try and address your question in a mature nanner, maybe like; "... I am interested in building a 32U4 board for learning Arduino; could someone point me to the information I will need, such as core files and bootloader, etc."
The first problem is that the 32U4 does not come in DIP, so you would be soldering a small, surface mount device. If you have advanced soldering experience, maybe this is possible, but I think it is too difficult for a 1st-time project. But, your message suggests that you may already have the microcontroller and board - I will continue as if you have these parts and deal with the core/bootloader.
The 32U4 is the microcontroller used in the Leonardo Arduino board; therefore, the bootloader and the schematic. are available from here.
But, the Pro Micro by Sparkfun does the same thing as the Leonardo, in a small package: Here.
Adafruit has a similar offering: Here.
SO, some choices. You can check on the web who in your area sells Arduino, Adafruit, or Sparkfun products.
For Leonardo, the core files & bootloader files are already in the Arduino IDE download,
For Adafruit or Sparkfun, the links are on the URL references I provided.
As a student, you should write to the corporate offices of Arduino in Italy and Adafruit/Sparkfun in the USA to request information on any educational programs that they may sponsor which would benefit young teenage students; specifically ask about training in India and about any educational discounts which may be available. Be polite, do not beg, write properly, and be sincere.
Good luck. Old, but may be useful; here

Hello Sir,
I'm very thankful for your reply,
Yes sir I can solder smd devices (components) ..... But sir i'm looking for the bootloader for an atmega32a-au tqfp NOT an atmega32u4....
Best Regards
For a bootloader, point your "Additional Boards manager url" preference to here: https://github.com/Optiboot/optiboot/releases/download/v6.2/package_optiboot_optiboot-additional_index.json
and use the board manager (requires 1.6.4) to download Optiboot6.2.
This includes a version of the bootloader for Atmega32. Use "burn bootloader" using Arduino as ISP.
Supposedly it works 
(You can also simply download the source from github.)
If you want to use the Arduino pin-oriented functions (digitalWrite() and so on), you'll also need to create a "variants/xxxx/pins_arduino.h" or equivalent; the optiboot download provides ONLY the bootloader. There is a very old set of core files for ATmega32 (and others) at http://avr-developers.com/
This is ... a lot of work ... if all you want is more pins. You might be better off using one of the semi-commercialized ATmega1284 boards.
