i cant believe this 9500 character limit so i had to split it into 7 posts, please go forth and read pardon if i sound at all rude but ive seen so many tutorials im getting sick of the links to one another, ive been trying to burn a bootloader to sevral chips using my arduino uno with NO luck, i just got 3 atmega8 chips completely blank no bootloader, so i tried all methods of burning a bootloader for use with internal 8mhz tutorials, if you can google it(with all kindsa peramiters in search) ive looked at and tried it, i DO NOT HAVE and WILL NOT BUY external crystals for sevral reasons, i have NO MONEY to buy any, and if i dont need one (as it seems) i wont use one for saving on space, time, money, and parts, if i was ABSOLUTELY SURE it would work if i bought a crystal i would buy 1 but im not so i wont, so please do not ask me to do so I SERIOUSLY NEED HELP PEOPLE im no expert at any programming language but im very smart and can follow STEP-BY-STEP instructions, please for the love of god DO NOT "LINK" TUTORIALS just lay out what i need to do HERE
im running Ubuntu/linux 12.04 w/Arduino IDE 1.0

slight alteration to delay(40) to (20) and i think thats it // this sketch turns the Arduino into a AVRISP // using the following pins: // 10: slave reset // 11: MOSI // 12: MISO // 13: SCK
// Put an LED (with resistor) on the following pins: // 9: Heartbeat - shows the programmer is running // 8: Error - Lights up if something goes wrong (use red if that makes sense) // 7: Programming - In communication with the slave // // October 2009 by David A. Mellis // - Added support for the read signature command // // February 2009 by Randall Bohn // - Added support for writing to EEPROM (what took so long?) // Windows users should consider WinAVR's avrdude instead of the // avrdude included with Arduino software. // // January 2008 by Randall Bohn // - Thanks to Amplificar for helping me with the STK500 protocol // - The AVRISP/STK500 (mk I) protocol is used in the arduino bootloader // - The SPI functions herein were developed for the AVR910_ARD programmer // - More information at http://code.google.com/p/mega-isp

as you can see ive got quite a few boards ive tried already with avrdude: stk500_recv(): programmer is not responding when i use a pull-up resistor and avrdude: stk500_getsync(): not in sync: resp=0x## with different # each time and even sometimes get avrdude: stk500_getsync(): not in sync: expect:0x## or something to that effect, im stressing hard guys i need your help somebody anybody tell me what im doing wrong and what i need to do to fix this problem, or atleast a step in the right direction, please for the love of god DO NOT "LINK" TUTORIALS just lay out what i need to do HERE

Follow this tutorial: http://pdp11.byethost12.com/AVR/ArduinoAsProgrammer.htmReplace the atmega328p with your atmega8 and do not add any crystal and capacitors. By doing so you can burn any code you like in your atmega8, including a bootloader if you really want to write one. In most cases, for stand alone applications, the bootloader is not necessary.

If you don't use a crystal or ceramic resonator on your atmel mcu, then the clock frequency will very probably not be accurate enough for the bootloader to work even if you do manage to burn it. However, you can still use ArduinoISP to upload your sketch directly, without a bootloader. See http://miscsolutions.wordpress.com/2011/08/09/prototyping-small-embedded-projects-with-arduino/ for how I used to do it before I purchased an AVRISPmkII.

Good point. And now that the IDE has a 'upload using programmer' option one can really easily live without messing with bootloaders at all. And seeing that an arduino board running the arduinoISP sketch becomes a hardware programmer, there is a lot to be said for just not messing with bootloaders. Just think your mega boards won't suffer if you want to use the WDT or if your compiled code happens to have a !!! string for random data in it, it won't hang the upload. One could make a good argument to 'just say no' when the subject of bootloaders come up.  Lefty

i cant believe this 9500 character limit so i had to split it into 7 posts, please go forth and read
You can attach files to your post you know. Making 7 posts just to attach files is a mis-use of the forum. You can attach multiple files, or make a single .zip file. please for the love of god DO NOT "LINK" TUTORIALS just lay out what i need to do HERE If there is a tutorial, that explains what to do, why should it be copied and pasted here, when you just have to go to a link? The tutorial might have photos, etc.
