Hello!

So finally i got my little Case for the Atmega ready and so i wanted to start setting up some Chips with the Bootlaoder.

I am using the parallelport for installing it and i get that error: (I found some answers on the internet, but i diont know what to to with them. :/ (they are talking about burning an hex file and so on. ;) ))

ok herse the code:

So maybe can give me some hint to solve that problem. :(

thx, HU

no Idea? :(

How do you have your circuit setup for programming? I have written a step by step for installing a bootloader. It can be found in the Library Howto for installing the bootloader. The circuit needed to install is sligtly different than that of the standard Nerdkit setup.

Hi Rick!

I got the Circuit per mail from Humberto :

Here you go. You need five wires between various parallel port pins and the breadboard. You also need your new chip wired up as usual, with the crystal and all.

The bootloader source code, which is fairly complicated, is included in the source code in the downloads section of our site. That involves removing the wire on MCU pin 1 (the RESET line), and plugging the parallel port wires in as follows: LPT pin 1 ==> MCU pin 19 LPT pin 2 ==> MCU pin 17 LPT pin 11 ==> MCU pin 18 LPT pin 16 ==> MCU pin 1 LPT pin 19 ==> GND After that, you can go into the "bootloader" directory, and type "make". Hopefully, you'll get a successful verification from avrdude. Note that this will remove that default "Congratulations" program, so now you need to remove the parallel port header, replace the wire on the RESET line, and use the serial port to upload the "initialload" code. If on Windows you may also need to set the port name to LPT1, and also to install the "giveio" driver which is included with the WinAVR package.

Ok. Good News. It didn work for me on Windows. So i installed xubuntu and hoped it would work... AND it did! wihout any problems. :)

Yeah.
