Bootloader --> ATmega328P-PU

Hello all,

I have a simple problem... for some reason I am unable to get the arduino bootloader onto my ATmega328P-PU. I initially tried just doing it through the arduino environment using an uno board. However, there appears to be some sort of winusb/jungo driver conflict that I am not able to resolve. If someone could explain to me how to uninstall the jungo driver and install the winusb driver that would be great.

I also tried using AVR studio with an AVR-ISPmkII. I tried a few different bootloader hex files which had reasonable names and it seemed like the fuses and lock bits were all read appropriately. It said it programmed ok but then the bootloader didn't work.

I don't care which approach I use, but I want to be able to put the bootloader on the 328Ps and then proceed to program arduino code onto the chips. Please point me to a walkthrough or provide step by step instructions.

Thank you.

P.S. I am using Windows7

Are you able to upload Sketches to your Uno? Does the code seem to run correctly?

Yes, but on a different chip, obviously. I cannot upload to the chip that does not have the bootloader yet...

I recommend setting up your Uno to act as an ISP...

I think this is the shortest path to your goal. The only hitch in your giddy up is that "step 1.5" is missing from the instructions...

maybe you should try it on wimows xp. :slight_smile:

Have you tried the same programmer on different computers ?

I have USBtiny ISP and I upladed bootloader by avrdude. If you have these two, I can send you instructions... but... DON'T forget to set up the fuse bits or you can kill your chip :slight_smile:

Regards,
Peter
