Hi All...

I have a board with a 644P and it works great. I just popped in a 1284P and used AVR Studio to upload the bootloader.

I am using the 0020 cores from avr-developers.com. I modified boards.txt so that there is an entry for the 1284P with a 16 MHz clock, since that's what my board is clocked at. I then compiled the blink example sketch and tried to upload it to the board. Here is what I saw:

Binary sketch size: 1222 bytes (of a 122880 byte maximum)
avrdude: AVR Part "atmega1284p" not found.

Followed by a long list of supported chips, of which the 1284P was not among them.

Is there something i can do to get this to work?

Thanks!

A newer version of avrdude includes configuration settings for the 1284P.  I have 5.10.  Arduino ships with 5.4.

You may be able to just "upgrade" the avrdude.conf file.  I've attached the version from my computer.

Awesome, thanks!

Now to push my luck a bit... Would you have a HEX file for a bootloader that clocks at 16 MHz? I thought i found one but I can't seem to get it to work :-(

I know this should be an wasy error to find int eh conf file, but line 320 looks fine to me, nd I retyped it to make sure there were no hidden characters. Here is the error avrdude spits out through the IDE:

Binary sketch size: 450 bytes (of a 32256 byte maximum)
error at C:\Users\jim\Desktop\arduino-0022\hardware/tools/avr/etc/avrdude.conf:320 unrecognized character: "a"

You are welcome.

Someone else will have to help with that one.  I have never built a bootloader and I don't have time right now to figure out how.

Argh!  Either the forum alters the file (e.g. changes line-feeds to carriage-return-line-feeds) or the you will need the latest avrdude to go with the new configuration file.


The choices available to you...

● I'll put the file somewhere else and you try again

● You locate the original source file (I think the project is hosted on SourceForge), download it, and try again

● You can "upgrade" to the latest AVR-GCC compiler...

If you would like to try the first choice, just let me know and I'll find a different home for the file.

Thanks! I got it working by taking the section that relatyes to the 1284P and pasting it into my existing avrdude.conf file. So that step is good.

Ah!  An option I had not considered.  Excellent choice.  I'm glad to know you have it working.  Good luck with a bootloader.
