[Solved] Board definition files, board is not listed.

Hello!
I would like to use a Pro Mega 3.3V@8Mhz with the current Arduino IDE.
Before i updated to the current IDE version from a fairly old one it worked.
After the Update the board no longer shows up in the selection dialog.

The board definition files reside in /hardware/ inside my local arduino subfolder.
I have not moved or altered them as far as i can remember.

Before the update the dialog was different, i only had to select a board, the processor selection dialog is new.
Is that what caused this to happen, incompatibility with the new IDE?

How can i fix this?

Greetings,
Peter

Go back to an older IDE? I'm still using 1.0.6, no Due/Yun boards so no need to go to 1.6.x.

Yes indeed, that would be the best solution.
But the available IDE versions on the website all show the same behaviour.

Due to boneheaded decisions by the Arduino developers, custom cores are not compatible between 1.0.x and 1.6.x (worse still, you can't even make one that works with both due to capricious changes to how boards.txt specifies the bootloader path)

Plus

bootloader.path doesn't work anymore, so you need to fix that.

To put it mildly, I'm very disappointed in how this was handled in 1.6.x.

You can still download 1.0.6 http://arduino.cc/en/Main/OldSoftwareReleases

What is a "Pro Mega"? I've heard of the "Arduino Pro Mini" (by sparkfun) and I see that Arduino also supports the "Arduino Pro" (also by sparkfun) but I don't see a "Pro Mega" on the Arduino product page: http://arduino.cc/en/Main/Products. Since it is running at 8 MHz you can't use it as a regular Arduino Mega 2560. Does sparkfun make it? Do they provide Arduino 1.6 support for it?

I found that I had to move my third-party 1.0 "boards.txt" files another level deeper in the /hardware folder.

Thank you, that was it. For some reason i was certain i had the 1.5.n before i upgradet to 1.6 and gave up testing older versions after the 3rd installation.

I downgradet to 1.0.5 and everything is fine again, no silly extra processor selection and the board definitions work again!

It is just a ATMega2560 on a board with nothing else besides a 3.3V regulator, sold by Sparkfun.
