Original Mega 2560 bootloader about megacore

[MCUdude]

Hi!

It's correct that I removed the legacy stk500v2 bootloader option from the v3.0.0 version of MegaCore. I did it to simplify the tools menu, and also to push users towards using the new but superior Urboot bootloader.

You can always ask them to install an older version of MegaCore or create a script that calls Avrdude directly. You can also use PlatformIO, which allows you to specify whatever programmer or bootloader you want.

The main difference between v3.0.0 and v2.2.3 versions is the migration to Urboot. If you downgrade to v2.2.3, you don't miss out on any core features apart from the new bootloader.

However, what I could do for the future v3.0.1 release is to provide a legacy upload option for the default Arduino MEGA bootloader. I would recommend absolutely everyone to replace their default bootloader, but if this isn't an option, MegaCore could still be used. I'll probably implement under the Programmers menu.

Thanks!
I downgraded to v2.2.3 and is now working again. :-)

And yes, I would very much like to see an option in v3.0.1 to "somehow" be able to use the old (original) Arduino Mega boot loader. For users of my software that have little experience with software and Arduino's, it would be nice if they are able to use the Arduino Mega board out of the box, thus without changing the bootloader. For them the Arduino IDE may be familiar, but they may not know PlatformIO.

Bye, Aiko

I've just released v3.0.1
In this version, it's possible to upload using the original Arduino MEGA bootloader by selecting "Legacy Arduino MEGA bootloader" programmer option and clicking "Upload using programmer" to upload code using the default bootloader. However, I'll highly recommend replacing it with Urboot if possible.
