BUILD/INSTALLATION
DISCLAIMER: Not for production use. This is an unfinished project and under development. I am not responsible for what may happen to the motherboard or printer. Use only at your own risk.
Currently you can only flash this firmware using a flasher (stlink, jlink, bmp etc).
Before flashing this firmware (optional, but recommended):
I recommend making a backup of your firmware. At least your bootlaoder (addresses from 0x08000000 to 0x08010000). This way, you can always recover/return to stock firmware by:
If you don't perform this step, and, just in case of brick, there are copies of stock firmware ET4 releases and bootloader below on resources section.
Flashing this firmware:
There are several tutorials available for stlink/j-link flashers.
This firmware lacks of bootloader, so you have to flash it from address 0x8000000.
You can connect with pronterface to corresponding com port @115200bps.

Marlin 2.0 Bugfix Branch
Not for production use. Use with caution!
Marlin 2.0 takes this popular RepRap firmware to the next level by adding support for much faster 32-bit and ARM-based boards while improving support for 8-bit AVR boards. Read about Marlin's decision to use a "Hardware Abstraction Layer" below.
This branch is for patches to the latest 2.0.x release version. Periodically this branch will form the basis for the next minor 2.0.x release.
Download earlier versions of Marlin on the Releases page.
Building Marlin 2.0
To build Marlin 2.0 you'll need Arduino IDE 1.8.8 or newer or PlatformIO. We've posted detailed instructions on Building Marlin with Arduino and Building Marlin with PlatformIO for ReArm (which applies well to other 32-bit boards).
Hardware Abstraction Layer (HAL)
Marlin 2.0 introduces a layer of abstraction so that all the existing high-level code can be built for 32-bit platforms while still retaining full 8-bit AVR compatibility. Retaining AVR compatibility and a single code-base is important to us, because we want to make sure that features and patches get as much testing and attention as possible, and that all platforms always benefit from the latest improvements.

License
Marlin is published under the GPL license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
