Wow ... this porting has just beend finished. It probably has bugs yet, but it works !

It is a porting of Cortex M0 Real Time Operating System (M0S) of Dumitru Stama, winner of hack a day 1kb 2017 contest (http://hackaday.com/2017/01/13/1-kb-challenge-and-the-winners-are/). Original version is for NUCLEO-F072RB and is available at https://github.com/dumitru-stama/M0S .

This port is for Arm Cortex M0 Design Kit running under Xilinx FPGA of Digilent Basys 3 board. You will need obfuscated verilog release of Cortex M0 (https://developer.arm.com/products/system-ip/corelink-interconnect/cortex-m-system-design-kit) .

Synthesis takes a lot of time because of the logic syntehsided 4kb rom/ram .

This porting has been tested and used under RWindoW$

1. Download this repository .

2. Put this file (https://github.com/CarlosDomingues/TEAM-SUCCESS-NANO/blob/master/cortexm0ds_logic.v) in your \CM0XilinxBasys3DesignKit-master\EXAMPLE_SoC\ARMSOC_1\Xilinx\ARMSOC_1.srcs\sources_1\imports\CM0DS-DesignKit\AHB_Peripherals\CM0DS_AHBL folder.

3. Install arm-non-eabi (https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads) and put it in path

4. Xilinx Install Vivado

5. run Command Prompt, enter in Software\M0s folder and run build .

6. Open Vivado Project Under Xilinx folder, run Generate bitstream and download it to you Basys 3 board.
