Linux LiteX demo

This example design features a Linux-capable SoC based around VexRiscv soft CPU. It also includes DDR and Ethernet controllers. To build the litex example, run the following commands:

To build the linux-litex-demo example, first re-navigate to the directory that contains examples for Xilinx 7-Series FPGAs. Then, depending on your hardware, run:

Arty 35TArty 100T

TARGET="arty_35" make -C linux_litex_demo

At completion, the bitstreams are located in the build directory:

linux_litex_demo/build/<board>

Now you can upload the design with:

TARGET="<board type>" make download -C linux_litex_demo
