__ _ __ _ __ ___ __ / / (_) /____ | |/_/___/ _ )___ ___ ________/ /__ / /__/ / __/ -_)> Intro -------- This repository contains the platforms/targets currently supported by LiteX: - The platform provides the defintion of the board:IOs, constraints, clocks, components + method to load and flash the bitstream to it. - The target provides a LiteX base design for the board that allows you to create a SoC (with or without a CPU) and integrate easily all the base components of your board: Ethernet, DRAM, PCIe, SPIFlash, SDCard, Leds, GPIOs, etc... The targets can be used as a base to build more complex or custom SoCs. They are are for example directly reused by the [Linux-on-LiteX-VexRiscv](https://github.com/litex-hub/linux-on-litex-vexriscv) project that is just using a specific configuration (Linux-capable CPU, additional peripherals). Basing your design on provided targets allow to to reduce code duplication between very various projects. First make to install LiteX correctly by following the [installation guide](https://github.com/enjoy-digital/litex/wiki/Installation). Each target provides a default configuration with a CPU, ROM, SRAM, UART, DRAM (if available), Ethernet (if available), etc... that can be simply built and loaded to the FPGA with: $ ./target.py --build --load You can then open a terminal on the main UART of the board and interact with the LiteX BIOS:

But this is just the starting point to create your own hardware! You can then: - Change the CPU: add `--cpu-type=lm32, microwatt, serv, rocket, etc... ` - Change the Bus standard: add `--bus-standard=wishbone, axi-lite` - Enable components: add `--with-ethernet --with-etherbone --with-sdcard etc...` - Load application code to the CPU from UART/Ethernet/SDCard, etc...: https://github.com/enjoy-digital/litex/wiki/Load-Application-Code-To-CPU - Create a bridge with your computer to easily [access the main bus of your SoC](https://github.com/enjoy-digital/litex/wiki/Use-Host-Bridge-to-control-debug-a-SoC) - Add a Logic Analyzer to your SoC to easily [observe/debug your design](https://github.com/enjoy-digital/litex/wiki/Use-LiteScope-To-Debug-A-SoC) - Simulate your SoC and interact with it at decent speed with [LiteX Sim](https://github.com/enjoy-digital/litex/blob/master/litex/tools/litex_sim.py)/Verilator. - Integrate external cores/CPU in your design. - etc... Please use `./target.py --help` to see the pre-built various possibilities. Hoping you will find this useful and enjoy it, please contribute back if you make improvements that could be useful to others or find issues! **A question or want to get in touch? Our IRC channel is [#litex at freenode.net](https://webchat.freenode.net/?channels=litex)** > **Note:** All boards with >= 32MB of memory and enough logic can be considered as Linux Capable.
