README: add initial contents and list of supported boards.
2020-07-25 14:21:51 -04:00
This repository contains the platforms/targets currently supported by LiteX:
README: add board picture and fix a few typos.
2020-07-27 02:53:12 -04:00
- The platform provides the definition of the board: IOs, constraints, clocks, components + methods to load and flash the bitstream to it.
README: add initial contents and list of supported boards.
2020-07-25 14:21:51 -04:00
- 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...
README: add board picture and fix a few typos.
2020-07-27 02:53:12 -04:00
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 allows to to reduce code duplication between very various projects.
README: add initial contents and list of supported boards.
2020-07-25 14:21:51 -04:00
README: add links to LiteX's wiki.
2020-07-27 05:05:14 -04:00
First make sure to install LiteX correctly by following the [installation guide](https://github.com/enjoy-digital/litex/wiki/Installation) and have a look at the [LiteX's wiki](https://github.com/enjoy-digital/litex/wiki) for [tutorials](https://github.com/enjoy-digital/litex/wiki/Tutorials-Resources), [examples of projects](https://github.com/enjoy-digital/litex/wiki/Projects) and more information to use/build FPGA designs with it.
README: add initial contents and list of supported boards.
2020-07-25 14:21:51 -04:00
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:
<p align="center"><img src="https://raw.githubusercontent.com/enjoy-digital/litex/master/doc/bios_screenshot.png"></p>
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...`
README: add board picture and fix a few typos.
2020-07-27 02:53:12 -04:00
- [Load application code to the CPU](https://github.com/enjoy-digital/litex/wiki/Load-Application-Code-To-CPU) over UART/Ethernet/SDCard, etc...
README: add missings .
2020-07-27 05:44:25 -04:00
- 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).
README: add initial contents and list of supported boards.
2020-07-25 14:21:51 -04:00
- 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.
README: add board picture and fix a few typos.
2020-07-27 02:53:12 -04:00
- Integrate external cores/CPU to create your own design.
README: add initial contents and list of supported boards.

Please use `./target.py --help` to see the pre-built various possibilities.
