Previous GSoC participation: This is my first time applying for GSoC, I'm an Electronics enthusiast and have a great interest in fields like FPGA, Digital VLSI, Computer Architecture. I have experienced with Intel's Quartus, Xilinx's vivado, and opensource toolchains for ice40. I have also done many projects related to Cyclone2, Upduino3.0(ICE40), Sipeed Tang Primer FPGA.

About your project

Project name: Beaglewire Software Support

Description

Introduction

The BeagleWire is an FPGA development platform that has been designed for use with BeagleBone boards. BeagleWire is a cape on which there is an FPGA device (Lattice iCE40HX). The software support for BeagleWire is still in the development phase. In this project, I'm developing and testing the existing software support of Beaglewire.
The known primary issue in Beaglewire is the interface between 32MB SDRAM and ICE40HX4K. For this Solution, I'm going to try options like LiteDRAM(a small footprint and configurable DRAM core) or Advanced SDRAM controller provided by LATTICE.

Why LiteDRAM for SDRAM Control

The Core produced by LiteDRAM is
1. Fully pipelined, high performance.
2. Configurable commands depth on bankmachines.
3. Auto-Precharge.
4. Periodic refresh/ZQ short calibration (up to 8 postponed refreshes).

LiteDRAM is already used in commercial and open-source designs
Testing of I2C, SPI, PWM, UART

In this project I'm going to test all the subsystems like I2C, SPI, PWM, UART in Hardware and the primary goal will be to debug the issues related to it and fix it accordingly

  •  ;I2C: There are two grove Connectors on BeagleWire for I2C, I will test the current Verilog Code of I2C in hardware, and will found out if further improvements can be done or not.
  •  ;UART: The existing code of Uart will be tested in hardware, and few examples also will be added for UART.
  •  ;PWM: The PWM driver code can be extended for Servo driver. The new servo driver will also

Timeline

Provide a development timeline with a milestone each of the 11 weeks and any pre-work. (A realistic timeline is critical to our selection process.)
