Synopsys DesignWare ARC EM Starter Kit

Overview

The DesignWare™ ARC™ EM Starter Kit(EMSK, emsk) is a low-cost, versatile solution enabling rapid software development and software debugging, and profiling for the ARC EM Family of processors. The EM Family includes the EM4, EM6, EM5D, EM7D, EM9D, and EM11D cores.

EM Starter Kit

The EMSK consists of a hardware platform and a software package, including pre-installed FPGA images of different configurations of the ARC EM Processor with peripherals.

The development board is based on a Xilinx Spartan-6 LX45 FPGA. It supports hardware extensions using six 2x6 connectors supporting a total of 48 user I/O pins (plus power and ground pins) that can be used to connect components such as sensors, actuators, memories, displays, buttons, switches, and communication devices. A Digilent Pmod™ compatible extension board containing a four-channel 12-bit A/D converter with an IIC interface and an AC power adapter are included in the package.

Usage

FPGA Configuration

Current, only em9d configuration is supported and tested for RT-Thread. However, it's can be easily applied to other configurations because all emsk configurations almost share the same memory map and periphreals.

Please refer EMSK configuration for details.

Toolchain

The ARC GNU Toolchain offers all of the benefits of open source tools, including complete source code and a large install base. The ARC GNU IDE Installer consists of Eclipse IDE with ARC GNU plugin for Eclipse, ARC GNU prebuilt toolchain and OpenOCD for ARC

Here, the ARC GNU toolchain is installed to c:\arc\gnu. If not, please change the path configuration in rtconfig.py.

Compile

please run the following cmds to compile

cd <rt-thread-root>/bsp/synopsys/emsk_em9d
scons

Debug

You need to install Zadig to replace the default FTDI driver with WinUSB driver. See How to Use OpenOCD on Windows for more information.

After compile, please use the following cmds to debug

scons  --gdb

Supported Drivers

Driver Supported Comment
UART1 yes USB-UART for shell & log
UART0 yes PMOD A UART for UART modules, e.g. esp8266
