# 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.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
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](https://embarc.org/embarc_osp/doc/build/html/board/emsk.html) 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](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/releases), [ARC GNU prebuilt toolchain](https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases) and [OpenOCD for ARC](https://github.com/foss-for-synopsys-dwc-arc-processors/openocd>)
|
||
|
|
|
||
|
|
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](http://zadig.akeo.ie) to replace the default FTDI driver with WinUSB driver. See [How to Use OpenOCD on Windows](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/wiki/How-to-Use-OpenOCD-on-Windows>) for more information.
|
||
|
|
|
||
|
|
After compile, please use the following cmds to debug
|
||
|
|
|
||
|
|
scons --gdb
|
||
|
|
|
||
|
|
|
||
|
