开发环境搭建

Cochlear 公司提供的模块只能在 MATLAB 2012a 及以下的版本运行。这带来不少的麻烦。需要完成配置

  • 软件环境：
    1. Windows 7 64-bit
    2. MATLAB 2012a 64-bit 1
    3. Windows SDK 7.1, or Visual Studio 10.0 Professional with SP1
    4. Speedgoat driver 7
  • 硬件环境：
    1. Desktop PC
    2. Speedgoat target machine
      • 1615 (new)
      • 1273 (old)

出现的问题

安装 Windows SDK 7.1 失败

Installation of the "Microsoft Windows SDKfor Windows 7" product has reported the following error: Please refer to Samples\Setup\HTML\ConfigDetails.htm document for further information.

参考 Microsoft Support

To resolve this issue, you must uninstall all versions of the Visual C++ 2010 Redistributable before installing the Windows 7 SDK. You may have one or more of the following products installed:

  • Microsoft Visual C++ 2010 x86 Redistributable
  • Microsoft Visual C++ 2010 x64 Redistributable

After uninstalling the Microsoft Visual C++ 2010 Redistributable products, you may install the Windows 7 SDK. After installing the Windows 7 SDK, you may then reinstall the newer version of the Visual C++ 2010 Redistributable products, in order to restore the Visual C++ 2010 Redistributable products to their original state.

配置 MATLAB & xPC

  1. Run MATLAB as administrator
  2. Set mex compiler by mex -setup
  3. Set xpc compiler by xpcsetCC -setup
  4. Set target kernel by rtwintgt -setup

安装 speedgoat driver

  1. Download the latest driver
  2. Go to the driver folder
  3. Run speedgoat_setup
  4. Restart MATLAB

配置 target machine

Run xpcexplr on 32-bit MATLAB to set target machine

Note: you will get error on 64-bit MATLAB

IP address 192.168.7.1
TCP/IP target port 22222
LAN subnet mask address: 255.255.255.0
TCP/IP gateway address 255.255.255.255
TCP/IP target driver I8254x
Multicore CPU support enable
Graphic mode enable

Run the commander tools on 64-bit MATLAB to set target machine

参考： MATLAB hep system "xPC Target"—"User's Guide"—"Configuring Environment From the MATLAB Command Line" 

 1: tgs=xpctarget.targets;
 2: tgs.makeDefault('TargetPC1');
 3: env=tgs.Item('TargetPC1');
 4: env.HostTargetComm='TcpIp';
 5: env.TcpIpTargetAddress='192.168.7.1';
 6: env.TcpIpTargetPort='22222';
 7: env.TcpIpSubNetMask='255.255.255.0';
 8: env.TcpIpGateway='255.255.255.255';
 9: env.TcpIpTargetDriver='I8254x';
10: env.SecondaryIDE='on';
11: env.MulticoreSupport='on';

Make a boot disk on the host PC

Run speedgoatmachineboot('X:')

Transfer the kernel and make a boot disk

  1. Insert the boot disk to an USB port of the target machine
  2. Restart the target machine to load the new kernel
  3. Check the display information of the target machine
  4. For the new target machine (1615), you have to disconnect the USB keyboard when it boots up, otherwise it will fail (strange). You can reconnect the keyboard after it boots up.

配置 host PC

  1. Connect the host and the target via a Ethernet cable. Make sure that the cable inserts to the correct "Host Link" port.
  2. Set IP address (TCP/IPV4) of the host
    • IP address: 192.168.7.2
    • Subnet mask: 255.255.255.0

测试 host-target 通讯连接

  1. xpctargetping success
  2. xpctest success
  3. Speedgoat full system test (run demos)

新的问题：SN1615无法启动 <2014-03-05 Wed>

两台机器中新的一台SN1615（另一台是SN1273）无法启动，先以为是BIOS的设置问题，就发了封信去Speedgoat公司问。他们发了个BIOS设置截图过来，设置后还是不行。

突然发现把键盘拔掉就成功启动了，启动后插上键盘也能用。真奇怪。不过问题总算搞定了。

Upgrade MATLAB to R2014a <2014-03-10 Mon>

MATLAB makes a lot of improvement in xPC development in this release (Today!). We will use this version as the main development tool.

Changes I found as far.

  • xPC changed to Real-Time Windows Target+Simulink Real-Time
  • xPC target machine kernel changed
  • Microsoft Visual Studio 2012 provides better support than 2010

Footnotes:

1

这里必须说一下，如果 64-bit 的 Windows7 安装了 32-bit 的 MATLAB，将无法 使用 xPC 连接 target machine。
