COM iMX6 WinCE

WEC7 Tools

CE Remote Display Application

The Remote Display allows to operate the target device's Win CE desktop from a Windows PC. It requires a USB ActiveSync connection.

Download X86 remote display application (over ActiveSync connection)

Usage

1. Extract the zip file on your PC.

2. Wait for the ActiveSync connection to be ready.

3. Start ASRDisp.exe.

Binary BSP user guide

1. Download binary BSP (Please have a look at the iMX6 Downloads section.).

2. Unzip the files to any folder on your PC.

3. Call link-DHCOM_iMX6_BIN_GEN.bat file in the folder ...\DHCOM_iMX6_BSP_BIN\, to generate symbolic links in the \WINCE700\ folder.

4. Start Visual Studio 2008 with WEC7 platform builder.

5. Open platform builder project DHCOM_iMX6.pbxml at location C:\WINCE700\OSDesigns\DHCOM_iMX6_WEC7\.

6. Select retail build.

7. Call build --> rebuild solution to build the WEC7 image.

8. After the image build has completed successfully, the nk.nb0 image is stored at location C:\WINCE700\OSDesigns\DHCOM_iMX6_WEC7\RelDir\_1_Retail_DHCOM_iMX6_ARMV7\.

9. Copy the new nk.nb0 to your mircoSD card and restart the system.

Note: To delete the symbolic links (see 3.) please call unlink-DHCOM_iMX6_BIN_GEN.bat file in the folder ...\DHCOM_iMX6_BSP_BIN\

WEC2013 Debugging

1. Enable connection to WEC2013 device via Telnet. DH electronics recommends PuTTY for Telnet connection.

Notes: PuTTY can be downloaded from www.heise.de. Default IP address is 192.168.1.110. No Login is used with the testsystem.

2. Before the Remote Debug session can be started it is necessary to start two applications via the telnet connection, by using the following commands:

• START conmanclient3.exe
• START cmaccept3.exe

NOTE: If you boot up the device, you have to start the service conmanclient3.exe once. The service cmaccept3.exe needs to be start before you will deploy or debug your application. The service cmaccept3.exe is closed automatically after 3 minutes. Be sure to connect your application with the device during this time period. Otherwise you have to start the cmaccept3.exe again. The files are stored in folder \windows\ at testimage.

3. Now the debug session can be started from visual studio.

WEC2013 VNC Connection

With WEC2013 efonVNC is used for remote desktop connection. For more information and license click here.

1. vncconfig.exe can be used to configure password and connection details (stored in folder \apps\wec2013\ at testimage).

NOTES:

• default password: dhcom_imx6
• default port number: 5900
• Configuration is stored in registry at path [HKEY_CURRENT_USER\Software\RealVNC\WinVNC4]

2. winvnc.exe (stored in folder \apps\wec2013\ at testimage) must be started. This is done atomatically at startup with the testimage. Otherwise the application can be started via telnet.

3. Download VNC viewer provided by RealVNC for PC/Laptop from here. For more information and license click here.

4. Run VNC viewer application and connect the device by using IP address and port number.

NOTES:

• default IP address: 192.168.1.110
• default port number: 5900

WEC2013 Remote Tools

Before remote tools can be used, it is necessary to sstart some applications on WEC2013 Device.

1. Enable connection to WEC2013 device via Telnet. DH electronics recommends PuTTY for Telnet connection.

Notes: PuTTY can be downloaded from www.heise.de. Default IP address is 192.168.1.110. No Login is used with the testsystem.

2. Before the Remote Debug session can be started it is necessary to start two applications via the telnet connection, by using the following commands:

The service cmaccept3.exe is closed automatically after 3 minutes. Be sure to connect your application with the device during this time period. Otherwise you have to start the cmaccept3.exe again. The files are stored in folder \windows\ at testimage.

3. Now it is possible to use remote tools from Visual Studio
