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\
