Frequently Asked Questions
The SolidWorks 3-D models can be viewed in the SolidWorks application or in a free viewer, such as eDrawings (http://www.edrawingsviewer.com).
Logic PD provides a support infrastructure to assist customers in evaluating our products. Avenues for evaluation support include:
Schematics and PCB layout files are available in PDF format for SOMs and baseboards when the product has been registered on Logic's website.
Orcad schematics and layout files are only available for the baseboards.
A "custom BSP" is a BSP that Logic PD develops for a customer's specific needs. Logic PD does not support a custom BSP as a standard product. Custom BSPs are developed under contract with the customer.
These are accronyms for Logic PD's bootloader software.
Most of the processor signals are available on the SOM's expansion connector(s). Please refer to the specific SOM Hardware Specification manual for a complete reference.
No, the SOM does not have ESD protection.
The reason for this is that the SOM was designed to be adaptable to many different applications, which makes it impractical to design in ESD protection. The SOM does not provide any ESD protection circuitry on the board and must be provided by the product it is used in. Logic PD has extensive experience in designing products with ESD requirements.
Yes, our model numbers contain encoded information. Please refer to White Paper 293: Model Number Explanation & Decoder for specific information on Logic PD's Model Numbering scheme.
There is a maximum size of 1Kbytes (1024 bytes) for the boot string for Windows CE. This size includes the terminating NULL character, so you really only have room for 1023 characters plus the NULL character.
In order to gain access to Logic PD's Windows CE Binary BSP Components you will need to download and sign the BSP License agreement first. Logic PD provides the BSP free of charge for customers that are planning on designing the SOM into their final product. After Logic PD has recieved the signed license agreement you may be authorized by product sales for access to the LoCE Binary BSP.
A link to the license agreement is provided below, please follow the instructions contained in the document:
White Paper 293: Model Number Explanation & Decoder explains how to identify your product by part number, serial number, and model number.
Logic PD does not have an off-the-shelf Bluetooth driver available for Windows CE 5.0 BSP.
A memory map is available as part of the LogicLoader User Manual Addendum that is written for each SOM.
No, LogicLoader does not support RLE encoded bitmaps. Only uncompressed bitmap formats are supported.
No. For ARM 11 and later cores, the RealviewICE and RVDS development suite is required. An Abatron BDI 2000 is also compatible.
The Windows CE Run-time License Assessment Tool is designed to assist embedded developers in determining which run-time license applies to the custom operating system image they created using Windows CE 5.0.
The i.MX31 LITEKIT excludes the series resistors on the DDR interface for these reasons:
- Freescale testing on the IMX31 ADS kit found that series resistors provided little to no signal integrity improvement on DDR lines.
- Low power (mobile) DDR has drive strength control on chip.
- i.MX31 CPU has some drive strength control on DDR lines.
- All EMC compliance testing passed without series resistors.
The latest version of LogicLoader is always marked by (current) on the downloads page.
The build.sh file must use Unix end of line terminations.
The Windows CE 5.0 images we provide on the web do not properly display dialog boxes for landscape and widescreen PSP-style 480x272 resolution displays. The web images use the Quarter VGA Portrait resources, which assume a display at 320 pixels tall.
To fix this, load the .pbxml for the respective Windows image, remove the Quarter VGA portrait resources from the OSDesignView under "Shell and User Interface" -> "User Interface", and then Sysgen the build. Once those resources are removed, Windows CE will load using landscape QVGA resources that fit better on widescreen displays.
The i.MX31 LITEKIT uses the USB On-the-Go (OTG) port for ActiveSync connection.
