Compression of Windows CE Images in Flash Memory
Eurotech stores its Windows CE operating system images (nk.bin) in non-volatile onboard flash of its ARM-based products. At power-up, the bootloader copies the image into onboard DRAM, and the Windows CE kernel subsequently starts up and executes from DRAM.
Windows CE images can be compressed to conserve flash storage space (for larger user flash disks), or they can be left uncompressed for faster boot time. Standard Eurotech Inc products (e.g. BitsyXb, GCM, Sphere) use compressed images, while standard Eurotech Ltd products (e.g. Titan, Viper) use uncompressed images.
You can determine if your CE image is compressed by reviewing the CE.BIB or MAKEIMG.OUT files, both of which are included with standard Eurotech Inc CE releases.
The CE.BIB file uses the following flag to enable image compression:
COMPRESSION=ON
Likewise, the MAKEIMG.OUT text file lists the size of the files with the following two entries:
Raw files size: xxxxxxxx
Compressed files size: xxxxxxxx
