Flash Storage
In addition to the RAM-based storage standard on Windows CE vehicle computers, the vehicle computer is
also equipped with a non-volatile Flash-based storage area which can store data (partitions) that can not be
corrupted by a cold boot. This Flash area is divided into two categories: Flash File System (FFS) Partitions and
Non-FFS Partitions.

FFS Partitions

The vehicle computer includes two FFS partitions. These partitions appear to the vehicle computer as a hard
drive that the OS file system can write files to and read files from. Data is retained even if power is removed.
The two FFS partitions appear as two separate folders in the Windows CE file system and are as follows:
Partition Table not Valid -33 The size of flash memory is different than that described in the
partition table. Retry the download with the correct partition table
file.
Invalid file format -34 The file format is invalid. Only Symbol HEX files are supported by
IPL.
