7. If one of the partitions being built is the Splash Screen, a prompt appears requesting both the source
Bitmap file and the destination HEX file.
8. A check is performed and if there are no errors, the partition hex files are created.
If the build fails, the hex files are not be created and TCM displays an error message. Two of the most common
reasons for a build failure are:
•
Files defined in the script can not be found. This error can occur when the files referenced by the script
are no longer stored on the development computer or the folders where they are stored were renamed.
•
The total amount of flash memory space required by the script exceeds the image size. To correct this,
reduce the number of files in the partition or increase the size of the partition. See Defining Script
Properties on page 7-8 for more information about setting the image size appropriately.

Once the hex file is built, it can be downloaded to the vehicle computer.
