6.4.1 Combining Two Images (.txt)

Each generated application .txt file has a header at the top and a terminating header at the bottom of the file. These files cannot be combined using text editors as is due to the presence of multiple start and terminating headers.

Image A Figure 6-7 Image A
Image B Figure 6-8 Image B

For example, one solution is to remove the terminating header as shown above in Image B and the start header from Image A (key value, reserved words, entry point). Both Image A and Image B have a header at the top and terminating header at the bottom of their respective files. Image A should be appended to the bottom of Image B. Once removed, we are able to successfully combine the two images in a single .txt file. Attention must be given to the address block of each image to ensure no data is lost.

Note: The order of merging Image A and Image B matters for what the CAN/MCAN boot loader will recognize as the starting point address for CPU1. If Image A should be the application image for CPU1 usage, Image A's terminating header should be removed and Image B's top header should be removed as well. Image B must then be appended to Image A's .txt file.
