7.1.5.2 Combing CPU1 and CPU2 Firmware Images

The F28P65x LFU implementation supports sending the CPU1 and CPU2 firmware together in a combined image. To create this image, simply concatenate the CPU2 firmware image to the CPU1 firmware image from the TI ASCII hex file output.

For example, see the following snippet from a combined image file:
