6.8.2 Functional Mode

In Functional Mode, the Master System’s bootloader looks for a valid image in the serial flash memory, interfaced over the QSPI port. If a valid image is found, the bootloader transfers the same to Master System’s memory subsystem. The image format contains the MSS application code and the radar subsystem patch code.

If a valid image (or the QSPI Serial Flash is not found), the bootloader initializes the SPI port and awaits for the image transfer. This operation comes handy for configurations where the IWR1443 is interfaced to an external processor which has its own nonvolatile storage hence can store the user application and the IWR1443 device’s firmware image.
