7.3 Firm ware Upgrades
The possible interfaces that can be used for upgrades of the flash memory device are shown in Figure 5.
With the standard firmware implementation, firmware upgrades are achieved by using the module SPI master port to
directly program the module flash device. Avnera provides a GUI application that runs on a PC to facilitate direct SPI
programming.
By means of additional custom firmware, programming of the module flash device can be achieved via the slave I2C or
SPI host interfaces.
It is also possible to implement over-the-air programming of the Rx module so all elements of a system can be upgraded
through a single host interface. This requires working with customer to define the functionality and architecture required as
well as the customer host interface and API to the Tx module.
