Description

A standard embedded device or module usually executes a firmware. The firmware is a file stored on the hardware either as a binary in FLASH sectors or in a file system.
On netX90 and netX4000 devices, the ROM loader is responsible to start such a firmware.

Because of several options (e.g. XiP / hardware layout / security requirements), such a firmware is not always able to update itself in FLASH.

Therefore a so called Maintenance Firmware (MFW) is introduced. This firmware is a dedicated / standalone firmware offering the necessary services to update a regular firmware (LFW).

Function overview:

  • Basic firmware (Recovery firmware) which is started if there is no regular firmware available or if it fails to start.
  • Perform a firmware download or update (replacing) an existing firmware.
  • Support additional downloads for configuration and other files.
