The Loadable Firmware (LFW) from Hilscher includes the complete protocol stack and real-time kernel rcX. The LFW is regarded as a black box and is used in so-called companion chip solutions. To enable the netX to implement a specific protocol, the LFW is simply transferred to the netX.
This special firmware, designed as a 1-port variant, supports Single Pair Ethernet standard 10BASE-T1L.
Software development on the netX itself is unnecessary which shortens the time-to-market. A host controller accesses the netX dual-port memory and configures the LFW. A mailbox system then transmits the configuration data directly to the netX via the protocol packet API or configuration file created with the Hilscher tool chain. As soon as the protocol stack is configured, it provides cyclic and acyclic data at the host interface.
