RPC on FreeRTOS or bare metal


RPC on FreeRTOS or bare metal



I want to implement an RPC-communication using FreeRTOS to configure hardware over an ethernet-interface.



With FreeRTOS comes an Protocol-Stack including Ethernet, IP and TCP/UDP (lwIP). I'm not forced to use TCP or UDP. In doubt i could use the lowest Protocol-Level (Ethernet) but due to packet-loss and detection of corrupt packages i prefer the TCP/UDP-Level.



My goal is to archieve a simple rpc-communication between FreeRTOS-Server and a client-application on Linux for example and build my application on top of it - the client sents arguments to the server, the freertos server configures itself accordingly. My main question here is: Are there any example-implementations for me to build on to get startet fast (usage of the lwIP-Package would be outstanding)?



So far, eRPC comes closest to my scope. Its independent of any OS and good documented. But it lacks examples for TCP.
JSON-RPC also looks promising.



Hope someone can point me to some sources i haven't found yet.
