MultiZone® Trusted Firmware is the quick and safe way to build secure IoT applications with any RISC-V processor. It provides secure access to commercial and private IoT clouds, real-time monitoring, secure boot, and remote firmware updates. The built-in Trusted Execution Environment provides hardware-enforced separation to shield the execution of trusted applications from untrusted 3rd party libraries.
lwIP is a small independent implementation of the TCP/IP protocol suite that has been initially developed by Adam Dunkels and is now continued here. The focus of the lwIP TCP/IP implementation is to reduce resource usage while still having a full scale TCP. This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM.
