Thank Sylvain, That is: RT-Thread RTOS (GPLv2) Application (GPLv2, PIC ELF) #1 + CyaSSL like (GPLv2) Application (close source, PIC ELF) #2
It's little like: Linux Kernel (GPLv2) + some Applications(GPLv2) + some Applications (close source) But the application is not like Linux application, which uses system call to invoke system function in Linux. RT-Thread application will be dynamically linked with system APIs and invoke system function directly. Because RT-Thread supports applications, there is an Arduino like board: ART, which has STM32F4 MCU and will use this mechanism to run applications. There are also a WIFI shield, therefore, lwIP will be used in ART board.
