Porting Guide

..
├──Demo just for test.
├──Platform peripherals drivers.
├──Port porting files for different third-party libraries, like LWIP, FreeRTOS, MbedTLS.
└──Wifi wifi manager, APIs and driver library.
1. In Demo, there are four parts as follows:
..
├──Application main.c and some demo that shows how to use wifi.
├──FreeRTOS RTOS used in demo project, FreeRTOS V10.3.1.
├──RT-Thread RTOS used in demo project, rt-thread v4.0.3.
├──Lwip Lwip used in demo project, lwip V2.1.2.
├──Mbedtls Mbedtls used in demo Project, based on Mbedtls-2.17.0 and added support for GD32W51x Hardware Accelerator.
└──Project demo projects.
In Project, there are four projects as follows:
..
├──FreeRTOS_MbedTLS_LWIP this demo project support FreeRTOS, HW accelerated Mbedtls and LWIP
├──FreeRTOS_ROM-MbedTLS_LWIP this demo project support FreeRTOS, Mbedtls(has implemented in ROM) and LWIP
├──RT-Thread_MbedTLS_LWIP this demo project support RT-Thread, HW accelerated Mbedtls and LWIP
└──RT-Thread_ROM-MbedTLS_LWIP this demo project support RT-Thread, Mbedtls(has implemented in ROM) and LWIP
user can choose different project according to different requirements.
2. In Platform, there are basic peripherals drivers and boot setting for GD32w51x, and the startup.s and .c file.
3. In Port, there are five parts ad follows:
..
├──Bsp higher level APIs based on the basic peripherals drivers.
├──Config contains platform_def.h can set some special settings for chip or demo board.
├──Lwip contains port files when use Lwip in project.
├──Mbedtls contains only the TLS handshake process，must cowork with ROM MbedTLS which contains bignum, crypto, hash and other algorithms.
└──OS porting files for RTOS-FreeRTOS/RTT.
4. In Wifi, there are all the files when use wifi, user would not change before porting to project; and wifi api in wifi_management.c
and wifi_netlink.c is recommended to use.
Note:
1. In project.sct files, the start address of SRAM is 0x20000200, cause the first 512B is used for ROM code to put some global variables.
2. ROM MbedTLS can save code size stored in Flash, and can accelerate encryption and decryption operation for wifi.
