+# RT-Thread Port
+## Overview
+You can enable the wolfSSL support for RT-Thread available [here](https://www.rt-thread.io) using the define `RTTHREAD`.
+
+## Usage
+
+wolfSSL supports a compile-time user configurable options in the `IDE/ECLIPSE/RTTHREAD/user_settings.h` file.
+
+The `wolfssl_test.c` example application provides a simple function to run the test and benchmark.
+
+1. Open your IDE-based example project for RT-Thread.
+
+2. Create the following folder and sub-folders structures in your project.
+```
+wolfssl
+   |src
+   |wolfcrypt
+          |benchmark
+          |src
+          |test
+   |wolfssl
+          |openssl
+          |wolfcrypt
+   |example
+```
+The folder hierarchy is the same as the wolfSSL folders with an exception of the example folder.
+
+3. Add or link all of the header and source files in `IDE/ECLIPSE/RTTHREAD/` folder into the example folder.
+
+4. Add or link all the source code in the corresponding folder in wolfSSL.
+
+5. Remove non-C platform dependent files from your build.
+
+6. In your C/C++ compiler preprocessor settings, add the wolfSSL directories to your include paths.
+Here's an example of the paths that must be added.
+
+```
+$PROJ_DIR$\...
+$PROJ_DIR$\...\wolfcrypt
+$PROJ_DIR$\...\wolfssl
+$PROJ_DIR$\...\IDE\ECLIPSE\RTTHREAD
+```
+
+7. In your C/C++ compiler preprocessor settings, define the WOLFSSL_USER_SETTINGS symbol to add user_settings.h file in your project.
+
+8. Add a call to `wolfssl_test()` from your startup task. Here's an example:
+
+```c
+static void test_task (void *p_arg)
+{
+    ...
+    while (1) {
+           wolfssl_test();
+           rt_thread_mdelay(500);
+        }
+}
+```
+9. Rebuild all your project.
+
+10. Now you are ready to download and debug your image on the board.
+
+
+The test results below were collected from the RT-Thread ART-Pi with the following software and tool chains:
+
+- STM32H750XBH6
+
+- RT-Thread Studio (Version: 2.0.0)
+
+- GNU ARM Cross C Compiler (Optimization level: -O0)
+
+- The starting project is based on [RT-Thread ART-Pi SDK](https://github.com/RT-Thread-Studio/sdk-bsp-stm32h750-realthread-artpi) (./projects/art_pi_wifi)

+# Building wolfSSL with DSP Use
+
+## Intro
+This directory is to help with building wolfSSL for use with DSP. It assumes that the Hexagon SDK has been setup on the machine and that the environment variables have been set by calling (source ~/Qualcomm/Hexagon_SDK/3.4.3/setup_sdk_env.source). Currently offloading ECC 256 verify operations to the DSP is supported. When WOLFSSL_DSP is defined ECC verify operations are offloaded to the aDSP by default. When not in SINGLE_THREADED mode a call back function must be set for getting the handle or a handle must be set in the ecc_key structure for the operation to make use of multiple threads when offloading to the DSP. This is because creating new handles for new threads must be done.
+
+
+## Building
+The directory is divided up into a build for the CPU portion in IDE/HEXAGON and a build for use on the DSP located in IDE/HEXAGON/DSP. Each section has their own Makefile. The Makefile default to an Ubuntu + hexagon v65 release build but can be changed by using V=<build type>. An example of building both would be:
+
+```
+cd IDE/HEXAGON
+make V=UbuntuARM_Release_aarch64
+cd DSP
+make V=hexagon_Release_dynamic_toolv83_v65
+```
+
+The results from each build will be placed into the ship directories of each, for example ./UbuntuARM_Release_aarch64/ship/* and ./DSP/hexagon_Release_dynamic_toolv83_v65/ship/*.
+The Makefile creates a DSP library libwolfssl_dsp_skel.so, library libwolfssl.so, executable benchmark, example ecc-verify, example ecc-verify-benchmark and executable testwolfcrypt.
+These then need pushed to the device in order to run. An example of pushing the results to the device would be:
+
+```
+cd IDE/HEXAGON
+adb push DSP/hexagon_Release_dynamic_toolv83_v65/ship/libwolfssl_dsp_skel.so /data/rfsa/adsp/
+adb push UbuntuARM_Release_aarch64/ship/libwolfssl.so /data/
+adb push UbuntuARM_Release_aarch64/ship/benchmark /data/
+adb push UbuntuARM_Release_aarch64/ship/eccverify /data/
+adb push UbuntuARM_Release_aarch64/ship/eccbenchmark /data/
+```
+
+To change the settings wolfSSL is built with macros can be set in IDE/HEXAGON/user_settings.h. It contains a default setting at this point that was used for collecting benchmark values. The macro necessary to turn on use of the DSP is WOLFSSL_DSP.
+
+
+The script IDE/HEXAGON/build.sh was added to help speed up building and testing. An example of using the script would be:
+
+```
+cd IDE/HEXAGON
+./build.sh Release
+```
+
+This will delete the previous build and rebuild for Release mode. Then it will try to push the resulting library and some of the executables to the device.
+
+
+For increased performance uncomment the -O3 flag in IDE/HEXAGON/Makefile and IDE/HEXAGON/DSP/Makefile.
+
+## Use
+
+A default handle is created with the call to wolfCrypt_Init() and is set to use the aDSP. A default mutex is locked for each use of the handle to make the library stable when multiple threads are calling to DSP supported operations.
+To use wolfSSL with a user created handle it can be done by calling wc_ecc_set_handle or by setting a callback function using wolfSSL_SetHandleCb(). This should be set in the case of multithreaded applications to account for having a handle for each thread being used.
+
+
+#### wolfSSL_SetHandleCb
+The API wolfSSL_SetHandleCb takes a function pointer of type "int (*wolfSSL_DSP_Handle_cb)(remote_handle64 *handle, int finished void *ctx);". This callback is executed right before the operation is handed off to the DSP (finished set to 0) and right after done with the handle (finished set to 1). With ECC this would be after the ECC verify function has been called but before the information is passed on to the DSP and once again with the finished flag set after the result is returned.
+
+The callback set should return 0 on successfully setting the input handle. The ctx argument is for future custom context to be passed in and is currently not used.
+
+#### Expected Performance
+This is the expected results from running ./eccbenchmark using the -O3 flag
+
+benchmarking using default (locks on handle for aDSP)
+5000 verifies on 1 threads took 17.481616 seconds
+10000 verifies on 2 threads took 35.324308 seconds
+
+benchmarking using software (+NEON if built in)
+5000 verifies on 1 threads took 1.398336 seconds
+10000 verifies on 2 threads took 1.383992 seconds
+

+10000 verifies on 2 threads took 19.215413 seconds
+15000 verifies on 3 threads took 20.410200 seconds
+20000 verifies on 4 threads took 23.261446 seconds

 # Static Library: Building libwolfssl.sgx.static.lib.a for use with SGX Enclaves
 
 ### Requirements:
-This code was created to use Intel's SGX hardware. It is expected that the user has gone through the steps of both turning on the hardware in bios if needed and has installed the necesary software from Intel to make use of the hardware. (https://software.intel.com/en-us/sgx) If these steps have not been done then it is expected that the user is familure with simulation software being used in place of hardware.

+
+### Security:
+If not already in use, it is recommended that SP (single precision) RSA and ECC code is used. This will help mitigate potential side channel attacks. To use SP code check that wolfcrypt/src/sp_c32.c and wolfcrypt/src/sp_c64.c are compiled and add HAVE_WOLFSSL_SP=1 to the build command to define the necessary macros.
 
 ### Overview and Build:
 This project creates a static library to then link with Enclaves. A simple example of an Enclave linking to the created wolfSSL library can be found in wolfssl-examples on github. This project has been tested with gcc 5.4.0 on Ubuntu 16.04.
+When building with tests the file wolfssl/options.h is expected, in downloaded bundles from wolfssl.com this file exists but when building from a cloned version of wolfSSL from GitHub then the file needs created. This is done either through cd wolfssl && ./autogen.sh && ./configure && ./config.status or by cd wolfssl && touch wolfssl/options.h.
 
 To create the static library, simply call make:
