wolfSSL for Renesas RA Evaluation Kit (EK-RA6M4)
Description
This directory contains e2studio projects targeted at the Renesas RA 32-bit MCUs. The example projects include a wolfSSL TLS client. They also include benchmark and cryptography tests for the wolfCrypt library.
The wolfssl project contains both the wolfSSL and wolfCrypt libraries.
It is built as a Renesas RA C Library Project
and contains the Renesas RA
configuration. The wolfssl project uses Secure Cryptography Engine on RA6 Protected Mode
as hardware acceleration for cypto and TLS operation.
The other projects (benchmark, client, and test) are built as a
Renesas RA C Project Using RA Library
, where the RA library is the wolfssl project.
The wolfssl Project Summary is listed below and is relevant for every project.

5.) Prepare SEGGER_RTT to logging
-
Download J-Link software from Segger
-
Choose
J-Link Software and Documentation Pack
-
Copy sample program files below from
Installed SEGGER
folder,e.g C:\Program Files\SEGGER\JLink\Samples\RTT
, to /path/to/wolfssl/IDE/Reenesas/e2studio/RA6M4/test/src/SEGGER_RTT\SEGGER_RTT.c
SEGGER_RTT.h
SEGGER_RTT_Conf.h
SEGGER_RTT_printf.c -
To connect RTT block, you can configure RTT viewer configuration based on where RTT block is in map file
e.g.
[test_RA6M4.map]COMMON 0x200232a8 0xa8 ./src/SEGGER_RTT/SEGGER_RTT.o\
you can specify "RTT control block" to 0x200232a8 by Address
OR
you can specify "RTT control block" to 0x20020000 0x10000 by Search Range
Run Client
1.) Enable TLS_CLIENT definition in wolfssl_demo.h of test_RA6M4 project
2.) Client IP address and Server IP address
- Client IP address can be changed by the following line in wolf_client.c.
static const byte ucIPAddress[4] = { 192, 168, 11, 241 };
- Client IP address can be changed by the following line in wolf_client.c.
#define SERVER_IP "192.168.11.40"
3.) Build test_RA6M4 project
4.) Prepare peer wolfssl server
- On Linux
$ autogen.sh
$ ./configure --enable-extended-master=no CFLAGS="-DWOLFSSL_STATIC_RSA -DHAVE_AES_CBC"
Run peer wolfSSL server
RSA sign and verify use, launch server with the following option
$./examples/server/server -b -d -i
ECDSA sign and verify use, launch server with the following option
$./examples/server/server -b -d -i -c ./certs/server-ecc.pem -k ./certs/ecc-key.pem
5.) Run the example Client

End of Client Example
Note
Multi Client session use case is only able to run threads that all use either SCE cipher suite or SW cipher suite.
The example program runs two threads that use SCE cipher suite.
Run Crypt test and Benchmark
1.) Enable CRYPT_TEST and/or BENCHMARK definition in wolfssl_demo.h
2.) Enable SCEKEY_INSTALLED definition in user_settings.h if you have installed key for AES
In the example code for benchmark, it assumes that AES key is installed at DIRECT_KEY_ADDRESS which is 0x08000000U as follows:
#if defined(SCEKEY_INSTALLED)
/* aes 256 */
memcpy(guser_PKCbInfo.sce_wrapped_key_aes256.value,
(uint32_t *)DIRECT_KEY_ADDRESS, HW_SCE_AES256_KEY_INDEX_WORD_SIZE*4);
guser_PKCbInfo.sce_wrapped_key_aes256.type = SCE_KEY_INDEX_TYPE_AES256;
guser_PKCbInfo.aes256_installedkey_set = 1;
/* aes 128 */
guser_PKCbInfo.aes128_installedkey_set = 0;
#endif
To install key, please refer Installing and Updating Secure Keys.
You can update code above to handle AES128 key when you install its key.
3.) Run Benchmark and Crypto Test
