wolfSSL Benchmark Example

The Example contains of wolfSSL benchmark program.

  1. idf.py menuconfig to configure the program.
    1-1. Example Configuration ->

    BENCH_ARG : argument that you want to use. Default is "-lng 0"
    The list of argument can be find in help.

When you want to run the benchmark program

  1. idf.py -p <PORT> flash to compile and load the firmware
  2. idf.py monitor to see the message

See the README.md file in the upper level 'examples' directory for more information about examples.

Performance

Reminder than when building on WSL in /mnt/c there will be a noticeable performance degradation at compile time. Using ~/ will be faster at the cost of shared filesystems.

Example build on WSL:

Optionally install wolfSSL component
# cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF
./setup.sh

cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF/examples/wolfssl_benchmark

# Pick ESP-IDF install directory, this one for v4.4.2 in VisualGDB
. /mnt/c/SysGCC/esp32/esp-idf/v4.4.2/export.sh


idf.py build flash -p /dev/ttyS20 -b 921600 monitor

Example Output

Note the default wolfSSL user_settings.h is configured by default to be the most compatible across the widest ranges of targets. Contact wolfSSL at support@wolfssl.com for help in optimizing for your particular application, or see the docs.

Compiled and flashed with idf.py build flash -p /dev/ttyS7 -b 921600 monitor:

Known Issues and Common Issues

Permission denied

Delete project directory build, .visualgdb and .vs directories. Ensure no other build process is using the same files in Windows, WSL, Visual Studio, VSCode, etc.

Example message:

-- Building ESP-IDF components for target esp32

Ensure wolfSSL is installed in the ESP-IDF or local project components directory.
