1. Download files

   $ git clone https://github.com/raspberrypi/pico-sdk

   $ git clone hhttps://github.com/FreeRTOS-kernel

   $ git clone https://github.com/wolfssl/wolfssl

2. Define path

   $ export PICO_SDK_PATH=/your/pico-sdk/path

   $ export FREERTOS_KERNEL_PATH=/your/FreeRTOS-kernel/path

   $ export WOLFSSL_ROOT=/your/wolfssl-root/path

3. cmake and make

   $ cd wolfssl-examples/RPi-Pico

   $ cmake -DPICO_BOARD=pico_w -DWIFI_SSID=your-wifi-ssid

   • DWIFI_PASSWORD=your-wifi-password
   • DTEST_TCP_SERVER_IP=ip-addr
   • DUSE_WIFI=ON
   • DDATETIME=yymmddhhmmss .

   $ make

DATETIME is for certificate validity check. Not need to be very acurrate.
