All sample applicatons in Zephyr, using the ENC28J60 driver, set the ETH_ENC28J60_0_GPIO_PIN Kconfig variable to 19. However, in the Kconfig.enc28j60 file this variable is set to 24. That default value, 24, was used only during the first iterations of this driver and never used again. In this patch, we set the Kconfig variable to 19 and simplify project configuration files by removing one line.

mbedTLS DTLS client #################### Overview ======== This sample code shows a simple DTLS client using mbed TLS on top of Zephyr Requirements ============ Building and running ==================== Follow the steps for testing :ref:`networking with Qemu <networking_with_qemu>`. Obtain the mbed TLS code from: https://tls.mbed.org/download/start/mbedtls-2.3.0-apache.tgz and put it in a well known directory on your Linux machine, this will be your server. change to that directory and compile the mbedTLS on your host machine: .. code-block:: console $ tar -xvzf mbedtls-2.3.0-apache.tgz $ cd mbedtls-2.3.0 $ CFLAGS="-I$PWD/configs -DMBEDTLS_CONFIG_FILE='<config-thread.h>'" make Assign the server IP address and start the DTLS server. .. code-block:: console $ sudo ip addr add 192.0.2.2/24 dev tap0 $ ./programs/ssl/ssl_server2 dtls=1 ecjpake_pw=passwd .. code-block:: console . Seeding the random number generator... ok . Bind on udp://*:4433/ ... ok . Setting up the SSL/TLS structure... ok . Waiting for a remote connection ... To stop the server use Ctrl-C and repeat steps described in f) every time QEMU gets terminated, due the Netwrok interface (tap) being restarted. From the application directory type .. code-block:: console $ make run This will result in Qemu running with the following output: .. code-block:: console . Seeding the random number generator... ok . Setting up the DTLS structure... ok . Connecting to udp 192.0.2.2:4433... ok . Setting up ecjpake password ... ok . Performing the SSL/TLS handshake... ok > Write to server: ok . Closing the connection... done On the server side you should see this .. code-block:: console . Performing the SSL/TLS handshake... hello verification requested . Waiting for a remote connection ... ok . Performing the SSL/TLS handshake... ok [ Protocol is DTLSv1.2 ] [ Ciphersuite is TLS-ECJPAKE-WITH-AES-128-CCM-8 ] [ Record expansion is 29 ] [ Maximum fragment length is 16384 ] < Read from client: 18 bytes read GET / HTTP/1.0 > Write to client: 143 bytes written in 1 fragments HTTP/1.0 200 OK Content-Type: text/html <h2>mbed TLS Test Server</h2> <p>Successful connection using: TLS-ECJPAKE-WITH-AES-128-CCM-8</p> . Closing the connection... done . Waiting for a remote connection ... ok . Performing the SSL/TLS handshake... failed ! mbedtls_ssl_handshake returned -0x7900 . Waiting for a remote connection ... Disregard the last handshake failed message, due the closing connection. If the server does not receive the messages, use a network traffic analyzer, like Wireshark. Reset the board.
