<p dir="auto" style="color: #3a383f; margin: 0;" align="initial">This week, I majorly worked on successful intiialization of GRETH lwIP driver as verified using printf statements at various stages during the process, and running <code style='font-size: 90%; color: #18171d; word-wrap: break-word; border-radius: .25rem; background-color: #ececef; margin-top: 0; font-weight: inherit; white-space: break-spaces; word-break: break-all; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; overflow-wrap: break-word; padding: 0.125rem 0.25rem;'>telnetd01.exe</code> test from RTEMS lwIP package as well as trying out new approach of using 2 differently configured TTCP test executables and use one as transmitter and other as receiver, but this didn't seem to work as expected. The transmitter timed out too soon and communication didn't seem to be established. Considering the time constraints, I used anotehr approach, as suggested by <a href="https://gitlab.rtems.org/opticron" data-reference-type="user" data-user="4" data-container="body" data-placement="top" class="gfm gfm-project_member js-user-link" title="Kinsey Moore" style="color: #284779; background-color: #cbe2f9; border-radius: .25rem; padding: 0 2px;">@opticron</a> to use a UDP client which sends a message to GRETH with a static IP address, and this approach worked! I could use <code style='font-size: 90%; color: #18171d; word-wrap: break-word; border-radius: .25rem; background-color: #ececef; font-weight: inherit; white-space: break-spaces; word-break: break-all; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; overflow-wrap: break-word; padding: 0.125rem 0.25rem;'>tcpdump</code> to check the UDP packets being received by GRETH legacy driver, and also <code style='font-size: 90%; color: #18171d; word-wrap: break-word; border-radius: .25rem; background-color: #ececef; font-weight: inherit; white-space: break-spaces; word-break: break-all; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; overflow-wrap: break-word; padding: 0.125rem 0.25rem;'>netcat</code> to send custom UDP packets to GRETH legacy drievr and check their reception. For testing GRETH legacy drievr I used <code style='font-size: 90%; color: #18171d; word-wrap: break-word; border-radius: .25rem; background-color: #ececef; font-weight: inherit; white-space: break-spaces; word-break: break-all; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; overflow-wrap: break-word; padding: 0.125rem 0.25rem;'>telnetd02.exe</code> from RTEMS legacy networking package, and it also had an inbuilt command <code style='font-size: 90%; color: #18171d; word-wrap: break-word; border-radius: .25rem; background-color: #ececef; font-weight: inherit; white-space: break-spaces; word-break: break-all; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; overflow-wrap: break-word; padding: 0.125rem 0.25rem;'>netstats</code> for showing previous communication session's statistics. This showed proper statistics for the UDP communication as described above.</p>
