 ## Introduction
 
 This article is part of the “First Steps with ESP32 and NuttX” series. A series whose objective is to present an overview of the NuttX Operating System and to provide instructions for using NuttX on ESP32.
 
-The [first part](/blog/getting-started-with-esp32-and-nuttx) of the series showed how to prepare the environment, compile and build the Operating System (NuttX) until uploading the firmware to the SoC (ESP32).

 This is the second part and will demonstrate how to run the famous “Hello World” from the Embedded Systems world, i.e., an application that blinks a LED. The evaluation board used here is a DevKit v1 and the built-in LED will be used for convenience. If your DevKit does not come with a built-in LED, just connect an LED to pin 2 in series with a resistor as it will be briefly discussed in the execution section.

 [Zephyr OS](https://www.zephyrproject.org/) is an open-source, scalable, and adaptable real-time operating system (RTOS) for multiple hardware platforms, including [Espressif’s](https://www.espressif.com/) SoCs ESP32, ESP32S2, ESP32C3, and ESP32S3. Zephyr OS provides a wide range of features for embedded systems development, including support for generating and analyzing core dumps on unrecoverable software errors.

 Those who develop IoT applications based on Zephyr OS often need to optimize the communication performance. It can be done by tweaking the Wi-Fi network stack parameters. However, how do you evaluate the resulting changes and find the most suitable configuration? In this article, we will overview a method to optimize communication performance by using the `iperf` and `zperf` tools.

 ## Developing a Project with Existing Applications
 
 The process of building an application in NuttX - whether it is a custom application or one that already exists and targets other operating systems - follows the principles of the NuttX build system. Although the NuttX documentation covers aspects of the application compilation process in various articles and documents, we will delve deeper into some of these options in this article.
 
-For those who are not familiar with NuttX, I recommend reading the article [Getting Started with NuttX and ESP32]({{< ref "blog/nuttx-getting-started/index.md" >}}) or referring to the [*Getting Started*](https://nuttx.apache.org/docs/latest/quickstart/index.html) section in the official NuttX documentation. I would like to highlight NuttX's great advantage: being a POSIX-compliant system allows for easy integration of many applications into the system. About that, there's an old saying:

 Those acquainted with the ESP32 system-on-chip (SoC) family know the complexity involved in analyzing its booting process. From navigating the embedded ROM bootloader, facilitated by comprehensive tooling, to initiating the 2nd stage bootloader, which subsequently launches the user application. The procedure deviates significantly from the the straightforward "jump-to-reset-vector" way of starting the user program, as we can see on the ARM architecture.

 Embedded systems can be quite complex, depending on the architecture, application size and nature. Even for an experienced embedded developer, understanding the interplay of threads, interrupts, and multiple processes that run in a large application can be challenging. We humans are (mostly) visual by nature, and having the means to *visualize* what is happening in a given system can really open up possibilities. Without the right tools we are often in the dark, quite literally.
