This blog entry aims to familiarize readers with locating an active UART on a target system, how to approach a UBoot console, and ultimately how to leverage both of these components to extract the flash memory from our target. After reading this, readers will be familiar with the screen utility the depthcharge python3 libraries.

This post reviews some of the tools needed when setting up a lab for reverse engineering embedded systems. There will be two sections, one for hardware tools and one for software tools. After reading this blog post, the reader should know what is needed to set up an introductory lab for reverse engineering embedded systems and firmware images.

In previous posts, we've gone over how to tear down Arcade cabinets containing SPI Flash as well as how to dissect the data that was extracted from the Rom. With this next series of posts, I'd like to take the concepts we talked about on those platforms and demonstrate them on a more popular platform With this post our goal will be to extract the firmware from the platform and locate and type of debugging if possible (UART,JTAG,etc). We will explore multiple ways of attempting to extract the filesystem and outline the steps taken for each method.
