Reverse Engineering the OMNIVISION OS12D40 Driver
– In Part 6 of our series, we structured a theoretical discussion regarding the devices, how they communicate, and the hardware elements that enable this. See Full Article
Techniques for Setting up Peripherals via PIO and DMA
– In Part 5 of our series, we focused our efforts on understanding how the firmware was structured. In doing so, we analyzed the folder with the system executables and delved into the various configuration files. See Full Article
Exploring the Operating System of Reolink RLC-810A
– In Part 4 of our series, we focused on the file system and before concluding, we were able to extract files from two UBIFS images contained within the firmware. Here in Part 5, we will try to better understand the structure of the root file system by introducing some basic concepts of the operating system used by Reolink RLC-810A, namely Linux.

Understanding the UBI File System in Embedded Devices
– In Part 3 of our series, we explored the hardware device elements of the Reolink RLC-810A ― focusing on the NAND memory. We continue with Part 4 of our exploration into an IP camera firmware through introducing the concept of a file system. Furthermore, we will explore the technical reasons for choosing the UBI File System (UBIFS), a file system used especially for a category of mass storage, and … See Full Article
Dissecting Reolink RLC-810A Hardware: A Detailed View
– Now that we know how device booting works, let’s try to extract some parts from the firmware that we downloaded in Part 1 of our series. Here, we are interested in two main sections: the Linux kernel (which takes care of booting the device services) and the flattened device tree (which allows the kernel to know the hardware configuration a priori without inspecting each device).

Booting an Embedded OS: the Booting and U-Boot Phase
– In the first post, we introduced embedded devices and started to scour through and extract information from Reolink IP camera firmware. At the end of the post, we ran Binwalk, which showed various types of files such as Flattened Device Tree, uImage Header, and UBI File System. See Full Article
Introduction to Firmware Analysis of a Reolink IP Camera
– Embedded devices continue to increase in popularity and one category, in particular, that has become en vogue as of late is the Internet of Things (IoT). The emergence of these next generation technologies has driven the home automation evolution from simple light bulbs to cloud-connected printers, smart refrigerators, etc. See Full Article
