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. Another very interesting folder that we come across during our investigation is /lib, which includes all the libraries for executables and device … 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. Before tackling the analysis of a device driver, we need to focus on some hardware … 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 … See Full Article
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 … 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 … See Full Article
