Recently, someone asked how to test serial communication on an RK3588 that had Linux installed in our lab. I spent quite some time figuring it out, and below I will share the method with you.Tools required: Tabby (for SSH connection), RK3588, monitor.The prerequisite is that you have already installed the Ubuntu system to proceed with … Read more
This sub-chip and motherboardThe Boot ROM size of the Rockchip RK3588 chip is 32KB.The internal Boot ROM space of RK3588 is 32KB.The Boot ROM here is mainly used to store boot code and some basic initialization programs, playing a critical role during device startup, responsible for guiding the system to load a more complete operating … Read more
RK3588 Edge Computing Application: Detection of Walnut Ripeness Over the past 60 years, despite the discontinuation of neon tubes, many engineers still have a fondness for them. I created a simulated neon tube clock using 8 LCD screens to experience the aesthetic of retro elements and pay homage to classic designs from the past. The … Read more
The Rockchip platform typically updates the system through flashing. However, during some project evaluations, clients often require the ability to install the system. To enable USB installation on the RK platform, slight modifications to U-Boot are necessary to ensure that the U-Boot stage can properly load the uImage, uInitrd, and dtb files from the USB … Read more

After all, various sectors are eager to leverage AI for their services, and the field of image processing is no exception. Consequently, many have inquired whether RK3588 + DeepSeek is a viable option. To answer this: relying solely on … Read more
1. What is a Dielectric? A dielectric refers to a substance or space that can transmit force, energy, or information under specific conditions. In physics and engineering, dielectrics typically refer to solids, liquids, or gases that can transmit mechanical waves, electromagnetic waves, etc. For example, in acoustics, air, water, and solids can serve as media … Read more
In PCB (Printed Circuit Board) design, factors such as signal transmission stability and impedance matching are typically considered. Choosing the appropriate stacking scheme is crucial to meet design requirements. In certain cases, especially when designing six-layer boards, a special design scheme known as ‘pseudo eight-layer’ may be adopted. The ‘pseudo eight-layer’ actually refers to a … Read more
1. Problem Description A certain dashcam requires an external adapter for testing. During power-on testing, it was found to exceed standards, specifically at frequencies of 84MHz, 144MHz, and 168MHz. The cause of the excessive radiation needs to be analyzed, and corresponding countermeasures should be provided. The radiation test data is as follows:2. Analysis of Radiation … Read more
Capacitors play a crucial role in high-speed PCB design and are typically the most used components on a PCB. In PCBs, capacitors are generally categorized into filtering capacitors, decoupling capacitors, and energy storage capacitors. 1. Power Output Capacitors, Filtering Capacitors We usually refer to the capacitors in the input and output circuits of the power … Read more
