Introduction The Zephyr Project Real-Time Operating System (https://zephyrproject.org/) or simply “Zephyr” is an increasingly popular real-time operating system as it natively supports over 450 boards and countless peripherals. When starting any embedded software project, the first priority is to begin from a known baseline. This may include cloning a repository from source control (embedded Linux … Read more
Recently, I encountered several clients who are developing their products on the Jetson TX2. When they reached the mass production stage, they discovered issues—because the Jetson TX2 version has technical updates at different times. As a result, the clients overlooked this issue and found that the software (mainly some drivers) or hardware they worked hard … Read more
