Source | Renesas Embedded Encyclopedia With the development of embedded systems, the demand for code upgrade functionality in products is increasing. Code upgrades can achieve goals such as supporting new features and fixing bugs. The essence of a code upgrade is the process of erasing and writing to the on-chip flash memory (mainly code flash). … Read more
1. Overview of MCUboot MCUboot is an open-source, secure bootloader designed specifically for microcontrollers (MCUs). It was originally part of the Mynewt project and has since become the standard bootloader for RTOS such as Apache NuttX and Zephyr. MCUboot provides a secure firmware update mechanism and supports multiple boot modes, ensuring that the system can … Read more
In ARM-based MCU subsystems, there are only 240 peripheral interrupts available. Therefore, for a large number of interrupts, a secondary lookup is necessary. The cost of this approach is that it cannot achieve timely system responses, as it requires time to read the status registers.This article introduces the method of compressing interrupt signals and the … Read more

FPGA: The Communication ‘Transformers’ Born for Extreme Environments The ‘Rigidity’ Pain of Emergency Communication In the event of natural disasters or emergencies, communication infrastructure often bears the brunt. Base stations collapse, fiber optic cables are cut. Conventional communication methods fail instantly. At this moment, the communication capability of rescue teams directly affects the efficiency of … Read more
In embedded development, precise delay control is crucial for many applications, especially in scenarios such as sensor sampling and protocol timing control. Traditional methods of implementing delays often rely on simple for loops; however, this approach not only lacks precision but also wastes a significant amount of CPU resources during long delays. To improve delay … Read more
