MCUboot Boot Modes Overview

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

Compression of Interrupt Signals in MCUs – Secondary Interrupt Lookup

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
