When programming the Arduino using an ISP, the bootloader on the board will be lost, so it is necessary to re-burn the bootloader. Since we need to burn the bootloader, what exactly is a bootloader? As you might expect, a bootloader is indeed a program, and since it needs to be burned into the microcontroller, … Read more
ObjectiveThe purpose of this document is to develop a fully compatible bootloader based on the basic requirements for firmware upgrades (local upgrade via USB) for STM32.USB Upgrade Process Detect if a USB drive is present during power-up; If a USB drive is detected, check if there is an upgrade file with the corresponding … Read more
Do you really understand the boot process of embedded systems? 😏😏😏 The boot process of an embedded system refers to the entire sequence of events from the power-off state to the normal operating state when the system is powered on. In embedded systems, the design and implementation of the boot process are crucial for the … Read more
Five years ago, a new adjustable ECU/ECM claimed to be “unhackable” and dominated the market at that time; it was the GM E41 ECM Services (L5P). This ECU/ECM first appeared on the L5 Peter Max truck in 2017, and many believed that such ECUs/ECMs could not be hacked or tuned. As experts from the external … Read more

01 What is a BootLoader? It is a boot program, which is the first program to execute after hardware reset. Its main job is to initialize the environment for the operating system to run, such as memory, timers, buffers, etc. Once this is done, it loads the operating system’s code into memory, and then the … Read more
