1. Introduction We have completed the foundational work, enabling us to have shell interaction capabilities, allowing arbitrary import and export of content in on-chip memory and SPIFLASH. Now we can enter the most critical phase: programming the image and loading it to run. First, we need to design the storage structure of the image in … Read more
In the world of embedded development, firmware updates are undoubtedly a headache but an unavoidable challenge. To allow the development board to program firmware, we need to reserve a set of dedicated interface pins. These pins are used in the factory to program the software, but once the product is shipped, we need to find … Read more
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

TIOBE has updated the programming language rankings for July 2016, and the biggest highlight this month is that the low-level assembly language has once again entered the top 10. Many people are surprised by the reasons that have led this low-level programming language to re-enter the top 10. They do not understand why a language … Read more
