Stm32 bootloader Update firmware reboot IWDG independent watchdog

Symptom: The PCB board will restart directly from firmware soft reset to bootloader update Problem Reason: IWDG (independent watchdog) is turned on in the firmware, no dog is fed during firmware update, causing The count is counted to 0 and the watchdog resets reset. Problem solving: 1. Since the independent watchdog cannot be turned off once it is turned on, either feed the dog in the bootloader or do

Embedded bootloader development of nine----keyboard interrupt control LED lights (Tiny 6410) __ Embedded Arm-bootloader

bootloader role, why do you need bootloader?

1, the role of bootloader Simply put,BootLoader is a small program that runs before the operating system runs. With this applet, you can initialize the hardware device to bring the system's hardware and software environment to a suitable state to prepare for the final call to the operating system. The starting process for bootloader is divided into two stages st

Bootloader and kernel with startup process/compile bootloader/compilation kernel

Bootloader and kernel with the start-up process--------------------------------------------The ARM9 board has a Norflash chip that stores the basic Bootlader code, which is the 0 address where the CPU executes the code. The 4kRam space inside the CPU acts as the stack and data segment storage at this time. Because it is Samsung's own chip, so the hardware above can be implemented to Nandflash before the 4K code automatically copied to the Iram (the im

Relationship between Bootloader and kernel Image

Last night, I heard from my roommates about how to compile the Linux kernel. As a computer graduate, I don't know much about it. It's so depressing. After much understanding, we finally have a vague concept. In Linux, the kernel image is usually stored in Boot/grub or boot/Lilo. After a roommate's explanation, I have a rough idea about this image. But who will read this grub. conf? You do not know. Come and think about it in bed, bootloader! This must
