This bootloader example can jump to 2 different applications. The FLASH memory (64KB) is splitted into multiple partitions. The first partition (20KB) is for the bootloader. The second partition is for the Appl
固件在线升级 BootLoader 的主要功能是加载主程序,但为了支持在线升级,它需要实现对 Flash 的擦除和写入功能。通过网络(如 WiFi、以太网)或串行接口(如 UART、CAN),将新固件下载到设备中并写入 Flash,完成程序的更新。 分区存储管理 在复杂的应用中,可能会使用 Flash 的不同分区存储多个固件版本或配置文件。Flash ...

We already learned what a bootloader is and why it is needed in this article. Today we will start developing our own bootloader. For this particular example, we will be using STM32F411 discovery board and FT2232H

If we forego the option to boot from RAM, we can hold BOOT1 low and add a switch or jumper to BOOT0. If BOOT0 is high after a reset, the processor boots from system memory which, as delivered, means the bootloader. Holding the pin low boots from the on-board user flash and execut...

which uses theU-Boot SPLas the first-stage bootloader, andU-Bootitself as the second stage bootloader. It only works when the first stage bootloader is theArm Trusted Firmware, also calledTF-A. You can get more details about the different possible boot chains on STM32MP1 onthis Wiki page...
