创建bootloader工程

使用vscode workbench for zephyr创建工程

创建完成如下：

工程添加板级信息

1.修改默认设备树 zephyrproject\zephyr\boards\st\stm32f407_alientek
stm32f407_alientek.dts加入：
zephyr,code-partition = &slot0_partition;
&flash0 {…};

2.添加bootloader工程板级配置
zephyrproject\bootloader\mcuboot\boot\zephyr\boards
增加 stm32f407_alientek.overlay

/{chosen{zephyr,code-partition=&boot_partition;};};

增加 stm32f407_alientek.conf

# 禁用自动计算，手动设置最大镜像扇区数（根据你的分区大小调整） CONFIG_BOOT_MAX_IMG_SECTORS_AUTO=n CONFIG_BOOT_MAX_IMG_SECTORS=16CONFIG_LOG=y CONFIG_MCUBOOT_LOG_LEVEL_DBG=y

3.编译bootloader工程，烧录。
日志：

创建app工程

参考以前的文章，不再详细说明。

1.修改工程配置

#Enable Zephyr application to be booted by MCUbootCONFIG_BOOTLOADER_MCUBOOT=y#CONFIG_BOOT_UPGRADE_ONLY=y #当 mcuboot 发现 slot1 里有新固件时，直接把新固件覆盖到 slot0 并运行，不需要做可回滚升级#Use thedefaultMCUBoot PEM keyfile(BOOT_SIGNATURE_KEY_FILE)CONFIG_MCUBOOT_SIGNATURE_KEY_FILE="bootloader/mcuboot/root-rsa-2048.pem"

2.修改vscode launch脚本

3.编译，烧录。
