一、Bootloader
1、Bootloader生成
官方网站：http://iot.rt-thread.com
官方文档：https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/application-note/system/rtboot/an0028-rtboot
新建产品->固件升级->生成Bootloader：
将会生成bin固件发送到邮箱并下载：
2、Bootloader烧录
配置工程、Target->Production Programming（JLINK方式）：
由于此时app分区还没有对应的app程序，所以会卡住：
二、Application
1、链接文件修改
修改程序链接脚本中ROM的起始地址和大小：
2、中断向量表地址偏移
由于App分区的起始地址为0x08020000（根据实际情况），需要修改链接脚本和中断向量的跳转地址；
注意：rt-thread/src/components.c->rtthread_startup为初始化函数，初始化完毕进入main。
修改中断向量表位置（board.c）：
RT_WEAK void rt_hw_board_init()
{
// 中断向量表偏移
SCB->VTOR = ((uint32_t)0x8020000);
... ...
3、添加固件版本信息
在 main 函数中添加版本信息（用于区别APP分区）：
#define APP_VERSION "1.0.0"
int main(void)
{
rt_kprintf("/* ---------Application--------- */\n");
rt_kprintf("The current version of APP firmware is %s\n", APP_VERSION);
... ...
4、FLASH及分区配置
SFUD（全称 Serial Flash Universal Driver）是一款开源的串行 SPI Flash 通用驱动库;
FAL：Flash 抽象层。
使能组件：
修改board.h:
#define BSP_USING_ON_CHIP_FLASH
#define BSP_USING_SPI2
添加fal_config：
// 修改fal_cfg.h：

rt_kprintf("rt_sfud_flash_probe failed!\n");
}
// 初始化FAL

5、执行OTA升级
制作固件包
https://codeload.github.com/RT-Thread-packages/ota_downloader/zip/refs/tags/1.0.0
打开资源所在目录：
打包固件：
注意：OTA只会增量升级，固件版本必须大于当前app分区版本号才可以触发。
