qboot firmware check fail. partition "download" infomation check fail

使用qboot软件包制作bootloader

为了使bootloader尽量小，对内核及其组件进行了如下配置
线程间通信只用选择这两个：
为了方便调试，下面这项配置成这样：
组件中除了这两项其他都不选：
这个msh shell其实占用rom挺多的。我们用console打印调试信息，但是可以不用shell, shell只是一些命令集
网络组件全部不用，这些子菜单点进去，确认都没有选上！
配置qboot
开发板上红色灯是E7，低电平点亮，所以这里running status led pin设置为71，led on level设置为0。
必须要开启片内flash
下载软件包并编译
运行pkgs --update后，会自动下载qboot及其依赖包
下载完成后，在board/ports/fal目录下，添加如下源文件（把其他文件删掉，只保留SConscript）
fal_cfg.h:

#ifndef _FAL_CFG_H_
#define _FAL_CFG_H_

#include <rtconfig.h>
#include <board.h>

注意RT_APP_PART_ADDR这个宏，这是app跳转地址。这里分了64k给bootloader
drv_fal_init.c:

#include <rtthread.h>

#ifdef PKG_USING_FAL

#include <fal.h>
extern int fal_init(void);
INIT_COMPONENT_EXPORT(fal_init);

#endif

修改main.c

int main(void)
{
    /* set LED0 pin mode to output */
    return RT_EOK;

把编译优化级别设置为Os，修改rtconfig.py文件：
在这里插入图片描述

运行scons编译，我这编译完了之后，有36kb。

运行效果
因为app区 download区和factory区都没有固件，所以一直重启（等待时间是默认的5秒）：

制作带ota升级功能的app

使能ymodem和fal
board/ports/fal目录中的所有源文件内容保持和bootloader中的一样。
app的地址偏移是64k，必须保证以下两点才能跳转成功

修改链接脚本
重新设置中断向量表地址
main.c中添加如下代码段：

/* 将中断向量表起始地址重新设置为 app 分区的起始地址 */
static int ota_app_vtor_reconfig(void)
{
    #define NVIC_VTOR_MASK 0x3FFFFF80
    #define RT_APP_PART_ADDR 0x08010000
    /* 根据应用设置向量表 */
    SCB->VTOR = RT_APP_PART_ADDR & NVIC_VTOR_MASK;

    return 0;
}
INIT_BOARD_EXPORT(ota_app_vtor_reconfig);

为了使用ymodem传输固件，还需要在applications目录添加如下源文件

编译完了之后，用固件打包器打包
传输新固件
1. 输入ymodem_start
2. 选择.rbl文件
  
  注意终端工具用的是xshell
  传完了之后自动重启：
