目前还是一个学生,项目不会做,只能写一些学习笔记,没有什么经验(可能一些自己判断的有一定错误,内容仅作为参考),
个人认为一个健全的项目首先就需要一个bootloader,所以就浅浅记录一下自己使用rtthread studio配置qboot和app工程的制作过程.
使用工具:rtthread studio
移植qboot工程过程
1.创建工程
1.1 创建qboot的项目工程1.2 浅跑一下试试2.开始配置spi的外部flash – w25q16 (这里使用spi1,可根据具体调整)
2.1 spi硬件连接2.2 在rtthread setting内开启spi2.3 在board.h内开启使用spi12.4 CubeMX setting内配置spi2.5 CubeMX setting内配置芯片时钟2.6 添加挂载spi的代码
//****************************************
//注意这里括号显示就没了 自己包含一下头文件
//****************************************
//这里添加 rtthread.h
//加上 大于小于括号
#include
#include "drv_spi.h"
#include "spi_flash_sfud.h"
//挂载spi
int rt_hw_spi_flash_init(void)
{
__HAL_RCC_GPIOB_CLK_ENABLE(); //片选引脚为PB14
rt_hw_spi_device_attach("spi1", "spi10", GPIOB, GPIO_PIN_14); //片选引脚为PB14
if (RT_NULL == rt_sfud_flash_probe("w25q16", "spi10"))
{
return -RT_ERROR;
}
return RT_EOK;
}
INIT_DEVICE_EXPORT(rt_hw_spi_flash_init);
2.7 成功创建spi和w25q163.使用fal设置分区
3.1 添加软件包3.2 board.h 里定义define BSP_USING_ON_CHIP_FLASH
3.3 配置Fal3.4 添加路径 因为运行提示找不到fal_cfg.h的路径在此处运行后,会发现如下错误:(在这个地方有较多的解决方法,但是有的方法在到后面在使用后续的ota升级的时候,会擦除到app区域,具体我也不懂…….)
3.5 出现错误解决方法:(将如下代码 全部替换 到 drv_flash_f4.c 文件)

3.7 可以看见分区已经成功了4.开始添加qboot
4.1 添加qboot4.2 配置qboot 把没用上的都关了4.3 qboot运行成功(上面打印问题把main函数里面打印去掉就好了)移植app工程过程
1.创建工程在main中添加如下
#include "stm32f4xx_hal.h"
/*app partition begin address*/
//app分区的地址
#define RT_APP_PART_ADDR 0x08020000
static int ota_app_vtor_reconfig(void)
{
#define NVIC_VTOR_MASK 0x3FFFFF80
/* Set the Vector Table base location by user application firmware definition */
SCB->VTOR = RT_APP_PART_ADDR & NVIC_VTOR_MASK;
return 0;
}
INIT_BOARD_EXPORT(ota_app_vtor_reconfig);
int F4_clock_information(void)
{
LOG_I("System Clock information");
LOG_I("SYSCLK_Frequency = %d", HAL_RCC_GetSysClockFreq());
LOG_I("HCLK_Frequency = %d", HAL_RCC_GetHCLKFreq());
LOG_I("PCLK1_Frequency = %d", HAL_RCC_GetPCLK1Freq());
LOG_I("PCLK2_Frequency = %d", HAL_RCC_GetPCLK2Freq());
return RT_EOK;
}
INIT_DEVICE_EXPORT(F4_clock_information);
2.修改 \linkscripts\STM32F407ZG\link.lds 内的起始地址
2.1 将0x08000000改为你的app分区的地址3.成功运行结果
3.1 最基本的app已经成功运行附带一个工程文件
https://github.com/Letian-stu/Stm32F407-rtos-qboot-app-prj
Stm32F4-spi-qboot-mini
- 对qboot的移植;
- 分区设置;
- 可以使用ymodem_ota;
