目前還是一個(gè)學(xué)生,項(xiàng)目不會(huì)做,只能寫(xiě)一些學(xué)習(xí)筆記,沒(méi)有什么經(jīng)驗(yàn)(可能一些自己判斷的有一定錯(cuò)誤,內(nèi)容僅作為參考),

個(gè)人認(rèn)為一個(gè)健全的項(xiàng)目首先就需要一個(gè)bootloader,所以就淺淺記錄一下自己使用rtthread studio配置qboot和app工程的制作過(guò)程.

芯片使用:STM32F407ZG

使用工具:rtthread studio

移植qboot工程過(guò)程

1.創(chuàng)建工程

2.開(kāi)始配置spi的外部flash – w25q16 (這里使用spi1,可根據(jù)具體調(diào)整)

//****************************************
//注意這里括號(hào)顯示就沒(méi)了 自己包含一下頭文件
//****************************************

//這里添加 rtthread.h
//加上 大于小于括號(hào)
#include 
#include "drv_spi.h"
#include "spi_flash_sfud.h"

//掛載spi
int rt_hw_spi_flash_init(void)
{
    __HAL_RCC_GPIOB_CLK_ENABLE();		//片選引腳為PB14
    rt_hw_spi_device_attach("spi1", "spi10", GPIOB, GPIO_PIN_14);		//片選引腳為PB14

    if (RT_NULL == rt_sfud_flash_probe("w25q16", "spi10"))
    {
        return -RT_ERROR;
    }
    return RT_EOK;
}
INIT_DEVICE_EXPORT(rt_hw_spi_flash_init);	

3.使用fal設(shè)置分區(qū)

在此處運(yùn)行后,會(huì)發(fā)現(xiàn)如下錯(cuò)誤:(在這個(gè)地方有較多的解決方法,但是有的方法在到后面在使用后續(xù)的ota升級(jí)的時(shí)候,會(huì)擦除到app區(qū)域,具體我也不懂…….)

解決方法:(將如下代碼 全部替換 到 drv_flash_f4.c 文件)

2.修改 \linkscripts\STM32F407ZG\link.lds 內(nèi)的起始地址

3.成功運(yùn)行結(jié)果

附帶一個(gè)工程文件
