Fatfs Error! w25Q64

lxd7410

去掉SD卡，挂载w25Q64，烧入程序后显示Fatfs Error!
问题应该在exf_getfree("1",&total,&free)函数返回错误代码！不解 求助！！谢谢

站台雨

是不是Flash的那个失败？你的W25Q64芯片有没有格式化？在操作Flash之前需要先格式化Flash

正点原子

先 格式化SPI FLASH试试

        结果一样！！！ 显示Fatfs Error!
        SPI_Flash_Erase_Chip();//????????
f_mkfs("1:",1,4096);//??????FLASH
while(exf_getfree("1",&total,&free))//????Flash??×??????????à????
{
LCD_ShowString(60,150,200,16,16,"Fatfs Error!");
delay_ms(200);
LCD_Fill(60,150,240,150+16,WHITE);//????????   
delay_ms(200);
LED0=!LED0;//DS0????
}
