请问一下用spi读取flash时好时坏是怎么回事呢？

flash：W25Q16DV

代码：

#include "drv_spi.h"
#include <rtdevice.h>
#include "spi_flash_sfud.h"
#define SPI_NAME "spi1" //spi 接口名
#define CS_GPIO GPIOB //片选GPIO组 stn32
#define CS_PIN GPIO_PIN_14 //片选GPIO脚 stm32
#define SPI_DEV_NAME "spi10" //挂在在spi总线上的设备名
#define FLASE_NAME "W25Q16" //flash设备名
#define FS_NAME "elm" //文件系统
#define ROOT_PATH "/flash1" //文件系统的根目录
int w25q_init(void){
rt_hw_spi_device_attach(SPI_NAME, SPI_DEV_NAME, CS_GPIO, CS_PIN);
rt_hw_us_delay(100);
if(rt_sfud_flash_probe(FLASE_NAME, SPI_DEV_NAME)){
rt_kprintf("sfud flash probe success\n");
return RT_EOK;
}
else{
rt_kprintf("sfud flash probe fail\n");
return RT_ERROR;
}
}
INIT_COMPONENT_EXPORT(w25q_init);
int dfs_mount_init(void){
dfs_mkfs(FS_NAME, FLASE_NAME);
if(dfs_mount(FLASE_NAME, ROOT_PATH, FS_NAME, 0, 0) == 0){
rt_kprintf("dfs_mount success\n");
return RT_EOK;
}
else{
rt_kprintf("dfs_mount fail\n");
return RT_ERROR;
}
}
INIT_COMPONENT_EXPORT(dfs_mount_init);

输出：

[I/SFUD] Warning: Read SFDP parameter header information failed. The W25Q16 is not support JEDEC SFDP.
[I/SFUD] Find a Winbond W25Q16BV flash chip. Size is 2097152 bytes.

我不使用代号，使用sf工具操作flash，读是没有问题的，但是写和删除有问题，问题时好时坏，就像github上说的可能是读切换日佥楽题
