rt文件系统挂的w25q   读写一段时间之后文件就打不开了   重启板子又可以读出里边的文件了  有多个线程读写同一个文件  但是我加了信号量```   rt_uint32_t fd;

char buf[1024];
    rt_uint16_t i;
    rt_err_t res = RT_EOK;

struct dfs_fd files;
    rt_sem_take(&file_sem,RT_WAITING_FOREVER);
    codeNum = codeNum%TranRecodeMaxCount;
    res = dfs_file_open(&files,codeName,O_RDWR|O_CREAT);

if(res!=RT_EOK)
    {
        ttr_dbg("open-w codefile fail<br>");
        goto end;
    }

dfs_file_lseek(&files,56*codeNum);

sprintf(buf,"%08x,",codeNum);
    dfs_file_write(&files,buf,strlen(buf));

for(i=0; i<sizeof(code.startTime); i++)
    {
        sprintf(buf,"%02x",code.startTime*);
        dfs_file_write(&files,buf,strlen(buf));
    }
    dfs_file_write(&files,",",1);
    for(i=0; i<sizeof(code.endTime); i++)
    {
        sprintf(buf,"%02x",code.endTime*);
        dfs_file_write(&files,buf,strlen(buf));
    }
    dfs_file_write(&files,",",1);

sprintf(buf,"%02x",code.runMode);
    dfs_file_write(&files,buf,strlen(buf));
    dfs_file_write(&files,",",1);

sprintf(buf,"%02x",code.runstate);
    dfs_file_write(&files,buf,strlen(buf));
    dfs_file_write(&files,",",1);

sprintf(buf,"%02x",code.runWaring);
    dfs_file_write(&files,buf,strlen(buf));
    dfs_file_write(&files,",",1);

for(i=0; i<sizeof(code.Reserved); i++)
    {
        sprintf(buf,"%02x",code.Reserved*);
        dfs_file_write(&files,buf,strlen(buf));
    }
    dfs_file_write(&files,",<br>",2);

end:
    dfs_file_close(&files);
    rt_sem_release(&file_sem);
    return 1;```
