U盘升级固件，STM32F407同时挂载U盘和Flash，写U盘出问题

发布于 2023-04-13 18:50:17 浏览：1180 订阅该版

目的是通过U盘和OTA实现固件升级，卡在u盘读写上了：
1.参考https://blog.csdn.net/weixin_41738023/article/details/113390312 进行U盘和Flash挂载。

2.用函数测试`void readwrite(const char* filename)`出现`CBW size error
usb mass_storage read failed`问题。   `length = write(fd, test_data, sizeof(test_data));`这一步挂的。

```c
#define TEST_FN     "/udisk/test_usbh.c"
void readwrite(const char* filename)
{
    int fd;
    int index, length;
		rt_kprintf("write data come 1\n");

fd = open(TEST_FN, O_WRONLY | O_CREAT | O_TRUNC, 0);
    if (fd < 0)
    {
        rt_kprintf("open file for write failed\n");
        return;
    }

rt_kprintf("write data come 2\n");
		
    for (index = 0; index < sizeof(test_data); index ++)
    {
        test_data[index] = index + 27;
    }
		
		rt_kprintf("write data come 3\n");

length = write(fd, test_data, sizeof(test_data));
		
		rt_kprintf("write data come 3.5\n");
    if (length != sizeof(test_data))
    {
        rt_kprintf("write data failed\n");
        close(fd);
        return;
    }

close(fd);

rt_kprintf("write data come 4\n");
    fd = open(TEST_FN, O_RDONLY, 0);
    if (fd < 0)
    {
        rt_kprintf("check: open file for read failed\n");
        return;
    }
		
		rt_kprintf("write data come 5\n");

length = read(fd, buffer, sizeof(buffer));
    if (length != sizeof(buffer))
    {
        rt_kprintf("check: read file failed\n");
        close(fd);
        return;
    }

rt_kprintf("write data come 6\n");
    for (index = 0; index < sizeof(test_data); index ++)
    {
        if (test_data[index] != buffer[index])
        {
            rt_kprintf("check: check data failed at %d\n", index);
            close(fd);
            return;
        }
    }

rt_kprintf("usb host read/write udisk successful\r\n");

close(fd);
}
```

3.ls能看到U盘文件里的内容，如下是启动，打印的测试结果：

4.看许多问答，提示`static int drv_pipe_xfer(upipe_t pipe, rt_uint8_t token, void *buffer, int nbytes, int timeouts)`函数有问题，请求如何解决？
根据 https://blog.csdn.net/weixin_41738023/article/details/113390312   做过修改。
不修改一测试就崩溃。

```c
static int drv_pipe_xfer(upipe_t pipe, rt_uint8_t token, void *buffer, int nbytes, int timeouts)
{
    int timeout = timeouts;
	
		int res = 0;

while (1)
    {
        if (!connect_status)
        {
            return -1;
        }
        rt_completion_init(&urb_completion);
        HAL_HCD_HC_SubmitRequest(&stm32_hhcd_fs,
                                 pipe->pipe_index,
                                 (pipe->ep.bEndpointAddress & 0x80) >> 7,
                                 pipe->ep.bmAttributes,
                                 token,
                                 buffer,
                                 nbytes,
                                 0);
				
				 rt_thread_mdelay(1);//wxm 1
        //rt_completion_wait(&urb_completion, timeout);

				{
						RT_DEBUG_LOG(RT_DEBUG_USB, ("rt_completion_wait failed = %d\r\n", res));
						connect_status = RT_FALSE;
					
						return -RT_ETIMEOUT;		
				}
				
				
        rt_thread_mdelay(50);//wxm 1
        if (HAL_HCD_HC_GetState(&stm32_hhcd_fs, pipe->pipe_index) == HC_NAK)
        {
            RT_DEBUG_LOG(RT_DEBUG_USB, ("nak\n"));
            if (pipe->ep.bmAttributes == USB_EP_ATTR_INT)
            {
                rt_thread_delay((pipe->ep.bInterval * RT_TICK_PER_SECOND / 1000) > 0 ? (pipe->ep.bInterval * RT_TICK_PER_SECOND / 1000) : 1);
            }
            HAL_HCD_HC_Halt(&stm32_hhcd_fs, pipe->pipe_index);
            HAL_HCD_HC_Init(&stm32_hhcd_fs,
                            pipe->pipe_index,
                            pipe->ep.bEndpointAddress,
                            pipe->inst->address,
                            USB_OTG_SPEED_FULL,
                            pipe->ep.bmAttributes,
                            pipe->ep.wMaxPacketSize);
            continue;
        }
        else if (HAL_HCD_HC_GetState(&stm32_hhcd_fs, pipe->pipe_index) == HC_STALL)
        {
            RT_DEBUG_LOG(RT_DEBUG_USB, ("stall\n"));
            pipe->status = UPIPE_STATUS_STALL;
            if (pipe->callback != RT_NULL)
            {
                pipe->callback(pipe);
            }
						
						connect_status = RT_FALSE;//wxm
						
            return -1;
        }
        else if (HAL_HCD_HC_GetState(&stm32_hhcd_fs, pipe->pipe_index) == URB_ERROR)

        else if(URB_DONE == HAL_HCD_HC_GetURBState(&stm32_hhcd_fs, pipe->pipe_index))
        {

            pipe->status = UPIPE_STATUS_OK;
            if (pipe->callback != RT_NULL)
            {

            {
                return size;
            }
            else if (pipe->ep.bEndpointAddress & 0x00)
            {
                return size;
            }
            return nbytes;
        }

continue;
    }
}
```

5.可否出个例程，同时挂载U盘和Flash,通过U盘和OTA实现固件升级啊？
根据文章:   https://blog.csdn.net/ShenZhen_zixian/article/details/121101799  出现如下问题
```c
static int ota_usb_download_entry(void* parameter)
{
    DIR *dirp;
    static size_t update_file_total_size, update_file_cur_size;
    static const struct fal_partition * dl_part = RT_NULL;
    static int fd;
    //static rt_uint8_t buf[1024];
	....
```

打印如下：
```
msh /udisk>ota_usb_start
msh /udisk>
msh /udisk>
msh /udisk>
msh /udisk>Default save firmware on download partition.
Warning: usb has started! This operator will not recovery.

[31m[E/ota_usb] Firmware download failed! Partition (download) write data error![0m
[31m[E/ota_usb] download rtthread.rbl file failed[0m
```

6.再补充个测试的问题，如上u盘格式是FAT32，接下来用电脑右键将U盘格式化为NTFS，同样用Readwrite进行测试，可以成功，ls能看到文件test_usbh.c，但是插电脑上看不见。

```
msh />readwrite
write data come 1
write data come 2
write data come 3
write data come 3.5
write data come 4
write data come 5
write data come 6
usb host read/write udisk successful

msh />ls
Directory /:
udisk               <DIR>                    
test                <DIR>                    
msh />
msh />cd udisk
msh /udisk>ls
Directory /udisk:
test_usbh.c         120
```

7.往回测试，发现问题应该还是出在读写U盘上，目前无论用4.0.X还是最新版本，用readwrite测试都会挂住，用的F407的开发板。
