Porting FatFs to LPC5411 with SPI throws a FR_NO_FILESYSTEM error?

puddletowntom — Fri, 25 May 2018 08:26:59 GMT

I have been following the tutorial attached below for setting up the LPC5411 with an SD card. I was able to write and read to the SD card as a basic data logger, but I haven't got the FAT file system working.

I m now stuck on an issue which involves executing the f_open() function. Its fails after returning the FR_NO_FILESYSTEM (no valid FAT volume) error. I tried formating the SD card in a number of variations of the FATFS but to no luck. Looking deeper into this problem, it seems as though the issue is caused when checking the boot record signature in the ff.c file. eg if(ld_word(fs->win + BS_55AA) != 0xAA55) return 3;

When the boot record signature does not result with the value 0xAA55 it returns a 3 which in turn results in the no valid FAT volume error (FR_NO_FILESYSTEM ).

Does anybody know if the architecture of the LPC5411 is little endian or big endian? I couldnt find this on the datasheet. Reading the elm chan blog there is information about the FATFS being little endian and the need for conversion if using big endian architecture.

Hi Ronan,

Can you upload your SD project which can write and read the basic SD card data?

Then, I will try to help you to add the Fatfs file for you.

Have a great day,
Kerry

Hi Kerry,

Is there a way to attach files on the forum?

Thank you,

Hi Ronan,

Please attache your project, you can use the advanced editor, there will have the attachment button.

Have a great day,

Hi Kerry,

Sorry, I didn't see that option. I have attached the files below. In addition one thing I noticed yesterday was that I could read and write to the ScanDisk(EDGE) 4GB microSD HCI card. However using a ScanDisk(Video Buffer) 4GB microSD HCI card, the card would not retain the information I wrote to it. Not sure why this is but I will investigate it.

Thank you,

Ronan

Hi Ronan,

It's better give me the project instead of the .c file, then I can debug your code directly, and porting the fatfs file, it will save both you and my time, please also tell me what the IDE you are using?

Have a great day,
Kerry

Hi Kerry,

I was just wondering, would it be possible to get an idea of the time frame that you can get back to me about this issue.

Thanks,

Ronan

Hi Kerry,

I have attached the project file. The IDE I m using is MCUXpresso.

Hi Kerry,

Sorry to be bothering you again, but I was wondering, have you had a chance to look at my code?

Thank you,

Hi Ronan,

Sorry for my later reply, I am checking your code these days. I still need time to check it in details about the fatfs porting and testing.

Please keep patient, thank you!

Have a great day,

Hi Kerry,

I just want to let you know that I m a little under pressure with getting the file system working for my application. I am trying to reach a deadline which uses the NXP microcontroller next week. It would be greatly appreciated if you could get back to me at some stage tomorrow.

Thank you,

Ronan

Hi Ronan，

On my side, I have a LPC54114 SPI SD fatfs project, which is used for this lpc54114 board, this board already have the SD card hardware:

But, I find this code SD card driver still have problems,so I can't send you directly now, I am trying to find the problem, this code project is based on IAR and MDK.

I still need time to make it work.

After it works OK on my side, I will send you ASAP.

Thanks a lot for your understanding.

Have a great day,
Kerry

Hi Kerry,

Thank you for the response. It would be greatly appreciated if I can get a solution to this.

Hi Ronan,

Please check this code for LPC54114, it is the audio, but it contains the SD card, and the dfs_fs file system, you can refer to it.

GitHub - Magicoe/LPC54110_Audio

dfs_fs is based on FATFs file system, you can check it on your side, you can comment all other audio code.

Please check it on your side.

Have a great day,
Kerry

Hi Kerry,

Thank you for your response. I m currently away today so will be sure to check this out tomorrow and I ll let you know if it works.

Thanks,

Hi Kerry,

I was trying to run a basic test with the SD card. As I m not using the full version of Keil, I cant run the entire project because I m limited to 32kb. I was wondering could you tell me which files I can ignore. In addition, is there a test file that you were using to create/read and write a file? I m having problems running this code. If you tested this on a LPC5411 device could you send me the code you used to test it?

Thank you,

Ronan

Re: Porting FatFs to LPC5411 with SPI throws a FR_NO_FILESYSTEM error?

kerryzhou — Thu, 14 Jun 2018 08:17:47 GMT

Hi Ronan,

MDK 32Kb limit is really too small to use.

This is the project's code size:

About the relate file, SD card, please check drv_msd_spi.c, and the filesystem.

Now, I just find this MDK project which is related to the LPC54114 sd card and the fatfs, we don't have any other project which can work directly, otherwise, I will send to you directly.

Anyway, I will help you to keep on eye on it, If I find any project which can work directly, I will send to you.

Have a great day,
Kerry

Hi Ronan,

You said, your own project already can read and write the SD card correctly.

But in your attached code, diskio.c, disk_write and disk_read, why you comment MMCReadMultipleBolck instead of MMCReadSingleBlock? Otherwise, the code won't be work.MMCWriteMultipleBlock is the same.

Do you test :

MMCWriteMultipleBlock

MMCReadMultipleBolck

on your side directly without the fatfs file? Actually, if both the SD card, and the write and read API can work on your side, the fatfs porting should be very easy.

So, I think, the Sd card leave code still important to check the function.

Have a great day,
Kerry

Hi Kerry,

The reason I had that commented out was because when i was in debug mode for f_open(), count = 1 so MMCReadMultipleBlock wasnt being used. In addition, it seemed like there was a mistake on the blog (Porting FatFs file system to KL26 SPI SD card code ). The MMCWriteMultipleBlock() was missing from the blog.

I m not sure if the way i implemented MMCWriteMultipleBlock() is correct. I was using code from a website, but i m not sure if it is right.

LPC1114 FAT下读写SD卡（原创） - 我心永恒的日志 - 网易博客

I have not tested out the MMCReadMultipleBlock() and MMCWriteMultipleBlock() but they dont seem needed for testing the f_open function.

Just now I tried to put back in the commented out lines and it still has an error.

I am also looking at the audio sample code you gave me but it is difficult to test.

Thank you,

Ronan
