Thank you so much for posting this video! I was able to get it working with an SD card formatted with a block size (allocation unit size) of 512 bytes. How do you get it to work with other block sizes (for example, I'm trying to use a block size of 4096 bytes)? Is that possible?
@@ControllersTech Thank you. I can get it to work with cards up to 8 GB, but over that, they don't work. Is there something special I need to do with >8GB cards (other than format them with FAT32 and 4kB block sizes)?
Thanks for the video. I tried to do everything according to your video, but it doesn't work. I'm working with the same SD-card module as you, but with an STM32L432KC. The first problem is that I don't have fsize parameter in FIL typedef. And the second is that it always says that the card is mounted successfully, even if there is NO CARD in the reader. What is more, I get Disk_error if I try to write or read a file on the card. Could you please help me?
Try writing this DSTATUS my_status = SD_disk_initialize(0); if(my_status == STA_NOINIT ){ send_uart ("error in initializing SD CARD... "); } if (my_status == STA_NODISK){ send_uart ("No medium in the drive... "); } if (my_status == STA_PROTECT){ send_uart (" Write protected... "); } This will help to know if your disk initialization fails. Remember to #include "fatfs_sd.h"
@@ucNguyen-wu2xh I am using the STM32L4KC too. I used the same files that he used in the video, but I changed the HAL library with this #include "stm32l4xx_hal.h" in the fatfs file, and it worked.
Hello @ControllersTech I'm using the same MCU and same IDE as in your video, but my code gets stuck at HardFault_Handler(void) when i try to open a file. how to solve it?
In my project (STM32G017...) f_mount did not succeed but simply hang. Upon further debug inspection it hang/loop endlessly inside a HAL_DELAY() function (fatfs_sd.c --> void SELECT(void) --> HAL_Delay(1))... I followed the answer in this thread by overwriting the HAL_Delay function: community.st.com/s/question/0D50X00009XkXJp/hal-delay-stuck-in-infinite-loopnewbie I did not understand whats the cause of the problem but this answer worked for me. Maybe this helps someone else too.
Great video, thank you so much for your help! As other users have mentioned, if using an stm32f0 discovery board, make sure to set the spi data size to 8 bits. I also ran into a error where I could not build my project with a max sector size of 4096 (too large) so I changed it to 2048 and it worked fine.
Awesome tutorial. I can confirm that this works on clone chip CS32F103 Bluepill board using 32Gig Transcend SD card . Thank you Controllers Tech for your hard work.
Great Video! Some boards set SPI to 4 bits ( hspi1.Init.DataSize = SPI_DATASIZE_8=4BIT). I changed it to ( hspi1.Init.DataSize = SPI_DATASIZE_8=8BIT). Btw I am using STM32F0Discovery Kit
Hello! Thanks you for the video! My controller is F103C8. How can i get throw away trouble with an error of mounts the SD card while microcontroller initialized? I had my spi speed set to about 2.5MB. I'm was formatted my sd card to fat32 file system, block size 512. p.s. miso mosi connected cross to cross. p.p.s I'm use external +5 volt supply for sd card module. Maybe I'm doing something wrong?

hello , first of all thanks for this tutorial. I tried this project with stm32f446re and it works pretty well. But i need to save a value every 10us at specific .txt file. For this reason i open , write and close the .txt file into an tim_irq_handler. It seems that the proccess of saving the data takes longer than expected. Do you have recommended changes in the above code to enhance performance? Thank you !
Hello, Everything working well. But i need to log 10 bytes of the data after every 5 milli seconds and this should be done for 24 hours, The SPI hangs (remains in busy and locked state)after some times and i can only write for few mins of data. Please suggest
hello, I followed all the steps but every time I find the sd-card empty. I tried to find what is the reason for that by making leds light at every operation of the SD_card function and found that the function enters the first if condition which mean (No SD Card found) and break.
Your software for me not worked. I make all the things and the total size shows zero and not write or read anything. I did all of the video and not work. I am using 2GB micro sd

i m using this method and one of my sd card is working fine but other is not working. But both sd cards are working fine in laptop. I dont know what is wrong.
Good morning i have a little project that i have to do but do you think that we can transfer files between two stm32 with spi ( files like .txt) thank youu
Thank you very much for your initiative. The only sensible code that I found after a long time of searching. But in the beginning there was a problem: the program did not always work. In the end, the whole problem was in SPI1. After connecting the microsd module to SPI2, the program always worked. I'm using stm32f4discovery (stm32f407vg microcontroller).
@@НикитаЩербаков-ж3х I'm using the same item.I didnt get it worked. Could you tell me what was the error ? Are you also sure that it's all about SPI1 ? Thanks in advance..
@controllerstech am using stm32l476rg micro controller when interfacing with micro sdcard adapter am using your program to control it as per your procedure to settings in cubemx....but i get the "ERROR!!! IN mounting sd card" what mistake maybe occurred in my side...please give the solution
You are getting error in mount itself. There isn't much i can do here.. It Could be anything.. Check your connection Sd card is in FAT format ? Check the SPI speed, it should be around 2Mb/s Check the connection again.. there could be a loose wire.
Hello. I do it as in video it work! Thank you so much! But I not achieve success this project work with PC and mass storage class configure my project. You have video wich see how to work with mass storage devices? I tried on STM32F103C8T6 and STM32F401CCU6...
I already use ur code and works inside HAL_TIMPediodElapsedCallback, but max interrupt speed that I could generate is about 0.5 sec, I need it to be faster, what should I do?
Thanks for the video!! Worked here in my STM32L152 Disco board, with minor adjustments. I was able to create files, write and read. However, a few weird outcomes: total and free sizes result with a dot before the number (numbers seem correct); also, the current version of FIL struct in ff.h doesn't seem to have the .fsize field, so I haven't found a way to read the correct amount of bytes yet. Thanks again!
I am generating code for STM32F32373c using STM32cubeIDE ,but how can i add fatfs_sd.c and fatfs_sd.h I am unable to find this file. Please help me .....thank you
Every 512th character in the file is in error. This must be an indication of the block size being in error or something. What do I have to do, format the SD card? It says its block size is 512
It's the same for other STM, I use the stm32l432kc and it works fine. For doing so, you have to change the name to the library according with your microcontroller in the fatfs file. For example: #include "stm32l4xx_hal.h" I included this in my case in yours: #include "stm32f3xx_hal.h" I think
I commented this lines and it is working now, pay attention everybody that is anyone that is starting with this example to comment this if you want to put the sd card in your pc to see the data that was written on the sd card. I used a 16GB San Disk Ultra MICRO SD HC I and now worked. I think that cards with 2GB not work because i tested with 2 of then, maybe i should make the same thing that i did when formatted the sd card. The codes of control tech work really, but if you download the already code you have to follow the comments of the video about change MAX_SS to 4096 and USE_LFN to ENABLED WITH STATIC WORKING buffer on bss . When you format the SD CARD should make with FAT 32 and choose 4096 bytes. And slow the speed of SPI to 2.25MBps and i put external 5V power. Control tech have very good videos. I don´t like when my things not work, sorry about my declaration that i did before. Thank you very much for this video. And i am sending my contribution to this site. /*************************REMOVING FILES FROM THE DIRECTORY ****************************/ /* fresult = f_unlink("/file1.txt"); if (fresult == FR_OK) send_uart("file1.txt removed successfully...

@@ControllersTech What do you mean by not generating the code properly? I am using CubeMX version 5.5 to generate Keil projects. I added fatfs_sd.c and .h to their folder (Src and Inc respectively), and clicked "Add Existing File to group Application/User". Is there anything else to do to properly link the drivers?
@@ControllersTech Would it be preferable for me to use SDIO, rather than SPI, as it seems my board features a 4bit bus SDIO interface, which I've heard is 4 times as fast as SPI?
Ok I built this for STM32F411CEU WEACT board. using Chan's FatFs R0.12c Everthing works good except the "file.size" reference. This has been replaced in ChaN's FatFs R0.12c version with f_size(&fil).

I don't know. It could be anything... Are u initialising all the peripherals by your own or using cubemx ? Also check what error are you getting. You can do this by checking the error status.
Hello, I have a question. I'm using FreeRtos and Timer 1 as the source, so there is no SysTick_Handler fuction in stm32f1xx_it.c. Where would I put the FatFsCnt check in this situation?
Hello thx for this tuto ! I would like to do the same but with ide arduino ... I didn't find help in the internet, do you think it's possible to interface sd card with stm32f103c8 using spi and arduino ide ?
I did in Arduino and the SD CARD kit that i have work very well. I buy one like your video, but your software don´t write or read anything of SD CARD, not work. I tryed to format in PC but nothing happens, always the same bad things.
You posted the comment on the website right? Just because you can't get it to work, "you think the code is very wrong" ? Sort the comments to "newest first" and see how many people got it to work.
@@ControllersTech Yes, i did all the things and not write or read, but with arduino read and write. I format with fat and then i tryed with fat32, anyone works. Why in arduino works very well. I have blue pill stm32f103c8t6 and i have this board to put the card
@@ControllersTech I copy your program and nothing happens, i did a lot of times and nothing happen or 2G micro SD card, only with Arduino, this is my question. Maybe there is something very simple that i don´t know
I don't know why it isn't working for you. Try using external 5V supply to the module. Don't use the bluepill's 5V. Also some particular types of sd card don't work. I don't remember which one exactly, but read the comments as some people have pointed it out.
Thank you very much. I use stm32f103c8t6 and 2GB SD Card. but when run this code, I get successful mounting, 0 free and used space and nothing is created on my SD Card. could you help me please?
I had made some changes, there are some variables types that are not right. I run this project at 18MBits/s with no errors. I used keil uVision. // "sprintf" needs an "unsigned long" input. Note that despite the fact that int and long are represented by the same number of bits, they are still different types.
"0" means the card can be mounted later also. We have executed the command and now it can mount anytime. "1" means mount the card immediately. "/" Is the path of the sd card, where the mount will take place.
It seems f_write can not exceed 1023 for "btw" which is the number of bytes to write. If I try to write 1024 byte, I have FR_DISCK_ERR. Can you help me, if that is the maximum length I can write Or there is another problem to be solved. Thank you
the problem solved. I think it is a bug in the Fatfs_sd.c In function "SD_TxDataBlock" there is NO "return TRUE" if the token =0xFD, it will be always "return False" my solution is just adding "else" for the "If" statement and return TRUE there. Also, eclipse raise a warning there ('resp' may be used uninitialized in this function) which is make sense in case of 0xFD token.
Are u serious ? Temperature is a float value.. f_write accepts a buffer.. Use sprintf to convert and store those values in the buffer. And then send buffer
Thank for going to the effort of publishing this. I’ve been wanting to get this working for a while so this video is going to be really useful. So far I’ve only “skim” watched it, and I’ve also looked at your website, but in both cases and for the life of me I can’t see where your fatfs_sd.c and fatfs_sd.h files are coming from. i.e. you say copy them into the project, buy where are you copying them from ? Apologies if it’s obvious, and thanks again.
I open a text file, type something and close it, I want to open it again and add something else without losing what I wrote first. it is not working.why?
I am using F401RE. I am finding problem in disk initialization. 1. Even when I am not inserting the card there is no difference. It is executing f_mount successfully. 2. The program does not enter the line ENTER_FF(fs) in ff.c for volume locking.
1. Yes that's the bug in the code. 2. I don't know much about it. I ported the code so that it can work with HAL library. What kind of error are u getting exactly
@@ControllersTech I am not able to fetch any values in fs FATFS pointer in ff.c. I am unable to understand why this is happening. I also tried to understand and fetch information about the libraries. But none understood to an extent to solve the problem. Also how did you port the code ? Probably that can work for me too.
There are few things * Some users have reported that SanDisk cards are not working. * Make sure the sd card is formatted in FAT * Use the smaller size at first. I have used a 1GB card while making this video
@@ControllersTech I am using F401RE nucleo board. Is it possible that there might be a hardware problem? I read at some places that that might be an issue.

Can't say really.. which controller are u using btw ? Try not using my code. See the video and write yourself. That way you always know what u r doing and the places, where things get messed up.
