Hello,I am using a Riverdi RVT101HVSNWC00 board (with STM32H757) for a product that needs a display, interfaces to devices, and writes data to a microSD card. After communicating with Riverdi, I gathered the correct SDMMC1 configuration to make the p...
Hi,I'm using an STM32H7A3ZI MCU, with freeRTOS, fatFS & DMAI have set the SDMMC2 peripheral with 4 bit mode & DMA (by default in STM32H7 MX config). I have implemented the code from this example to test my SD card (microSDHC 32Gb, also test on 2Gb SD...
Hi all, i am planning on making an adapter board to use SD cards as a storage media for ipod classics which uses IDE hard drive. I will be using stm32f407 (512kb) for the development works. And yes i looked around and there seems to be no ic currentl...
Hello,Because there are negative side effects of using FatFS in my program to write logs to an SD Card, I am trying LittleFS library with an implementation of the HAL library.When I mount the filesystem &lfs I get a result of -84 which indicates that...
The hardware is configured, initialization passes (fails if no card is inserted).The card is 8GB micro SD formatted on Windows with exFAT, contains 1 file "test.txt" with content "HELLO".The exFAT option is enabled for the FATFS.Here's my code:FATFS ...
Hi, i'm using STM32U575ZI-Q (in NUCLEO-U575), I want to write and read Fat32 files on SD using SDMMC interface, with FileX middleware. When I set the bus width in 1-bit the app work OK but when I switch the setting to 4-bit buswidth mode the app cras...
hi I want to implement mass storage class in STM32H743BG controller. but there is no SDIO pin, we arrangement for SD card and external flash.it is possible to implement it on external flash(IS25lQ128).thanking you
Been trying to get an test application working on a STM32F469NIH Discovery board.Should be fairly simple - Write a file to the SD Card, with FatFS, the read back:Try as I might, I couldn't get things working.After a bit of debugging, I think the issu...
Posted on May 26, 2017 at 06:18 Hello, I am using STM32F411RET6 chip to access uSD card with SDIO 4bit. By default it uses polling mode to read/write data with SDIO, such asBSP_SD_ReadBlocks(). The problem is that I want to continuously wri...
Hello,I'm using NucleoU575 with CubeMx and I want to make a file system on my SD card.I want to use FreeRtos but there are no Fatfs in CubeMx and the FileX cannot work with FreeRtos (image). Is there anyway i can use Fatfs with STM32U5 ?Thank you.
