My ongoing difficulties running FATFS on an SD card has uncovered a problem! A read of the boot sector does not read all the data correctly, specifically the first 16 bytes are all zero. This means that FATFS reports there is no filesystem. The code ...
Posted on February 09, 2012 at 01:06Hi Chaps,Going slowly mad trying to get Chan Fat working with the sdio libs on a stm32f4.I'm using the most recent (1.0.0) library for the F4, and the low level access demo within that library builds and (at least...
HelloMCU has SD card & USB in MSC Device mode. I am storing data on SD card in csv fatfs format. The data from SD card can be read on computer by making connecting with USB. Now I want to encrypt the data so only my GUI application software on comput...
Hi, I am Murali Selvam from India, I have a doubt, Can we interface the external Micro-SD card through below given MCU, You have any reference schematic kindly give me. Thank you. STM32G0B1KBU6,STM32G0B1KET6
I have a custom board using the STM32L562Q BGA package processor. I have a high speed capable eMMC part with an 8-bit data interface. The STM Cube generated code seems to be correctly beginning the init and ID process, however after the 3 different ...
Hello everyone,I have been using for a long time the stm32L496ZGT6 in a customized PCB with an uSD card module. Never had any problem interfacing the card. Due to the shortage of supply during the pandemic situation I bought a couple of stm32L552ZET6...
Hello All, I will attach my PCB Layout as well as IOC file screenshot for reference. I am using this tutorial https://01001000.xyz/2020-08-09-Tutorial-STM32CubeIDE-SD-card/.I got it working on a nucleo board, but am transitioning over to the PCB now....
Background:I am capturing an image on OV5640 Camera module. My camera is connected with STM32L4R9I over DCMI protocol. I am further using DMA1 to take image data and store it in PSRAM (with the help of FMC). From PSRAM, image data is being written on...
I'm encountering an issue while attempting to configure my STM3240G-EVAL board to function as a “Mass Storage Device” with a microSD as Storage.I used the MX configurator and followed tutorials but encountered the same issue every time. I can compile...
Hi Everyone,I use SDMMC on my STM32H7 to write data on SD Card. I have several question :- for now I can't reach better rates than 12Mo/s writing, using 32Ko buffers and with the stm32 doing only that. Is that normal? I think I should reach the 25Mo/...
