Bootloader to read from external EEPROM and write to MCU's flash memory
Hi community, I´m using an STM32F411RE with which I plan to create a custom bootloader with specific functions located on sector 7 of flash memory. These functions will read the data stored in an external EEPROM that contains a .hex file, which shou...
Help QuadSPI interfacing with MX25R6435F on B-L475E-IOT01A
I am developing an audio recording application that captures audio from a MEMS microphone, stores the data in DMA, and saves it as a .wav file using the QuadSPI protocol. I have integrated the FatFS middleware for file system management. While the co...
Resolved! Problem Loging data to an sd Card STM32U545CET6
Hi,I am a junior developer, and I am trying to get an SD card working on an STM32 U5 series MCU with SPI. I encountered a problem: in the middleware section of CubeMX, I don't see FatFS; instead, I only have FileX. However, FileX does not have an SD ...

Advice on STM32 MCU and Baremetal/FreeRTOS selection
Dear Forum,I am preparing a hardware prototype for a visual inertial odometry project that highly requires realtime-ness.The planned system would comprise an MCU for gathering data (with some pre-processing such as FFT, Kalman Filter, ...) from vario...
Resolved! Problem with NOR Flash W25Q512 cannot erase sector / chip
Hello,I have been trying to make a driver for the Winbond W25Q512JV, It's works normally ( I can read/write data, erase sector/chip, can write image as external flash loader with Touchgfx) until one day I could no longer erase sectors or full chips (...
Hard Fault in USBH_MSC_RdWrProcess() and USBH_MSC_GetLUNInfo()
I have a STM32H7 and I use USB MSC. I do not use an RTOS.If I plug in my USB thumb drive I append a counter to a file and close it.This works.If I remove the thumb drive very quickly at precisely the wrong moment I get a hardfault.if Appli_state == A...
