STM32L071KZ MCU Flash Issue over ST bootloader

We are currently working on flashing an STM32L071KZ MCU using the STM32 bootloader.The flashing process completes successfully when using a 64-byte payload. However, when we reduce the payload size to 8, 16, or 32 bytes, we observe unexpected behavio

LittleFS support — official support status and OCTOSPI integration references

Hi,I'm working on a data-logging application using the STM32U575VGT6Q. I'm evaluating filesystem options for this.I have a few questions for the community/ST team:Is LittleFS officially supported on the STM32U575 series (or any STM32U5 platform)? Is

STM32CubeMX (MCUs)

Looking at the Ethernet PHY circuit of the STM32H735G-DK, the MCU and MAC are connected via the RMII interface, and a pin named "RMII_RX_ER" is connected to the MCU.However, if you configure it for RMII in CubeMX (version 6.18.1), this pin does not a
