I'm planning to use the built-in ROM bootloader in an STM32F4 chip for DFU uploads and having a hard time figuring out how it works exactly (in particular what pins it initializes at what moment in the boot process, and what I need to do externally t...
I have an issue with STM32L462 when using the ROM bootloader via UART to enable readout protection. It just hangs after enabling RDP level 1 and requires power cycling to recover. With several other STM32 MCUs (F0, F3, H7, ...) this seems to work.The...
To save the least uA in one design I leave the VDDUSB unconnected until a powered USB is plugged in. When the 5V from USB is present a transistor enables the 3.3V to reach the VDDUSB pin.The code generated by CubeMX strightly calls MX_USB_DEVICE_Init...

I am using STM32H750 with eMMC in MSD mode, with code generated by CubeMX Version: 6.1.0. USB works in HS mode with external phy USB3320.USB MSD correctly recognized by PC, but when i try to download file from it, transfer crashes in random time. If ...
The Problem is when I activate SDIO,Virtual Com Port does not work anymore. The device is not fount from PC. Any Ideas?
hi, recently, I am try to use cubeide to directly generate a basic project for future development. In this basic project, I am trying to integrate lwip stack I am now confused by one weird behavior, when I configure the memory for lwip internal heap...
is it possible to verify the FW version of MCU using stlink or some other stm tool ?i have programmed my MCU with FW version 5.5.5 and i would like to verify using JTAG or stlink or some other stm tool.someone told me it is factory protected you cann...
Build environments are pretty touchy with project tools that generate middleware code and changing tool versions. Given this environment , (1) what files should be under version control? (2) If the project has 30 user modified source files and 150 to...
I would like to implement a bootloader for STM32F103C8T6 that would count and keep in a special protected area how many uploads has done over its flash memory. Does anybody would give some some reference about this matter ? Thanks a lot. Antonio
