Hey,I have an STM32H757 that I’m trying to program for the first time.When I try to program it using STM32CubeIDE or CubeProgrammer, I lose the ST-Link connection after programming one of the cores.Changing the programming order doesn’t solve the iss...
Hello, STM32CubeIDE Version: 1.19.0STM32CubeU3 Firmware Package V1.2.0 / 04-June-2025 When new project STM32 project with "enable Trust Zone" is created, template produced by STM32CubeIDE fail with HardFault. I have trace primary problem down to NonS...

Hi i am working with LTDC with STM32F429ZI Discovery -1 board with onboard LCD. I really want to drive a external LCD RGB display without An ic controller by utilising the Internal LTDC hardware inside the MCU . Can you please give some support on th...
Hi everyone.I'm trying to send more than 256 bytes of data from the host to the STM32 using USB CDC VCP, and I don't know why VCP won't accept more than 64 bytes of data. My project is already halfway done. If I switch to the USB bulk method, do I ha...
Hi, I have a question about supplying power to DSI interface on STM32H747BGT6 (208 LGFP package).RM0399 says, "The DSI interface is supplied from a dedicated VDD12DSI supply that can be provided eitherby the integrated DSI regulator or by an external...
I just spent some time debugging a fundamental compatibility issue between an MPU and its RAM, and I wanted to share what I learned to save others the same headache. I was looking at using the STM32N657 (a powerful Cortex-A7 MPU) and almost made a cr...
Hi, Im planning on using STM32H747BGT6 in LDO mode only and no USB interfaces will be used. What should I do with SMPS pins (VSSSMPS, VLXSMPS, VDDSMPS, VFBSMPS) and USB supply pins (VDD50_USB and VDD33_USB)? The datasheet nor the application note don...
Hi All,I'm new to using the STM32 and honestly had great grief trying to connect to the chip.I'm using STlink V3 and designed my own PCB.Trying to flash a F/W to the PCB. I ordered the PCB from JLCPCB.I keep getting unable to get core ID as a message...
The datasheet for STM32U585 and 575 list there are two SAI on the chip. In CubeMX I can only see SAI1 (A and B sub-blocks)Datasheet CubeMX pin menu
