Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
So coincidental enough all the projects I have done before required a RTC /w LSE. I am now working on a project that does not need a LSE, and I am finding that TF-A keeps throwing a panic because of this. The protos we had fortunately had the circuit...
Hi,We're working on a new open source wildlife camera system and planning to use ST's 1.5 Mp and new 5 Mp image sensors with an STM32N6x7 series MCU for routine MIPI CSI-2 camera interface, ISP, h.264 video encoding, storage and possibly CNN (Convolu...
Hello,We are using an STM32MP151 on a custom board and facing an issue with USB device connection via EHCI (USB 2.0).Problem description:After issuing a PORT_RESET, the J/K chirp sequence does not start, and we get a timeout error.If we disable EHCI ...
We ordered an STM32MP257F-DK evaluation board - DigiKey part number "497-STM32MP257F-DK-ND" - on 25 September 2025 and had it delivered to Zürich.On 15 October 2025 we ordered the same ST STM32MP257F-DK evaluation board with DigiKey part number "497-...
Hi everyone,I’m trying to connect a MIPI CSI camera to my STM32MP257F-DK board. I’m using Yocto (branch scarthgap) with core-image-minimal and created a custom Yocto layer to patch the device tree located at arch/arm64/boot/dts/st/stm32mp257f-dk.dts....
Spoiler Hi,I created a TouchGFX project for the STM32MP135F-DK board. When compiling the project, the error listed below appeared. Despite the error, I was able to load and debug the application on the board using the same procedure applied to any e...
Hello guys!I am trying to configure U-Boot on a stm32mp257f-dk board so that I can use the “ums” command with SuperSpeed. After configuring the device tree, I managed to configure the usb3dr as usb3(as it says in the debug printf written on the termi...
hi team,I'm facing issue connecting stm32mp25 gui tool with the STEVAL$USBI2CFTA bridge, the GUi tool says No bridge connected.I still haven't connected the other end of the USBI2C bridge to PMIC stpmic25a.I have installed the required FTDI 260Q driv...
hi, I'm trying to debug stm32mp157f-dk2 by using stm32cubeide by using open OCD and gdbAfter connection, I'm constantly getting below error.I can't even single step in or run. "failed to insert all hardware breakpoints; you may have requested too ma...
I would like to use MDMA on Cortex M4 to move data from DDR to SRAM in order to overcome the SRAM size limitation, especially in Ecosystem 6 secure context when a SYSRAM bank is dedicated to OPTEE.My idea is to move to DDR some data structures used b...
