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....
Hi,we use the STM32MP157C with almost the same RAM layout as the STM32MP157F-EV1, except that the SDRAM chips are from Micron (MT41K256M16). The PMIC is also the same as the one on the evaluation board, and the settings therefore are identical. TF-A,...
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...
I have developed a c application, I have some html pages that are ran through nginx . For now they are exposed , any one gets the board access can see these files and copy the files. My question is How can I secure my files.
Hello ST community,I’m an embedded software beginner working with the STM32MP257-DK board and OpenSTLinux (Yocto). I need help getting USART6 working on the external GPIO connector (PF13 = TX, PF14 = RX — CN5 pins). I have rebuilt device trees and co...
