How can I build the M33TD Yocto images from sources?stm32mp2-m33td-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11 I managed to build the A35 flavor following this excellent summary:Solved: stm32mp257f-EV1 yocto - STMicroelectronics Community But now I...
We are using customised board on stm32mp257f microprocessor. We have used STM32MP257F-DK as a reference for the hardware design. In our customized board, we have used LVDS panel and kept the LVDS section same as that of STM32mp257f-dk board. The boa...
Hi,I am in the middle of the project development based on STM32MP257FAK CPU. Originally we were using 8Gbit Micron chip (MT53E256M32D1) which became obsolete in the middle of the development, it even seems that most of the 8Gbit Micron chips are now ...
Hi I was trying to connect a custom LVDS display to my STM32MP257F-dk board but it does not seem to work, The display has a resolution of 1024x600 pixel and also it uses "vesa-24" scheme, so i assume that i don't need to change the device tree as it ...
Hello,We are working with the STM32MP257F-FK Discovery board and are facing an issue while calculating the signature of a memory region.We are following the recommended sequence for initiating the signature computation. The CRCEOC flag is being set a...
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...
My freshly arrived and assembled STEVAL-ROBKIT works well in Autonomous and Follow-Me mode but not in Drive. Nor does the "lock" toggle seem to do anything. Lock does not stop Follow-Me if activated. Any ideas?John FergusonSt Petersburg, FL
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-...
