I have had difficulties programming the STM32MP257 via stm32cubeide. I followed the first few steps to flash an OS image onto the board using the section populate and boot the image, from the STM website. When trying to flash IOC generated code via s...
Dear All,I'm having problem to get DFU over USB running on custom board.In general device can boot from SD card and with no SD card it can be detected via uart4 by STM programmer, so it enters DFU as far as I can tell.USB DP/DM is connected to DP2 (b...
Hello Experts,Based on STM32MP257F-EV1 we have designed a custom board. For the DDR, PMIC, and eMMC we tried to follow the EV1 rooting as much as possible. There are few differences on the BOM though: Our DDR chips are Alliance Memory AS4C1G16D4A-62B...
Hello,I am testing a custom board based on STM32MP257FAK3 with two DDR4 MT40A1G16RC-062E_B devices, for a total of 4 GB (32-bit width).I have correctly set up the main configuration files to work with the PMIC and UART. I also exported the PCB layou...
Hi, I tried exporting the IBIS model from ST website. On importing model to SI tool I can see that there is no model assigned to DSI lines. It is showing NC. Can you share the IBIS model with MIPI drivers in it. or share some IBIS model which I can u...
Hello, I am working with the STM32MP135F-DK development board and trying to interface the onboard GC2145 camera with the STMIPID02 MIPI-to-parallel bridge. The goal is to convert the camera's MIPI output to parallel data, which is then received by th...
Hi,We’re working with an STM32MP157DAC SoM for driver development and testing. Right now, every time we make a change, we have to rebuild the full image, which takes around 1 to 1.5 hours. I’d like to speed this up by building only the kernel separat...
Hi ST,I'm working with the STM32MP257FAI3 Processor and have some concerns regarding DQ bit swapping between the SoC's DQ lines and the DDR4 RAM DQ lines.I'm already aware of the guidelines document mentioned in this solution.From my understanding of...
Hello,I have a stm32mp257f-dk and I would like to create an STM32Cube project for my board.To be able to use the board, I have put in the eMMC the tsv file provided in the starter pack:`en.FLASH-stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.12.05/...
Hi I am using Marvell Ethernet Phy(mv88q2220) in our project,i have integrated my Marvell driver into SDK and it is probing as well, we are using sxgmac driver for mac, while i am trying to initialize the eth0 interface i am facing issues related to ...
