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 ...
Hello, we are currently designing a STM32MP257 based custom PCB. During the PCB design of LPDDR4 interface, we realized that the excel table provided by ST includes the package pin to PCB lengths and the calculations are done based on the track lengt...
Hii Team,I'm working on an ISP tuning project for an IMX219 sensor on an STM32MP257F-DK board, using the X-LINUX-ISP package and the ISP IQTune tool.I am facing some errors like1. The COM port is not getting detected in the ISP IQTune tool and giving...
