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,I need help to setup the DeviceTree for our custom board using STM32MP135FAE7 and TI TLV320AIC3254.I have read the Wiki about SAI and read and tried to implement SAI using these posts as reference:https://community.st.com/t5/stm32-mpus-products/st...
Hello,I am working with a SOM based on the STM32MP157C and I am trying to bring up a display panel that uses the Sitronix ST7703 MIPI DSI controller.The operating system has been built with Yocto using the BSP provided by the SOM vendor. This BSP is ...
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 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...
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 ...
HiI am using STM32MPU25 to evaluate object detection, when i use stai_mpu_object_detection binary to run default ssd_mobilenet_v2 models , i can see object detection works.when i run python scripts to launch application( example : launch_bin_object_d...
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...
