Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
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...
IHello, I am using the STM32MP257 platform and the user mode system programming adopts CAN0 loopback mode for self collection. I found that there is a probability of reporting the following exception in dmesg:ifconfig:
I’m working on an STM32MP135 (STM32MP13‑DISCO) using Yocto/OpenSTLinux 5.15 and trying to get SPI5 working via the spidev interface. My device tree configures SPI5 pins and enables spidev@0 at 500 kHz (see DTS fragment below). /dev/spidev0.0 appears ...
Is it mandatory to use a MIPI display in order to boot the system successfully? Is it not possible to boot using only an HDMI display?
Hello, I'm in the process of designing an edge computer using a MP2 processor. Due to the shortage of LPDDR4 memories, I'd like to use LPDDR4X memories. Can I use this type of DRAM for MP2 series processors? Or do you have any alternative part that I...
Hi,the TRM of the STM32MP257F describes different possibilities to boot the controller including the possibility to boot from eMMC or SD-card. And when looking to the EV-board, there are DIP-switches to choose eMMC or SD-card as boot-device too.But ...
