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 ...
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 ...
Hello, I want start on a project using the STM32MP157 processor.Working on an embedded Linux OS is a first time for me. I understand that there is a steep learning curve to get the OS running an embedded system. Is there any advice for a new come...
Hello,I am designing a custom board with stm32mp257,As given in evm it is connected with 4GB eMMC on SDMMC2, But I require 32GB 0r 64GB, can you suggest some eMMC for it.Best RegardsAbhineet Ranjan
Hi, everyone. FYI:I have a board STM32MP257F-DK-C01. I flashed the latest release according to https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-DK/Let%27s_start/Populate_the_target_and_boot_the_imageIt starts and everythi...
Hello,I'm following the Getting started wiki for Developing on Arm® Cortex®-M33. I already installed the IDE and the MP2 Packages. Now I'm in the section "Modify, rebuild and reload the firmware" but I'm stuck in Step 2. Software Prerequisites. Becau...
