Hello ST Team,I am evaluating the STM32MP215F-DK with the recommended M.2 Wi-Fi/BT module (Embedded Artists EAR00409 / Murata 2EL). I have encountered two critical issues that prevent the Wi-Fi features from working out-of-the-box with the standard S...
Hi,We are trying to make use of the ethernet interface in this fashion:- The board is a custom one with a soldered module from Karo, the qsmp-2550, that includes an stm32mp255fa.- The eth2 is connected to a PHY (TI DP83869HM) in RGMII.- The PHY is th...
Hello ST community,I’m an embedded software beginner working with the STM32MP257-DK board and OpenSTLinux (Yocto). I need help getting USART6 working on the external GPIO connector (PF13 = TX, PF14 = RX — CN5 pins). I have rebuilt device trees and co...
I have built a custom board by using STM32MP257F and I want to boot on USART6. I have not succeed to boot on USART6 when I compile my own fsbla by change the device tree of TF-A.I got a suggestion from ST Dev team to run this ROM tracedump wiki-stm32...
Hello, I am working with an STM32MP135f-dk device running Linux and trying to evaluate the possibility of using the USART peripheral in synchronous mode (TX/RX + CK). From a hardware point of view, the STM32 USART clearly supports synchronous operati...
Dear All,I have a total of 8 boards with eMMC from Alliance Memory. All of them boot from SDCard and work well. On 4 of them eMMC is detected correctly and boots fine with 50Mhz/8bit/ddr speed.4 boards are failing in exactly the same manner, that is:...
Please check STM32MP157F-DK2 no function issue after STM32MP157F-DK2.#1. After receiving the STM32MP157F-DK2 board, I connected a 5V/3A Type-C Power Adapter to CN6 and verified Linux boot and operation. LCD operation.#2. Updated the Linux image on th...
Hello I am planning to use STM32mp257Fak3 with DDR3L (16bit and 32 bit saperately),can you suggest some DDR part no and it's sonnection.
Hello,I am working with an STM32MP151 and I would like to start the Cortex-M4 core as early as possible during the boot sequence.The main requirement is to run a real-time task on the M4 that reads an analog input (ANA0 – ADC channel) with minimal st...
Hello,Currently I'm working on a project that requires a synchronized clock signal between multiple devices connected through Ethernet.The logic solution for this is PTP, and using linuxptp I was able to archive synchronous PPS on PG8 pin between dev...
