Hi,I have a STM32MP157a-dk1 discovery board and a SX 1280 – Semtech (E28 2G4M27S - E-Byte) module. With CubeMX I add SPI5 to the architecture and get the outputs (Kernel, TF-A and U-boot files.) Then by using these output files I can generate the DTB...
I am using OSD32MP1 (based on STM32MP157c) in Production Mode with OpenSTLinux on Core A7 and FreeRTOS on M4. One of the tasks is to timestamp ADC data acquired by M4 at very highspeed, very precisely (think it order of nanosecond to microsecond). No...

Hello guys.I have configured ethernet on STM32MP157F using Microchip's LAN8720AI-CP.I base my image on st-image-core of Distribution Package. And dts is configured using CubeMX(meta-st-stm32mp-addons).Currently, it appears as if ethernet is connected...
Hi i am using stm32mp1 has codec which required i2s1 mclk enabled, before codec probe read the basic i2c read chip command need to validate further,note:The board does not have provision to get a crystal to feed MCLK of codec, so thats out of option...
i am trying to compile the third party OpenAMP folder in IAR with C++ and am facing a lot of errors.how can these be resolved.
We are new the MPUs and Linux. We received a new STM32MP157F-DK2 board, out of the box and boots up with the default binaries in the SD card.However, we find that the ethernet is not working (the LD3 is blinking). root@stm32mp1:~# ifconfig -aeth0 L...
Due to office environment and being behind the Proxy I am not able to build and flash (ports locked) STM32MP1 board from my PC at office.I have done the downloading and building of the Developer package at my Home PC (without any firewalls) and wante...
Hello,I need use STM32MP157 connect a USB printer. I followed this article(https://community.st.com/s/question/0D53W00000cSjHuSAK/stm32mp157dk2-printer-support?t=1630032775565), and the result is right. but when I use print command like (lp printer_...
