Hello,We are currently working with the STM32MP257F-DK development board and encountered an unexpected behavior while accessing the Ethernet DMA Mode Register (ETH_DMAMR), located at address offset 0x1000 as per section 92.11.2 of the reference manua...
I'm using a custom board, and use the optee device tree generated by STM32CUBEMX and full UART log. Panic at core/kernel/dt_driver.c:904 <probe_dt_drivers>. How to solve this problem?
Hi, I have problem config LTDC for 1280x720 @60Hz. Without caching it works no problem, but slow.We are using 32MB SDRAM 16bit, config at 100MHz. When we use MPU to cache SDRAM, code as below:```MPU_Region_InitTypeDef MPU_InitStruct;/* Disable the MP...
What is FOO driver in https://wiki.st.com/stm32mpu/wiki/Interrupt_overview Interrupts overview should we have mention in our device tree files please explain me for better understanding I am a beginner. My goal is to fix few GPIOs as interrupts. How ...
Hi ST team!I need to create a gateway that will connect a web server to a variaty of nodes. The gateway will connect a few universes of DMX/RDM and DALI protocols. I also plan to add a LoraWAN and OTA feature. We are not planning on using a GUI. As f...
Hi, I am working with STM32MP157A-DK1 board with Yocto build system.I am trying to build synchronised system, that means I want to synchronise both CortexA7 and CortexM4. Basically I want to have the same time at both of them. I want to use STGEN for...
Hi everyone,I'm currently working on the PCIe part of the STM32MP25 and would like to ask if there's anything wrong with my configuration. I’ve followed the official documentation provided by ST.Here are the documents I’ve referenced:PCIe device tree...
Hi all,I'm working on a custom STM32MP135 SOC hosting a MMC memory. The original firmware creates some tasks by the osThreadNew() function and works correctly.Now I'm inserting FileX module on the firmware to support a FAT fs on the MMC memory.The fi...
I am trying to control the LTDC on the STM32MP257FAL based on the STM32MP257F-DK board, but I am unable to configure pin PH4. This pin is used as LED1 on the STM32MP257F-DK board, which is the LED near the button. However, I cannot find where this pi...
I am using the STM32MP157F-DK board and attempting to connect an NXP Wi-Fi + Bluetooth module via SDIO through the 40-pin expansion header. For this, I designed a custom PCB with an SD card holder and connected the SDIO lines from the expansion heade...
