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 referring to the STM32MP157D-DK1 EVB (STM32MP157DAC1), specifically the "mb1272-bdp" design file, and would like to clarify the correct method for measuring DDR3L to Microprocessor (MP) trace lengths on the PCB.My question is regarding the Cl...
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?
Hello ST team,I came across issue here.The force_mode of boot_ctx is always set to 3, which force the MPU to boot over USB, rather than MMC. I tried to set TAMP_BKP20R(BOOT MODE) to 0, but the behavior is the same after reset.Aslo, I have another boa...
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,i want to store some flags, bytes, at the end of my SRAM. This RAM section should preserve the information in case of a Reset e.g. WWDG1 Reset.Before WWDG1 Reset is executed some program states should be stored in RAM and after Reset could be read...
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...
