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 can write a program generating interrupts ?  

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 far as I know, an MCU would be pretty tight to run all of this, so we are thinking about using an MPU. Can someone help me ask the right questions to choose the correct MPU?  I have worked with STM32MP15 in the past, but this was for a GUI related product, so I don't have full experience to choose a non-GUI MPU.  Thanks a lot in advance

Hello everyone,We are currently working on a project based on the STM32MP2 platform and are evaluating solutions for reliable OTA updates. We're particularly interested in using Mender for this purpose.However, so far I haven’t found any official documentation or community references about Mender support on STM32MP2. I’m aware that Mender has been successfully integrated on STM32MP1 in the past (e.g. Yocto-based builds), but it’s unclear whether the same applies to the newer MP2 platform.Questions:Has anyone successfully integrated Mender on STM32MP2?Are there any known limitations or blockers specific to this platform?Any recommendations on bootloader setup, partitioning, or Yocto layers that are MP2-compatible with Mender?Thanks in advance

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 that, read it's counter on both A7 and M4 and share the values to calculate difference.And here is my question, how can I enable STGEN in my own linux image (I am not using OpenSt distribution right now). My image is basing on core image minimal.When I try to read STGENR registers provided in RM0436 with that piece of code (it is executed by M4):#include "stgen_read.h" #include "openamp.h" #define STGENR_BASE_ADDR 0x5A005000UL #define STGENR_CNTCVL_OFFSET 0x000 #define STGENR_CNTCVU_OFFSET 0x004 #define STGENR_CNTCVL_REG (*(volatile uint32_t *) (STGENR_BASE_ADDR + STGENR_CNTCVL_OFFSET)) #define STGENR_CNTCVU_REG (*(volatile uint32_t *) (STGENR_BASE_ADDR + STGENR_CNTCVU_OFFSET)) #Debug purpose extern struct rpmsg_endpoint ept; uint64_t

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 header to the SD holder using jumper wires.When I insert the Wi-Fi module into this setup, it fails to get detected and throws one of the below mentioned errors, such as:mmc1: error -16 whilst initialising SDIO card mmc1: Card stuck being busy! __mmc_poll_for_busy mmci-pl18x 48004000.mmc: card claims to support voltages below defined range mmc1: error -84 whilst initialising MMC cardHowever, when a standard SD card is inserted into the same slot, it is detected correctly and works as expected.Could you please advise if any changes are required in the Device Tree (DTB) or if any hardware modifications are needed to enable proper detection and operation of the Wi-Fi module?SDMMC3 node configuration in DTB file as below :mmc@48004000 {compatib

I have created a CubeMX project for STM32MP235.I have successfully built, Flashed and able to boot it on STM32MP257-EV1 board. (I don't have my 235 custom board ready yet.)Once I switch to normal boot after flashing, it runs until kernel tries to run some process printing message on Serial "[ OK ] Started Calibrates HSI/CSI clocks." after which IAC exception handler kicks in from OPTee and system crashes.From the log what I can see that kernel is asking for access to peripheral ID 156, which I presume that is RCC. (found ID from reference manual and some online posts).Can anyone help me which setting I am missing in my cube MX project or any User entry in any of DTS that cubeMX generates?Here is the snippet of Console Log.

I'm currently evaluating an embedded linux system for a specific use-case with my company.What's necessary is a lot of specific interfaces, like MIPI-DSI/DisplayPort/HDMI, USB HS (+PHY) and the standard RAM and other peripherals. I've found the STM32MP257FAK3, or more specifically the Discovery Board STM32MP257F-DK from ST to be sufficient for my task and would like to keep working either with it directly or with something very similar - that's where the issue starts.In ST's license agreement, the commercial use of a DISCO board is prohibited, so buying them directly from ST and using them as components in their designated machines is not an option.Out of curiosity, I've used the publicly available BOM and manufacturing files for the DISCO board for a lower-volume quotation, just to see where a custom and perhaps reduced board would get me - let's just say a very popular pcb manufacturer would like 3.5k for 5, yes, 5 boards. The components make up for most of the cost, but buried

Hello everyone ! I use the stm32mp257f-dk with yocto for a project. To benchmark my programs, I need kinda heavy packages. To solve my IMAGE_ROOTFS_MAX issue, I followed the following topic : https://community.st.com/t5/stm32-mpus-embedded-software-and/increasing-the-rootfs-size-on-a-stm32mp157f-dk2/m-p/205665Unfortunatly, even if the distro compile, I have the following warning at the end of my compilation (see screenshot below).My configuration is the following :- local.confROOTFS_PARTITION_SIZE = "12582912"IMAGE_ROOTFS_MAXSIZE = "12582912"I tried to add the in /meta-st/meta-st-stm32mp/conf/machine/include/st-machine-common-stm32mp.inc too, but i don't have more results.I don't have any more idea to solve the issue. All the help is welcome !

Dear sir/mamWe are currently working with a custom board based on the STM32MP257D processor and are attempting to boot Trusted Firmware-A (TFA) and U-Boot. For this purpose, we have used the defconfig of the STM32MP257F-EV1 development kit as a reference.Our hardware configuration differs from the EV1 kit in the following key aspects:The PMIC on our custom board is connected to I2C4, whereas the EV1 kit uses I2C7.Our board utilises LPDDR4 memory, while the EV1 kit is equipped with DDR4.We have made the necessary adjustments in the device tree and platform files to reflect these changes. Despite this, we are encountering a panic during the boot process from the SD card.To isolate the issue, we attempted to comment out the PMIC initialisation code located in the bl2_platSetup.c file. With this change, the boot process fails with the message ddr_power_init failedFurthermore, when we bypass the stm32mp_board_ddr_power_init function, the boot log shows the following errors:ERROR: ddrph

Hi everyone, for learning purposes I’m trying to build meta-doom for stm32mp257 DK. I previously tried it for RPi4 and after some minor fixes I was able to do it for nanbield/mickledore poky version. What I established it is possible to run it and it still works.My setup for stm32mp2 version is that I cloned mickledore repo manifest and integrated meta-doom layer. Doom wouldn’t buil for wayland so I had to change my display manager to X11. It’s not directly supported but still possible (source: https://community.st.com/t5/stm32-mpus-embedded-software-and/how-to-setup-x11-in-the-distro-instead-of-wayland-on-stm32mp1/td-p/741125)Now gzdoom builds and I’m able to execute on target. However, after uploading proper WAD I get this error:no vulkan device found supports minimum requirements of this applicationI installed vulkan-loader and vulkan-tools into the image and vulkaninfo gives me following information:root@stm32mp25-disco:~# vulkaninfo WARNING: [Loader Message] Code 0 : loader_scanne

Dear sir/Mam While analyzing the reset handler code within the bl2.elf binary from Arm Trusted Firmware, we observed that the label S3_15_C2_C1_1 is being referenced in the cortex_a35_reset_func. We would like to request your clarification on the following points:Could you please confirm whether S3_15_C2_C1_1 refers to a system register?If so, is S3_15_C2_C1_1  the official name of the register?Additionally, we would appreciate your guidance on where this register is documented and how it can be accessed (e.g., using MSR/MRS instructions or through a specific architectural feature of the Cortex-A35). Thanks & RegardsAkshitha Pattem
