STM32 MPUs Products and hardware related

Dear ST Rep,  The information within AN5489 regarding the pin-lengths for the high-speed serial interfaces of the MP2 (ie,. DSI / CSI / LVDS / and "COMBOPHY") potentially has some errors, or at the very least is unclear and I would greatly appreciate some help making sense of it.  Side note -  The raw pin-length data provided for the DDR interface is exactly what a designer wants/needs in a design.  I'm not sure why the same information for the other high-speed interfaces on the MP2 was converted as it was, but it's far less useful (imho).   If the raw pin length data could be provided for the above-mentioned interfaces - all my questions will be answered.   To that end - I struggle to make sense of the information regarding the trace length matching for high-speed interfaces (via AN5489), for the reasons stated below: Per Section 8.19: (pg. 78; Rev3)"Each package has been optimized to provide easier length matching when diffe

I am following the contents of STM32MPU Distribution Package in STM32 Wiki6. Building the OpenSTLinux distribution↑.When I build using the bitbake st-image-weston command, the following error occurs.ERROR: openssl-native-3.2.2-r0 do_compile: oe_runmake failedDoes anyone know about the above problem? (I'm using Ubuntu 22.04.)

Whether the part STM32MP131FAE7 can be reflowed twice or any solder requirements

When will this product be available in retail ?  The ECO system already supports this board but there is no STMICRO hardware, except the EV board. 

 [1] Why is the STM32MP257 called STM32 and not STM64 :) for 64 bit ?[2] What is the reason the board uses as display output LVDS instead of the 4 lane MIPI and/or RGB888 ?    

Hello Anyone can Help me to solve this Issue  I am using STM32MP257F-EV There is  a week ego try to troubleshoot this issues by installing all necessary drivers  but still not working , when I want to run the code via IDE it is showing busy and COM ports number, Any assistance please

I enabled CAN in the device tree using STM32CubeMX and followed the instructions in the provided documentation to generate the .dtb file. Afterward, I copied the generated .dtb file to the /boot directory. In the terminal, I ran the following commands: sync reboot After rebooting, I checked the dmesg log and found the following output when filtering for CAN-related messages: dmesg | grep can [ 0.451665] can: controller area network core [ 0.451819] can: raw protocol [ 0.451832] can: broadcast manager protocol [ 0.451847] can: netlink gateway - max_hops=1 However, when I checked the available network interfaces can0 isn't avaliable root@stm32mp1-e1-99-00:~# ls /sys/class/net end0 lo usb0 wlan0 I have attached the dts file for reference

Hi,I am designing a product based on the STM32MP157DAC specifically using the TFBGA257 package due to its compact size. I was just looking at the datasheet (page 16, Table 1) and noticed that under the SDRAM section it seems that this package doesn't support 32 bit. I have trawled the internet for additional information to support this but can't find anything that might suggest this to be the case. Can anyone chime in if you've had any experience using this package or if you know of any additional literature. Cheers,

Hi,i have a question to the memory-controller and the supported memory-size.I'm using the Part STM32MP157CAAx (Package: LFBGA448).In the Datasheet (STM32MP157C/F) and AN5031 there is a definition to the supported SDRAM size.For package "LFBGA448" the SDRAM is defined as following.- DDR3/3L (16bits 533MHz) up to 1Gbyte., single rank.My Questions:a.) Does the Memory-Controller support a DDR3L (Configuration 512Meg x 16) with "Single-rank and Twin-Die?b.) Does the Memory-Controller support the following Page sizes:     - Page-Size= 2KB     - Page-Size= 1KB (Page size per die)Could you please give us support, to answer the questions.Thank you.Reguards        

Hello, I am working on bringing up the STM32MP257F-EV1 board and running into a problem with the steps on the page: https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-EV1/Develop_on_Arm%C2%AE_Cortex%C2%AE-A35/Modify,_rebuild_and_reload_the_Linux%C2%AE_kernelSpecifically step 4 when it has you build the Kernel and the device tree.  When I run the command make ${IMAGE_KERNEL} vmlinux dtbs LOADADDR=0xC2000040 O="${OUTPUT_BUILD_DIR}" it goes through the make process fine and successfully builds the image but fails on the device tree. I get the following message when the build finishes:Kernel: arch/x86/boot/bzImage is ready (#1)make[1]: Nothing to be done for 'vmlinux'.make[1]: *** No rule to make target 'dtbs'. Stop.make[1]: Leaving directory I should probably note that I am using Ubuntu  22.04 and my architecture is x86_64. Any help would be greatly appreciated. Thanks! Carson

Hi,I am debugging STM32MP2 via JTAG and would like to access a process via DAP.  I believe it is possible via the Debug Domain CID (DDCID)that is mentioned in this URL:https://wiki.st.com/stm32mpu/wiki/Resource_Isolation_Framework_overview Unfortunately, I am unable to find proper documentation and steps involved.I would appreciate any advice regarding how to access a resource using DDCID.Thank you.Best regards,Aiyps

Is there a tutorial for newbie? I made my custom board by myself as hobby.the board has switches to select boot 0 and boot 1, boot 2 is tied to ground through 10k resistor. so I could implement boot selector that switches between `00` flashing mode, `01` serial NOR, `10` NAND, `11` eMMC on SDMMC2. and I tested the MPU could run as DFU mode and I could see it in Cube Programmer tool.but I can not get understood how can I flash linux to my board. exactly, I could build linux using yocto but, where should I put my DTS files that generated by Cube IDE?I'm under WSL2 environment to build yocto. unfortunately, I'm not expert of linux kernel :( 

Hi,I am looking to design a board based on a 64-bit ARM processor, with interfaces including USB, Serial, and Ethernet. Could you kindly suggest any development boards that could serve as a good reference for this project?Your recommendations would be greatly appreciated. Thank You

Hello,I use SDL with X11 for now but I want to use it directly with kms/drm kernel driver. I run basic_splash_drm and it works.I don't know how to configure sdl to work together with kms/drm, somebody use it in this way ?Regards,Adrian

Currently, I'm running the M4 core by loading it through the A7 core.Is there any way to make these two cores start independently, without interfering with each other, and only perform communication?

I understand that there would be great performance penalty for the combination of cortex A35 core with octospi psram, but I want to know if this is possible after all? Of course, without great effort on modification of u-boot and kernel code. Just bring up psram in uboot and hopefully cortex A will treat it as usual without significant difference than that of lpddr4. We have a custom-developed product that requires absolutely active state low current as well as PCIE and Linux (for multiple file system on HDD/SSD). Weird enough, may be mmu-less cortex M such as stm32h7 will do the job either, but, we don't trust linux on mmu-less processors. Cortex A will be much better in stability.

Hi,Release notes for STM32MPU ecosystem v4.0.0 mention “Add support of Firmware Update feature�?. Is there anymore information available on this feature? Or is it utilising an existing Yocto swupdate layer?Any additional information would be appreciated. Thanks

Hello, at a glance the 40 Pin GPIO on the STM32MP257F-DK appears to be matching the Raspberry Pi standard, is this correct ? 

 Hi all,I am taking my first steps with the STM32MP257F-EV1, following the "Let's Start" guide on the wiki.At startup, I get a blinking RED LD1, which stops blinking as soon as I connect the CN15/USB_OTG port of the STM32MP257F-EV1 motherboard using a USB Type-A to Type-C cable and press the Reset button, as indicated in the guide (https://wiki.stmicroelectronics.cn/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-EV1/Let%27s_start/Populate_the_target_and_boot_the_image#Populate_the_SD_card).The LD1 LED then either stays ON or OFF, but no device is detected under Linux. I have also tried the same procedure on a native Windows machine, but no device appears (even in Device Manager). As a result, no device in DFU mode is detected by CubeProgrammer, either through the GUI or the CLI interface.Having tried several possible workarounds—such as changing cables, reinstalling drivers and VMs, and reinstalling CubeProgrammer and the supporting software—I analyzed the USB_OTG (DRD)

Hello,I created already several SD-cards images (.raw) using the `create_sdcard_from_flashlayout.sh` script, from both starter kit and Yocto build.Note: Currently working on the STM32MP256 evaluation board.We would like to have something similar with USB:1) Create a *.raw image2) Use `dd` or Raspberry Pi Imager to flash the USB memory3) Select the boot pins on the evaluation board (all-zeros for USB boot)4) Insert the USB memory5) Power-on and wait until Linux is loaded.To my surprise, this process that works fine for sdcards does not work for USB (The card does not boot). This also makes sense considering that :* The script is called `create_sdcard....` and not `create_usb`* The *.tsv are either _emmc_ or _sdcard_But why there is not _usb_ tsv or create_usb script?All the documentation found about USB is by connecting the computer and using the USB link to flash the emmc. This is fine in some environments, but not in others.How to create a bootable OpenST-Linux USB memory ?

Hello,We had to switch out an SD card for eMMC and we kept with SDMMC1. I am aware of having to burn the fuses to get eMMC to default to SDMMC1 which I did. I was able to get it to flash successfully, and now when you switch it to 010 it will boot from SDMMC1 using eMMC. It will then get an error message,     Terminal ready gNOTICE: CPU: STM32MP135A Rev.Y NOTICE: Model: STMicroelectronics custom STM32CubeMX board - openstlinux-6.1-yocto-mickledore-mpu-v24.06.26 INFO: PMIC version = 0x21 INFO: Reset reason (0x35): INFO: Power-on Reset (rst_por) INFO: FCONF: Reading TB_FW firmware configuration file from: 0x2ffe0000 INFO: FCONF: Reading firmware configuration information for: stm32mp_io INFO: FCONF: Reading firmware configuration information for: stm32mp_fuse INFO: Using EMMC INFO: Instance 1 INFO: Boot used partition fsbl1 NOTICE: BL2: v2.8-stm32mp1-r2.0(debug):lts-v2.8.15-dirty(567af710) NOTICE: BL2: Built : 00:51:33, Jan 26 2024 INFO: BL2: Doing platform setup
