STM32 MPUs

Hi, is it possible to know which is the Yocto configuration (manifest release, DISTRO and MACHINE used, other configurations, etc) used to generate the Starter Package of a board?I think it could be a useful information for everyone. In fact I'm in a situation where the Starter package for STM32MP15 eco 6.0.0 does some operations that fails on an image built using Yocto (Distribution Package) at the same Ecosystem. Thanks in advance Mauro

Is it possible to store keys generated by STM32MP_KeyGen_CLI in TPM and use them by STM32MP_SigningTool_CLI directly, without extracting?

I have been trying to port touchscreen with Stm32mp157c-dk2 without success. Actually, touchscreen has 15 pins but Stm32 has 20 pins and I handled the unmatched pins on Stm in logical way. Rest of the pins match but no screen seen. Do I have to make adjustment in the SW side? Best regards,Halil

I have seen a lot of videos on YouTube where STM32N6 demonstrates incredible AI features such as multiple pose estimation, multiple object detection and multiple object classification at the same time.But I haven't seen anything similar for STM32MP257. So my question is: If I want to start with AI on embedded systems, which one of them two should I use? 

I am working on getting a new board design with a STM32MP153F to boot from parallel SLC NAND flash.  The flash chip is 1 GB, using the FMC interface with 16-bit I/O.  What happens when writing flash via STMCubeProgrammer is the first 2160 bytes of each page are written correctly, but after that byte 2160 is repeated until the end of the page, including through the OOB part of the page.  The page size is 4096 + 256 bytes.As an example, I tried programming ARM Trusted Firmware at the beginning of flash.  If I read back a page from u-boot using the nand dump command, the first 2160 bytes match exactly what is in the file.  The remaining 2192 bytes will contain the same byte, whatever byte #2160 was.  This happens for every page written.  I get the same result if I write a page from the u-boot prompt using the nand write command.For the device tree setup, I am following the STM32MP157A-EV1 as an example.from the output from "nand info", the u-boot fl

Hi,I'm working on layout routing from STM32MC257AAK(Package: VFBGA424) to LPDDR4 (32bit).I have read the "Memory layout rules" in the App-Note AN5724.For a good LPDDR4 signal timing it is usefull to do a "Line-Length-Matching" on the LPDDR4 signals, as noted in the AN5724.Addidtionally:For calculating a good "Line-Length-Matching" from MCU to the LPDDR4, I want to know the internal line length from die to ball (Package: VFBGA424).Could you please provide the internal line length from die to ball (Package: VFBGA424).Reguards

Hi, As I communicated previously I am currently working on upgrading our EV charging solution from OpenSTLinux Ecosystem v4 (Linux kernel 5.15) to Ecosystem v6 (Linux kernel 6.6).The following are my targeted components abd versions to upgrade: Linux Kernel: 6.6-stm32mp-r1 (v6.6.48) Trusted Firmware-A (TF-A): v2.10-stm32mp-r1 U-Boot: v2023.10-stm32mp-r1 OP-TEE: 4.0.0-stm32mp-r1 Now, I started compiling the OP-TEE (4.0.0-stm32mp-r1) and I started getting the following error:  Wrong CFG_DRAM_SIZE 1024MBytes, in device-tree: 512MBytes make[2]: *** [core/arch/arm/plat-stm32mp1/link.mk:17: check_build_variables] Error 1 After doing a bit of looking around I found someone had this issue and the following patch fixed it:  core/arch/arm/plat-stm32mp1/conf.mk flavor_dts_file-157F_DK2 = stm32mp157f-dk2.dts flavor_dts_file-157F_ED1 = stm32mp157f-ed1.dts flavor_dts_file-157F_EV1 = stm32mp157f-ev1.dts +flavor_dts_file-custom = stm32mp157c-cc

Hi, I have made a custom board with stm32mp135f and I have encountered some problems:1. It seems like the stm32cubemx software is not generating .dts file when generating code, and I don't know the syntax for editing the stm32mp135f-dk dts file.2. I looked at the reference tutorial: bootlin embeded-linux-labs, and tried to follow their tutorial but for stm32mp135f-dk evb board but got stuck on:"We can now generate the bl32, dtb, and fip targets with a single command line:$ make ARM_ARCH_MAJOR=7 ARCH=aarch32 PLAT=stm32mp1 AARCH32_SP=sp_min \DTB_FILE_NAME=stm32mp157a-dk1.dtb BL33=../u-boot/u-boot-nodtb.bin \BL33_CFG=../u-boot/u-boot.dtb STM32MP_SDMMC=1 fip all"I tried to change some things that it will work on for stm32mp135f-dk but i got :Makefile:1702: *** "Platform 'stm32mp1' requires BL32. Please set BL32 to point to the right file". Stop.3. When I tried to boot up with yocto linux project i got "error: i2c device not ready" in the pmic check stage because there isn't a pmic in my bo

Hello everyone...I have issue after transmitting data to usb in host CDC the main function will not executes but it will executes after 20 micro Sec i don't know which is causing my main function to stop it's execution, I am using USB host fs with touch gfx, timer. I have enabled the timer interrupt to interrupt for every 500 ms, the main while loop will executes correctly untill the usb data transmitted to device after that the timer ISR and this function static void HCD_HC_IN_IRQHandler   (HCD_HandleTypeDef *hhcd, uint8_t chnum) will executes one after another continuous ( I have checked by changing the interrupt priority also)and making main while loop to stop it's execution I don't know after transmitting usb data why it is happening like this any solution please let me know, and there is no reference for this issue

Hello,I have a custom board based on STM32MP257F-EV1 but with an eMMC (4 bits) connected on SDMM1.I have modify CubeMX configuration accordingly: I have also modify the device tree to declare the eMMC on SDMMC1:&sdmmc1 { pinctrl-names = "default", "opendrain", "sleep"; pinctrl-0 = <&sdmmc1_pins_mx>; pinctrl-1 = <&sdmmc1_opendrain_pins_mx>; pinctrl-2 = <&sdmmc1_sleep_pins_mx>; status = "okay"; /* USER CODE BEGIN sdmmc1 */ non-removable; no-sd; no-sdio; st,neg-edge; bus-width = <4>; vmmc-supply = <&scmi_vdd_emmc>; vqmmc-supply = <&scmi_vddio2>; mmc-ddr-1_8v; mmc-hs200-1_8v; /* USER CODE END sdmmc1 */ }; After booting the board using the USB interface, U-Boot doesn't find the eMMC.mmc rescan: gives nothingmmc list: no answerAnd to further error. Any clues on what's happening here ?

Hello everyone,we are using the STM32MPU Ecosystem v6.0.1 - scarthgap with the provided linux kernel version 6.6.48.We encountered the problem that sometimes after setting up the can0 interface we are not able to send or receive CAN frames. Rebooting the system solves the problem, if it does not appear again when setting up the interface.We mostly encountered the problem on high traffic CAN buses. Resetting the interface with ip link set up/down doesn´t work in most cases. When the setup works we are able to send and receive data normally.

Hi,I'm using an stm32mp257f-ev1 for the first time. I configured the board to boot from emmc: I flashed it using starter package image for fastboot with opteemin image. I noticed that at openSTlinux boot-time remoteproc starts M33 core with USBPD_DRP_UCSI_CM33_NonSecure_stripped.elf.I try to figured out if it's possible to avoid firmware starting at boot-time in some way without deleting it from /lib/firmware.I tried to search if there is something to change on DT or in kernel configuration, but I don't found anything usefulHere's the board boot log concerning firmware starting:[ 11.524092] remoteproc remoteproc0: powering up m33[ 11.529609] remoteproc remoteproc0: Booting fw image USBPD_DRP_UCSI_CM33_NonSecure_stripped.elf, size 144140[ 11.539164] rproc-virtio rproc-virtio.2.auto: assigned reserved memory node vdev0buffer@812fa000[ 11.550597] rproc-virtio rproc-virtio.2.auto: registered virtio0 (type 7)[ 11.551849] remoteproc remoteproc0: remote processor m33 is now up[ 11.564734] Boo

Hi,I am trying to write a LIN master for STM32MP135 running a Yocto Linux. Currently, I am struggling with the break signal. According to the LIN specification, it has to be at least 13 (up to 20) bits long. The device I am trying to talk to is using 9600 baud and the break signal is 1340μs there:A LIN tranceiver is connected to USART1 on my board. How can I send the correct break signal on USART1 on Linux?Thank you in advance!

Hello,Hello,I'm planning to integrate GPS: GNSS1 and install a web browser on an STM32MP157F-DK2, so I'm looking to add layers.Before adding the layers, I thought it would be a good idea to follow this tutorial:https://wiki.st.com/stm32mpu/index.php?title=STM32MPU_Distribution_Package&sfr=stm32mpuI followed it to the letter.I'm running Ubuntu 20.04 with all the required dependencies:https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP135x-DK/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Install_the_SDKI'm up to 80% of the st-image-weston bitbake when an error message appears:```ERROR: st-image-vendorfs-1.0-r0 do_rootfs: The postinstall intercept hook 'update_mandb' failed, details in /home/atem/Distribution-Package/build-openstlinuxweston-stm32mp1/tmp-glibc/work/stm32mp1-ostl-linux-gnueabi/st-image-vendorfs/1.0/temp/log.do_rootfsERROR: Logfile of failure stored in: /home/atem/Distribution-Package/build-openstlinuxweston-stm32mp1/tmp-glibc/work/stm32mp1-ostl-linux-gnueab

Hello,I am currently working on a custom board based on the STM32MP1. In my research, I found that flashing firmware over JTAG is not supported for the STM32MP1 series. Instead, we need to rely on USB or UART for flashing purposes.I came across this related issue on the forum: Flashing STM32MP1 Custom Board Over JTAG.Given this, I am concerned about the security implications of using USB for flashing firmware. Specifically:What security measures can be implemented to prevent unauthorized access or flashing through USB?Is it possible to enforce authentication during the USB boot and firmware flashing process?Are there recommended techniques to encrypt the firmware or restrict access to certain boot modes?And if I use the UART for flashing, then how can I do that? Which combination of boot mode selection switch should I use? Is there any specific documentation for flashing firmware using UART?I would greatly appreciate any guidance or best practices to enhance security when using USB as
