STM32 MPUs

Hi there, I am working with the STM32MP135F-DK microprocessor and have already designed the user interface in Figma. Now, I would like to move forward with developing this UI. Which tool should I use to implement the UI on the STM32MP135F-DK? If I choose to use Qt Creator, can I use the open-source version for a client project, or would I need a commercial license? Are there any legal limitations or issues I should be aware of? Thanks in advance for your guidance.  

Hello, I'm working on PTP synchronization using the STM32MP257F-DK development board, and I'm encountering an issue with generating a PPS output on a GPIO pin. I'm using Buildroot as the build system, configured with the Bootlin external tree available from : https://github.com/bootlin/buildroot-external-st/tree/st/2024.02.9?tab=readme-ov-file   I want the STM32MP257 board to operate as a PTP slave to an external grandmaster clock. To verify synchronization accuracy, I'm trying to observe the PPS output on the PF4 pin, which corresponds to ETH1_PPS_OUT according to the datasheet, using an oscilloscope.   Here are the steps I followed: Buildroot configuration:  I enabled linuxptp package, I also enabled PTP clock support --> KVM virtual PTP clock in the Device Drivers PTP configuration: I modified the /etc/linuxptp.cfg as follows: [global]verbose                    &n

Dear ST Developer Support,I download the STM32MP2 android 13 images from https://www.st.com/en/embedded-software/stm32mp2droidsta.html#get-software .When I flash the st-android-13.0.0-2024-07-31-stm32mp257f-ev1-emmc-starter images by using STM32CubeProgrammer v2.19 for windows, I would fail on flashing super.img phase.The error message show "Error while reading the file".Would you help me solve this problem.

Heyho,I just checked the MCU selector in CubeMX (6.13), and to my surprise I didn't find any MPU supporting the following:gigabit ethernet (RGMII)FDCAN2 SAIs (I need at least 4 standard I2S/PCM "stereo" channels)The MP series don't have FDCAN.Then I checked the N6, but at least in CubeMX I was not able to configure RGMII with all 4 SAI blocks (1 SAI block as master, the 3 other blocks as sync slaves).That correct ?Thanks in advance! 

Hello,MPU: STM32MP13xxI have a basic que regarding OTP words which are not free for user to use. We are using SSP and for that we need to generate a secret file as per documentation.We want to write OTP values like 3 and 18 but we get this error message in GUI. ex. OTP_WORD_3=0x185b5a00. QUE:- Is it possible to consider OTP 3 during generation of secret file?if NO, what is the other alternative? is the Flasing of OTP via ST Cube Programmer is the only way?(with the goal in mind that we do not want to include more steps in the production scenario) REF:I have already gone through many ST Docs like below-  - https://www.st.com/resource/en/user_manual/um2238-stm32-trusted-package-creator-tool-software-description-stmicroelectronics.pdf- https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer#How_to_fuse_OTP- https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_OTP_management  

We're in the process of upgrading our custom board software to STM32MPU-Ecosystem-v6.0.0, using Buildroot as our build system (buildroot-external-st st/2024.02.9). Our device uses standby mode for low-power operation, and we rely on RTC wakeup and buttons connected to three wakeup pins (PI1, PI2, and PI3) to resume the system. We followed the same procedure as with STM32MPU-Ecosystem-v5, applying the same configuration changes. While we are able to enter standby mode successfully, we are facing issues with resuming from it. Debug logs do not show any errors. We’ve included our OP-TEE and Linux device tree files below. Could you help us identify if there’s anything missing or incorrect in our configuration?

I need a partition as a backup partition for the root file system.How can I add a new partition in stm32mp2?

Hi AllThis has been reported in various forms since 2019:https://community.st.com/t5/stm32-mpus-products-and-hardware/freertos-does-not-run-on-stm32mp1-m4-core/m-p/302468andhttps://community.st.com/t5/stm32-mpus-embedded-software-and/hal-tick-does-not-get-incremented-on-second-debug-session-after/m-p/259405and apparently it was flagged as solved.Yes it was solved in "OpenAMP_FreeRTOS_echo" project but it was never solved in STM32CubeMX code generation for STM32MP M4 processor.Fault was in code that would enable TIMx interrupt before TIMx was initialized so it instance was NULL.Code generated by CubeMX version 6.14.1 and "STM32Cube_FW_MP1_V1.6.0" firmware still generates the same code that ebnables TIMx before TIMx.Instance is set to any value:TIMx IRQ is raised somewhere before TIMx.Instance is set and that causes IRQ service routine to disable TIMx IRQ.We've fixed that by comparing code "OpenAMP_FreeRTOS_echo" in and STM32CubeMX generated code.There enabling of TIMx IRQ was moved furt

Move from MCU forums: STM32MP25 are MPUs - not MCUsHello Experts, I am using  STM32MP257F-DK board and trying to bring up the board with starter package. I followed the steps as mentioned in this link - https://wiki.st.com/stm32mpu/wiki/STM32MP25_Discovery_kits_-_Starter_PackageThe starter package that I have downloaded and flashed - en.FLASH-stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06.tar.gzI was able to flash the SD card successfully as mentioned in section 6.(Note that I have taken care of boot switches accordingly)However, when I restart the board for booting, seems there are issues and does not stop at login prompt. Instead stops or boots in loop. Attaching 2 logs with 2 instances of reset. Kindly help to review and suggest work around if  have missed any steps.~R 

Good morning,fairly new to this mpu family, I did a bit of a research but I'd like to get pointed to the correct procedure to, for instance, change bit 31 of RCC_SECCFGR.This register would allow me for example to modify also PWR_CR1:BDP and PWR_CR2:MONEN registers/bits by unblocking PWR registers protection.Assuming I'm working in a yocto/meta-st environment my first thought is to patch optee-os-stm32mp to modify that register and the PWR registers too since this kind of operations usually require secure context.Question:- Is there any easier approach, or high level approach (eg from uboot or kernel through SCMI) ?Thanks in advance.  

Is it possible to build OpenSTDroid for STM32MP157F? If anyone tried, could you please share the instructions on the build and any learnings would be helpful.

Hi,I am testing TBB on a stm32mp157f-dk2 platform, yocto, kirkstone, sp_min version. I am wondering on the FIP package creation and singing keys.FIP_SIGN_KEY -> is set to my private ROT key.After unpacking the "fip.bin" into separate files i get all the needed components:fw-config.binhw-config.binnt-fw.binnt-fw-cert.binnt-fw-key-cert.binstm32mp-cfg-cert.bintb-fw-cert.bintos-fw.bintos-fw-cert.bintos-fw-config.bintos-fw-key-cert.bintrusted-key-cert.binAnalyzing the all certificates (*cert.bin files) it appears, that the some of them are not signed with the ROT key, as you can see in the "public key" section of the certificate.Analyzing deeper, looking into fip-utils-stm32mp bbclass, I could find, that the cert_create tool is using "-n" option and is generating additional key pair for signing i.e nt-fw.bin. I understand that it generates pair of TRUSTED_WORLD_KEY and NON_TRUSTED_WORLD_KEY, which are used later to follow CoT boot. But I can't find those keys in build dir nor I can'

Dear ST Community,We are working with the STM32MP257F-EV1 evaluation board and using the Yocto Distribution Package for our software stack.Currently, the STPMIC2 is managed entirely by the secure world (TF-A and OP-TEE) on the Cortex-A35 side.Our goal is to access STPMIC2 from the Cortex-M33 core running in non-secure mode with read-only access.We would like to confirm:Is it possible to allow secure access from A35 (TF-A/OP-TEE) and read-only, non-secure access from M33 to the STPMIC2 simultaneously?If yes: could you please share the recommended steps or configuration changes to implement this?If not:We are considering moving PMIC control to the non-secure world (U-Boot or Linux) instead of TF-A/OP-TEE.In this case, could you please provide guidance on how to disable PMIC access in the secure world and enable it in U-Boot or Linux?Also, does U-Boot or the Linux kernel include support for the STPMIC2 driver?Any insights or references to relevant documentation would be greatly appreciate

Will the Linux driver for stm32mp257 automatically set the MAC address based on the chip UID?Or do users need to set it themselves? Why is the MAC address printed using dmesg different from the hardware address obtained from the command?Thank you, looking forward to your reply~

 Hi,We are developing a GUI using MATLAB App Designer and want to deploy it on an STM32MP257 running Yocto Linux.I have a few questions:Can a standalone app generated by App Designer run on Yocto? Does it need the MATLAB Runtime, and is that supported on Yocto?What about exporting it as a web app? Can the MATLAB Web App Server run on STM32MP or Yocto?Any clarification, workarounds, or suggestions for deploying MATLAB-generated applications on STM32MP with Yocto would be greatly appreciated.Thank you in advance!

HelloWe are currently working with the STM32MP257F-DK board and attempting to toggle the GPIO pins on Port Z. However, we have observed that the mode of the pins in GPIO Z remains in Analog mode, even when we attempt to overwrite it. Notably, the other GPIO ports are functioning as expected.We would appreciate your guidance on how to properly activate GPIO Port Z and toggle a pin on this port Thanks & RegardsAkshitha Pattem
