STM32 MPUs

Hello everybody,i use "meta-st-x-linux-qt"  with "meta-qt6" on STM32MP157https://github.com/STMicroelectronics/meta-st-x-linux-qtwhen I use "QMediaPlayer" to play an audio file it gives me the following error: could not load multimedia backend "ffmpeg" QtMultimedia is not currently supported on this platform or compiler. Aborted (core dumped) if I understand correctly, "ffmpeg" would be missing on my platform, how can I add it to yocto when generating it?Thank you very muchLoupi

I am in the process of starting a board with an STM32MP153CAB processor, unfortunately due to an error in the design, the I2C4 interface is not available( i2c4 is connected to the PMIC by default). I am able connect I2C2 directly to the PMIC, but this interface is not supported in TF-A, other solution is connect I2C6 using wires. The question is how to force using of i2c6 or i2c2 instead of I2C4 by dts config files (Yocto kikrcore).

I am developing a new board and would like to know if the STPMIC25 is recommended over the STPMIC1 as a PMIC for STM32MP157 MPU.Which one should I choose?Thanks. 

According to this article the signing tool is a part of STM32CubeProgrammer. I need a signing tool during my Yocto build to be able to build signed images. The best way to guarantee a reproducibility of the build is to launch it in a dedicated container (to make sure the host system is the same on all developer / CI machines).So the few questions are:I can't automatically download only the signing tool, can I? The download of STM32CubeProgrammer package requires for me to accept the license.It seems that STM32CubeProgrammer installer doesn't have any command line options. I would like to at least have unattended installation, automatically accepting the license and setting installation path in a non-interactive way. CubeProggrammer installation manual doesn't mention any. All that is required, for example, during 'docker build' execution.Is there an open source signing tool alternative?

While reviewing the schematic of the STM32MP157 EVAL development board, I came up with the following questions:I apologize in advance if the translation isn’t perfectly accurate as I used a translator.The Line Out JACK (CN4) outputs via coupling capacitors from SPKOUTLP (A2, B3). Why are the Line Out pins (B5, B4) not used instead?The codec supports differential audio output, but why is the negative pin not connected? (Wouldn’t it prevent distortion if the signal is converted to single-ended using an op-amp before connecting to the audio jack?)Why are the Speaker Out pins used instead of the Line Out pins? (Is it because of the built-in amplifier, or is there another specific reason?)I have some additional questions regarding the microphone circuit. (Sorry if these are silly questions!)If I am using a digital microphone (IMP34DT05TR), can I apply a different power supply (3.3V) to the microphone module instead of the MIC bias voltage from the audio codec (A7, B6), and leave the bias pi

I am trying a simple CM33 ELF test. This one just has the STM32CubeMX boilerplate for the CM33 (non secure). I added a toggle on GPIOJ[6]. I stripped out a ton of the inits leaving just the GPIOJ[6] and pin toggle. after the seq below LED3 *does* toggle.But... the system watchdogs after ~30secs. How to kick off a CM33 program and not have start hang?Is there some way the CM33 can tell the CA35s to keep going and leave the CM33 running?echo -n /home/hedley > /sys/module/firmware_class/parameters/pathecho start >/sys/class/remoteproc/remoteproc0/state   <<<<<<<< this will not return to the prompt... hang./home/hedleylrwxrwxrwx 1 hedley hedley 27 Jan 20 16:50 rproc-m33-fw -> test_mp2_CM33_NonSecure.elf-rwxr-xr-x 1 hedley hedley 3216664 Jan 20 16:51 test_mp2_CM33_NonSecure.elftnxHedley 

Hello, I would like to know if it is possible from a stm32mp135-dk1 card to put a game emulator for example NES games, gameboy,... if so how to do it? Can we start from the image that we can generate on stm32mpu ecosystem (openstlinux under yocto)How can i do it ?

There is a problem about PLL3 while using engineering mode on STM32MP157A-DK1 board. By STM32CubeMX, I configed the clock of M4 core, using PLL3P to get 209MHz, generated code, rebuild it and entered the debug mode. But it shut down and get into an Error. I debuged it bt step, found that it failed in the intial function HAL_StatusTypeDef HAL_RCC_OscConfig(RCC_OscInitTypeDef *RCC_OscInitStruct). When it get to configure PLL3, failed and enter the error. So what I missed? May someone can help me. Thanks! 

Hello, I'm trying to remove the packages which is not required to free up the memory.I tried modifying the layers/meta-st/meta-st-openstlinux/recipes-st/images/st-image-weston.bb file with the below code, But it couldn't help.Here i tried to remove the alsa packag.#To Disable the ALSA PackageIMAGE_INSTALL:remove = "\alsa-conf \alsa-plugins \alsa-state \alsa-state-script \alsa-state-stm32mp1 \alsa-states \alsa-topology-conf \alsa-ucm-conf \alsa-utils \alsa-utils-aconnect \alsa-utils-alsabat \alsa-utils-alsactl \alsa-utils-alsaloop \alsa-utils-alsamixer \alsa-utils-alsatplg \alsa-utils-alsaucm \alsa-utils-amixer \alsa-utils-aplay \alsa-utils-aseqdump \alsa-utils-aseqnet \alsa-utils-iecset \alsa-utils-midi \alsa-utils-scripts \alsa-utils-speakertest \"How can I remove the package. Thanks and Regards,Ezvan.  

1. Does the STM32MP157D-DK1 board have 3.0 USB ports? Does the USB C connector have USB 3.0 capabilities?2. If no to the questions above, what STM32MP board should we use if we want to have USB 3.0 capabilities?

I'm trying to get SecureBoot running on STM32MP157.After opening and reading about 30 pages of your wiki and basically following [1] I was able to create keys and convinced yocto into generating "*_Signed*" files.Sadly I then got confused with publicKeyHash00.bin and publicKeysHashHashes.bin and uploaded the latter one into my OTPs (all instructions always point to publicKeyhash.bin - never the correct file name). My bad.When I now try to upload new signed images onto the emmc, the process outputs: NOTICE: Bootrom authentication failed NOTICE: BL2: v2.8-stm32mp1-r1.0(release):lts-v2.8.6-dirty(ff0bd5f9) NOTICE: BL2: Built : 17:57:15, Apr 21 2023 NOTICE: TRUSTED_BOARD_BOOT support enabled ERROR: BL2: Failed to load image id 1 (-80) Authentication in boot ROM fails as expected. That's okay. But from the last line I think loading of the fip image also fails.Page [2] says "The process ends with error authentication error -80 in case of incorrect provisioning.".Does this mean the b

Where can I find the STM32MP25_CM33.svd file?

Hello,I am working with STM32MP135F-DK and Yocto (Kirkstone), using poky, meta-openembedded, meta-st-stm32mp layers. I am creating my custom image for the board. I want to implement OTA to my board and I have chosen swupdate package to achive that. I have also chosen to follow the "dual-copy" stategy. And that's where I had to start dealing with U-boot, it's environment, and environment variables. I am certainly a beginner in Yocto and Embedded Linux. I did some research, I have followed U-boot bootcmd all way down through all ST scripts there, and as far as I can understand:configuration (setting CONFIG_...) of U-boot and environment variables is done in .patch files located in meta-st-stm32mp/recipes-bsp/u-boot/u-boot-stm32mpthere is a boot.scr.cmd in stm32mp-extlinux folder but it should not be used in production, it's there to handle all availiable dev-boards and types of storagewhen my board boots it uses mmc0_extlinux/st32mp135f-dk_extlinux.conf file.

Hi,Migrating to STs ecosystem v.5.1.0 from v.3 right now and having an issue with M4 where remoteproc is unable to attach to running M4 and consequently fails. From what I can see in the logs there is a timeout while waiting for the resources, in fact only m4_dma2 becomes available (see attached log dyndbg.txt).I am following this guide How to assign an internal peripheral to an execution context - stm32mpu to configure DT files (see attached DT.txt). As you can see all corresponding soc peripherals have been disabled and all m4_ peripherals enabled, but for some reason only dma2 gets probed. What am I missing here?Thanks!

Hi,Is there any example showing how to configure a simple GPIO line using DeviceTree? I would like to set the pullup/pulldown or open drain and then use the /sys/class/gpio to read or write the value. The only example I can find is the GPIO setting for particular peripheral and not for standalone input/output pin.I have added the following section to the &pinctrl in my device tree but I think it has no effect on the pins configuration. gpio_pins_mx: gpio_pins_mx-0 { u-boot,dm-pre-reloc; pins { u-boot,dm-pre-reloc; pinmux = <STM32_PINMUX('D', 11, GPIO)>, <STM32_PINMUX('C', 0, GPIO)>, <STM32_PINMUX('B', 7, GPIO)>; bias-pull-down; }; };Thank you,Chris

Hello ! I am developing a STM32mp257FAI3 board.Does STM32mp257FAI3 support ubuntu 20.0.4 operating system?

Hi ST,Komal here, I want to purchase STM32MP157D-DK1 my requirements include:should support Linux full OSEthernet phyRAM 4GBso my question is will this board support full linux OS and other requirement of mine ?if not suggest a board according to my requirement.if the board suits good then kindly suggest which series of the board i will have to go for. Waiting for your quick response. Thank you

Hello,for flashing my STM32MP135F-DK board I am using STM_Programmer_CLI with my .tsv file. Example command and my tsv file:sudo ./STM32_Programmer_CLI -c port=usb1 -w path/to/my.tsvIs there a way to explicitly set partitions UUID for rootfs-a and rootfs-b during flashing?I've noticed that when I name a partition with rootfs then it gets UUID of e91c4e10-16e6-4c0e-bd0e-77becf4a3582, as described in the wiki . But when having rootfs-a and rootfs-b, then those partitions get some other UUID, and the boot stops because rootfs UUID is not e91c4e10-16e6-4c0e-bd0e-77becf4a3582.I need the rootfs-a and rootfs-b UUIDs to be constant, to manage FW upgrades.

Is there a recommended minimum SMT package size and power rating for resistor R4 (8R2) please?

We have a board with PMIC attached to I2C2. I've followed the directions in https://wiki.st.com/stm32mpu/wiki/PMIC_hardware_components#TF-A to add the i2c2 node to the device tree. I have the I2C2 clock set to use HSI. No matter how I configure the clocks I can't get I2C2 to be initialized properly. Here is the message I get in TF-A:ERROR: I2C clock rate is 0ERROR: Cannot initialize I2C 40013000 (-22)

Dear ST Team,The kernel recipe in Scarthgap branch has following packaging:FILES:${KERNEL_PACKAGE_NAME}-image += "boot/ ${KERNEL_IMAGEDEST}"FILES:${KERNEL_PACKAGE_NAME}-imagebootfs = "boot/*.dtb boot/${KERNEL_IMAGETYPE}"Which has following side effects.The base class in openembedded-core layer defines packaging in meta/classes-recipe/kernel.bbclass as followsFILES:${KERNEL_PACKAGE_NAME}-image = ""FILES:${KERNEL_PACKAGE_NAME}-dev = "/${KERNEL_IMAGEDEST}/System.map* /${KERNEL_IMAGEDEST}/Module.symvers* /${KERNEL_IMAGEDEST}/config* ${KERNEL_SRC_PATH} ${nonarch_base_libdir}/modules/${KERNEL_VERSION}/build"By placing everything from the "boot" directory into the image package you hide "dev" package completely and it becomes empty.The "imagebootfs" package repacks devicetrees, thus hiding kernel-devicetree package from openembedded-core layer. If you need custom package for any reason, I suggest you set run-time dependencies rather than re-arranging the files. FTR, devicetree packaging is do

Hello, I am having an issue when I try to download the Developer package in the wiki. I am using this link (https://wiki.st.com/stm32mpu/wiki/STM32MPU_Developer_Package#Installing_the_Starter_Package) in the 5.2 section, there, it redirects me to (https://www.st.com/en/embedded-software/stm32mp1dev.html#get-software). In the last link, when I try to download the file, it downloads the wrong file, since it downloads the SDK instead of the Developer package. Probably there is an error in the API and it gets the wrong file. Does anyone else experiences the same issue?
