STM32 MPUs

Hi,I have a small problem with the RTC on STM32MP153. From hardware point of view I'm able to see sine waveform on the resonator 32.768kHz which is connected to PC14, PC15.I use the Openstlinux - kirkstone (openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23).I configure rtc section only in tfa file  clocks { /* USER CODE BEGIN clocks */ clk_lsi: clk-lsi { clock-frequency = <32000>; }; clk_hsi: clk-hsi { clock-frequency = <64000000>; }; clk_csi: clk-csi { clock-frequency = <4000000>; }; clk_hse: clk-hse { clock-frequency = <24000000>; }; /* USER CODE END clocks */ /* USER CODE BEGIN clk_lse */ clk_lse: clk-lse { st,drive = < LSEDRV_MEDIUM_HIGH >; #clock-cells = <0>; compatible = "fixed-clock"; clock-frequency = <32768>; }; /* USER CODE END clk_lse */ /* USER CODE BEGIN clk_hse */ /* USER CODE END clk_hse */ }; ... &rcc{ status = "okay"; /* USER CODE BEGIN rcc */ /* USER CODE E

There's a problem enabling QuadSPI in CubeIDE. After enabling QSPI and generating the code, compile errors occur.Here are the issues I've identified:XSPI_HandleTypeDef is not defined.There's no define related to QSPI (or XSPI) Enable in the stm32mp13xx_hal_conf.h file.Declarations for HAL_XSPI_MspInit and HAL_XSPI_MspDeInit functions' code are missing in the stm32mp13xx_hal_msp.c file.HAL_XSPI_MODULE_ENABLED is not present in stm32mp13xx_hal_conf.h. Thank you for your help.

Hi Team, We're currently facing challenges enabling HS200 mode for the eMMC in our STM32MP135 project. We'd appreciate your assistance in resolving these issues: Clock Speed Discrepancy: In CubeMX, we've configured the SDMMC1 and SDMMC2 clocks to 200 MHz. However, the observed output clock for the SDMMC (eMMC) interface is only 130 MHz. Delay Block Implementation: The reference manual mentions the use of a delay block. Could you please elaborate on how to implement this block to achieve the desired HS200 mode? If I set vmmc and vqmmc to 3.3V and 1.8V in the DTS, I encounter errors during the flashing process. Error messages are displayed while flashing. For your reference, we've attached screenshots of our current Device Tree Source (DTS) configuration and the terminal output. Please review these and advise if there are any missing elements or configurations. Thank youRaj

Currently, I am testing QuadSPI.Is it correct for the output to include Command / Address / Data?I want to output only Data. While I can remove the Address through settings, I couldn't remove the Command.Is it possible to output only Data?

Hi,I am using an STM32MP157_SOM interfaced with an LCD-OLinuXino-7TS screen. I have activated the splash screen for U-Boot and psplash in the kernel. The U-Boot splash screen works correctly. However, after the 'Starting kernel...' message, the screen goes black until the psplash is launched (17 seconds with the splash screen). I have included parts of the DTS for U-Boot and the kernel. Is there a way to keep the U-Boot screen displayed until the psplash launches? LCD power enable and backlight stay enabled. u-boot dts : backlight: backlight {compatible = "gpio-backlight";gpios = <&gpiod 13 GPIO_ACTIVE_LOW>;default-on;status = "okay";power-supply = <&vdd>;};panel-rgb@0 {compatible = "simple-panel";backlight = <&backlight>;reset-gpios = <&gpioa 14 GPIO_ACTIVE_HIGH>;enable-gpios = <&gpiof 13 GPIO_ACTIVE_HIGH>;status = "okay";port {lcd_panel_in: endpoint {remote-endpoint = <&lcd_display_out>;};};display-timings {ti

Hello everyone,I made a yocto based build using stm32mp1. After compiling, I followed these steps: I created 5 different partitions in the SD card. These are as follows.  I uploaded the following files to the partitions I created, respectively.sudo dd if=arm-trusted-firmware/tf-a-stm32mp157d-dk1-sdcard.stm32 of=/dev/sdb1sudo dd if=arm-trusted-firmware/tf-a-stm32mp157d-dk1-sdcard.stm32 of=/dev/sdb2sudo dd if=fip/fip-stm32mp157d-dk1-fastboot-sdcard.bin of=/dev/sdb3sudo dd if=st-image-bootfs-poky-stm32mp1.ext4 of=/dev/sdb4 bs=1Msudo dd if=core-image-minimal-stm32mp1.ext4 of=/dev/sdb5 bs=1MLater, when I connect to the DK1 board, I get the following error.When I examine the Flash layout files, I think it does this because it cannot find the FWU_MDATA files. But I don't know the size of the partitions I allocated for FWU_DATA and what type they will be (Linux file system or microsoft basic data). Can you help me with this? Which partitions are missing and what should their file typ

Hello,How to clean all demo applications from OpenSTLinux, which came with the starter-package?

Hello,I am currently working on a project with the STM32MP131FA.We are testing various peripherals and modules on our board.When creating a project with STM32CubeMX, we encounter some issues. Therefore, we sometimes download and test DK examples on our board for comparison.For instance, we have successfully tested DDR initialization by modifying the PMIC I2C part.However, when running the USB example UX_Device_CDC_ACM, it does not work correctly at the Vector table.Could you help identify where I might need to make modifications?void Vectors(void) {__asm__ volatile(".align 7 \n""LDR PC, =Reset_Handler \n""LDR PC, =Undef_Handler \n""LDR PC, =SVC_Handler \n""LDR PC, =PAbt_Handler \n""LDR PC, =DAbt_Handler \n""LDR PC, =Rsvd_Handler \n""LDR PC, =IRQ_Handler \n""LDR PC, =FIQ_Handler \n");

Hello all,I'm working with STM32MP135F-DK board and GC2145 camera that comes with it. My main purpose is to get the image and save it. I tried to use the following documents for this:https://wiki.st.com/stm32mpu/wiki/STM32MP13_V4L2_camera_overview#Grab_a_raw_framehttps://www.st.com/resource/en/application_note/an5478-stm32mp13x-lines-interfacing-with-a-mipi-csi2-camera-stmicroelectronics.pdfI didn't know how to do the "3.1-kernel configuration" step in the first link. So I followed the links below:https://wiki.st.com/stm32mpu/wiki/Menuconfig_or_how_to_configure_kernelAfter this link, I went to the following link:https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_PackageAfter installing some packages here, I went back to the "menuconfig-how to configure kernel" link, and here I got stuck on the following step:I have the specified files but I don't know in which directory I should run the make config or make menuconfig commands.To be honest, I am new to embedded Linux and my ma

HiI have the same problem as described in the topic below:https://community.st.com/t5/stm32-mpus-products/usb-composite-in-stm32mp157c/td-p/142734I tried the solution from the above link. I see that I can set up several USB gadget devices, like NCM Ethernet + multiple ACM serial. But it doesn't work, e.g. I can set the 'usb0' interface link to 'up' and set the IP address to it, but I can't ping it from my laptop. At the same time, I can ping it when I have ONLY NCM Ethernet (without ACM devices).The same situation with ACM devices, it works only if I have only one. If I have more than one USB gadget device (at least 2), serial port either is always busy or transfer works only in one side (from device to laptop).I'm working on STM32MP135 Discovery kit (STM32MP135F-DK) with mickledore yocto provided by ST (https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package).My otg config:usbotg_hs: usb@49000000 {compatible = "st,stm32mp15-hsotg", "snps,dwc2";reg = <0x49000000 0x40000

Hi everyone, I have been trying to get Docker running on the STM32MP135F-DK for quite some time now and have been running into some issues. I originally built an image for the STM32MP135F-DK with the Mickledore release by following this tutorial: Link. However, I kept running into issues trying to get Docker to run correctly. I was able to create an image successfully and install Docker-CE, however it seems the meta-virtualization layer is no longer supported for Mickledore so getting Docker to run correctly with Mickledore does not seem to be possible anymore. I can install Docker-CE and run docker commands, however starting the Docker "hello-world" container I get an error saying "ERROR: http: invalid Host header" after downloading the container. I know we have configured the kernel correctly (we have created images with the Dunfell branch on the STM32MP157 series and got docker to run containers correctly) so I do not think that is the issue. I saw that Kirkstone was still

Dear All,I want to add some packages like zip, nmap, net-snmp, gdb and apache2 to default package.Could you guide how to add some packages to default package to build kernel?

Will you also review the newly designed stm32mp157 artwork file?

Hi,Since Ecosystem 5 OP_TEE is mandatory.We have previously used SP_MIN which is not supported anymore.The change from SP_MIN to OP_TEE costs us approximately an extra second in boot time, we need to limit this as much as possible.I came across in the wiki here - "STMicroelectronics provides OP-TEE support that also embeds a secure monitor on Armv7. It can be replaced with a trusted OS or another trusted environment execution (TEE).".I was wondering, is it possible to change OP-TEE to a different lighter vendor? If so, is there a document describing the steps necessary?Thanks in advance  

Hi, "I'm using an STM32MP157F-DK2. I'm struggling with the serial connection between my Linux host and my target board (STM32MP157). I'm using the command 'minicom -D /dev/ttyACM0', but I've been waiting for more than 2 hours for the connection to be established, yet it's still not connected.What can I do to connect to the target device?"
