Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
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 thi...
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...
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 ...
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 ro...
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 effec...
Hi,On my STm32MP157c-dk2 with openstlinux-eglfs, I configured in device tree (*.dts file) CAN and works . Now I would like to set pin PH11 as GPIO input.... Please help me how sholud looks my *.dts file, and wher in linux userspace I should find file...
Hi , I built openstlinux-5.15-yocto-kirkstone-mp1-v22.07.27 (openstlinux-eglfs), SDK, configure QtCreator and prepare my first app, but some library mising on target device - STM32MP157F-DK2. Below log, after deploy: id: 'weston': no such user id: 'w...
Hi! I wonder if it's possible to use OpenCV on STM32MP2 and configure so the neural networks use the NPU for faster classification and detection. Thanks
Hi everyone, I was finally able to get to the kernel and use the shell using the sd card (yay!). However, we want to boot from the emmc (sd card was for dev purposes but we want only emmc) and I am running into an issue. Here is my boot log from boot...
Hello,to retrieve the temperature in the M4 domain I use the documentation RM0436, page 1571 (description) and DS12505Rev6 page 209 (characteristics)Q1: what adc resolution is to be used to be compliant to the reference values (calibration values) th...
