Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
Being relatively new to Yocto, I struggle a bit with some issues.I intend to use ADC channels in my (user space) applications, but the channel names seem confusing.Listing /sys/bus/iio on a live system, I can see two ADC devices, device_0 and device_...
Hi,I am unable to see the can0/can1 interface on my brand new STM32MP2 Eval board after re-flashing the Starter-Package(FlashLayout_sdcard_stm32mp257f-ev1-ca35tdcid-ostl-m33-examples-optee.tsv).Previously I was able to see both the interfaces(with ls...
Hi i tried to compile python3-pyqt5 , in my stm32mp157f-dk2 board but failed to compile. in my local.conf file i added this line but again fail.IMAGE_INSTALL:append = " python3-pyqt5"Note: i want any browser just i want to check that URL is working ...
I having some difficulties figuring out details about the ADC usage under Linux, in particular on the MP135F-DK.I located the io driver sources, and the drive itself seems to work:Checking the board user manual, the GPIO pins PC2 and PC3 are routed o...
Hi everyone,I'm currently working on a project to set up the X-STM32MP-GNSS1 GNSS module with my Raspberry Pi 5. The goal is to retrieve GNSS data and potentially other sensor data provided by the module.Specifically, I’m looking for help with Settin...
Hello everyone!I'm getting started with STM32mp157f-DK2. I was able to successfully build images using Yocto as well as buildroot (using stm32mp157c config) and port various command line applications to stm32mp157f-dk2 I'm a trying to develop/port Q...
Hello everyone,I am using the STM32MP135 SoM from PHYTEC, and I’m creating a custom device tree source (DTS) file tailored to our carrier board. I’m having trouble controlling the backlight PWM signal. I’m unable to enable the PWM and enable signal a...
Development environment: buildroot st/2024.02.3Hardware: STM32MP157DAB1 (The schematic diagram is in "SCH-887T227012(A0)-20240815.pdf" in the attachment). The LCD backlight pin of my board is connected to PF7, and I use the STM32CubeMX configuration ...
While I got some experience with Cortex M devices - including several STM32 families - and Linux as host OS, I'm pretty new to asymmetrical dual-core systems like the STM32MP1 devices.What sets them apart is the tight integration of both cores, and t...
Hi Everyone,I have problem with custom carrier and dts. I am using MP135 SoM from PHYTEC and when I add panel backlight property to the panel node, there is no pwm output, but when I comment out this feature from the panel node, the panel backlight w...
