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...
Can you please check my device tree configuration?Backlight as a GPIO is working correctly, but when i try to use it as pwm, the pin line is always fixed to low.Inside my .dts:This is my panel definition:panel { compatible = "newkoro,display","simp...
