Hi, I’m new to the stm32mp15 series and I’ve been trying to convert code over from a previous microcontroller (stm32f429i-disc1) onto my new MPU. I try to read an input voltage value by running the HAL_ADC_GetValue driver but when I run live expressi...
I compiled the linux kernel uImage and corresponding .dtb file with CubeIDE.Then I mounted the st-image-bootfs-openstlinux-weston-stm32mp1.ext4 and changed the extlinux.conf inside the folder /bootfs/mmc0_extlinux to # Generic Distro Configuration...
Hi Team, We are currently working on a UAV detection project and are in the process of implementing Fast Fourier Transform (FFT) for signal processing. Our setup includes an ADC with a data rate of 1 MSPS (Mega Samples Per Second). We are...
I don't have the knowledge to look at the LCD touch screen specifications to determine if it can be used on my board.I am looking for a 7-inch LCD touch screen that can be used with openstlinux on STM32MP157D-DK1.openstlinux was set up like this:repo...
I compiled the linux kernel with STM32CubeIDE and notice that the linux kernel vmlinux is about 242 Mb.Why so large?Or do I looking at the wrong folder? I'm standing inside the build folder.
Hello I have built the st-example-image-qt using openstlinux(Openstlinux-5.15-yocto-kirkstone-mp1-v23.07.26) to run a qt application for stm32mp157f-dk2 board.I could run the application the application successfully.It would be very helpful to move ...
Hi,I want to create a custom machine for my board. I've found the wiki page "how to create your own machine" but this assumes you create your own layer/machine inside meta-st, but I want my machine to be inside /layers/.I want this outside meta-st be...
I have compiled.OpteeTF-AU-bootLinuxAnd it seems to work well. I have also tried to implement a pre-made OpenSTLinux from the Source files. And it seems to work well too. I haven't got any terminal up and running. I can only see the display output of...
Hi ST Community, @Erwan SZYMANSKI I’ve been working on integrating a Qt example from ~/Qt/Examples/Qt-6.7.2/quickcontrols/imagine into my custom Yocto layer for an STM32 board. I created a recipe for this and updated my local.conf accordingly. After ...
The 'of_device_id' in my module is as follows:static const struct of_device_id gcnano_of_match[] = { { .compatible = "st,gcnano" }, { .compatible = "vivante,gc" }, { /* end node */ } };In the device tree:compatible = "vivante,gc";When usi...
