Using the Distribution Package for STM32MP1 I wrote a simple function to copy some file to the rootfs image and execute fine-tuning commands:my_postprocess_function() { cp -dr /home/osboxes/Documents/overlay/* ${IMAGE_ROOTFS} ln -s /lib/systemd/sys...
Hello,I'd like to test your X-LINUX-AI-CV OpenSTLinux image on my STM32MP157C-DK2 Discovery kit as explained in the following pagehttps://wiki.st.com/stm32mpu/wiki/X-LINUX-AI-CV_OpenSTLinux_expansion_packageDo you provide a ready to flash and use X-L...
We are looking for random access from the linux side as well as DMA capabilities as future add-on.
What is the best mechanism to access shared memory from the A7’s linux user space? I have tried using mmap and was successful at reading shared memory; however, I get memory exceptions when attempting to write. Could it be that I can only write to th...
I'm trying to get STM32MP157C-EV1 board working with the STM32Cube ecosystem.I've had a lot of issues - the documentation isn't well "connected" re. no "getting started" guide with the board. I eventually found the wiki pages - would be *very* useful...
Hi, I'm trying to get DMA2 requests working, using TIM and HAL. Iam using TIM5_CH2 and iam not sure which DMA2 stream should be used here (i use stream1). Creating PWM signal isn't a problem, but i want to change duty cycles (very common problem) by ...
I'm trying execution code:#define DEVICE "/dev/ttyRPMSG0" int main(void) { int fd; struct termios tty; char buf[100]; int len; printf("Opening device...\n"); fd = open( DEVICE, O_RDWR | O_NOCTTY | O_NDELAY ); // read/wr...
I am switching from a classic RTOS/Bare Metal Architecture (like the F4) to the STM32MP1 ecosystem. For that I am trying to generate an interrupt based of a GPIO input.I could not find any specific examples for this in the wiki? Are there any tutoria...
Hi ,I am working with STM32MPU DK2 and Distribution package and have some of basic queries.How do i know which peripheral is connected to which Processor ? where can i get to know about this ? 1.1how do i know which device tree .dts is used ? 1.2 if...
In Getting Started there are links to the SDK and Kernel Source, both links return 403 Forbidden They have been broke since Friday evening, at least that is when I tried to install.
