I'm working on a design with the STM32MP153 and came across the additional function of PA13 as BOOTFAILN.I can guess what this means but I can't find any documentation on the subject. Don't know when or why this pin gets active. Or is it an input? In...
We have build a device that looks like DK2 but we have a NAND memory instead of SD card and we work on an IO supply of 1.8V instead of 3.3V. We can load the fsbl and U-Boot with STM32cubeprogrammer, but U-Boot resets the usb and the STM32cubeprogramm...
AllI am new to the ST ecosystem.I tried Save as. That saves a 1.6K file with nothing in it.I tried clicking the link and I get a 403 error.How do I download this tar file?Thanks.
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 ...
