HelloI'm considering the requirements and learning process for designing a board with the STM32MP2.I've never done DDR4 routing before—what's the best starting point?Also, is it feasible to design such a board using a tool like KiCad, or is a tool li...
HelloWe are currently attempting to boot both Cortex-A35 cores of the STM32MP257 processor using an SD card. While we have successfully verified that both cores function independently under bare-metal conditions, we are facing challenges in waking bo...
I applied real-time patches to the Linux kernel, but when I measured the RT performance using rt-tests, I found that these two services were affecting it: "stm32mp-calibration.service" "stm32mp-calibration.timer." What is the reason for this?Is it ap...
Hello everyone,I'm working on porting the PCMD3140IRTER codec to the Kirkstone BSP on an STM32MP13 platform. At the moment, I have connected only two microphones (presumably the left and right ones) to the PDMDIN1_GPI1 line.The microphones are Adafr...
Hi,I am trying to test STM32MP257 hash hardware accelerator according to the following article: https://wiki.st.com/stm32mpu/wiki/Crypto_API_overview.I was able to utilize the crypto accelerator using openssl (as described in the article), but once I...
Hi all,I'm currently running the Azure IoT Defender Micro Agent on a Yocto-based image (STM32MP1), and although the logs suggest the agent is working and sending data, no Defender metrics are visible in the Azure IoT Hub portal under Defender Metrics...
I figured out how to build and integrate the Android kernel with my updated drivers. Unfortunately, my eval kit hangs at the ST splash screen before restarting after flashing my device. I run the "flash-device" command mentioned in the wiki: How to ...
Hi,for evaluation I'm running STLinux on a STM32MP257F-DK board currently.I found the Linux console is available on one of the USB-ports with the default configuration of that operating system.Quick question: is that Linux console also available on s...
Hi there,I update the device tree of usart6 of STM32MP257F-DK as below but do not know if it was enabled during kernel.Is it ttySTM0 or ttySTM1 or did not enable and how to check? &usart6 {pinctrl-names = "default", "idle", "sleep";pinctrl-0 = <&usar...
Is it possible to operate USB-C (CN15) and Mini-PCIE (CN13) on the STM32MP257F-EV1 board with end devices at the same time? For example: A USB-C 4 port hub is connected to the USB-C port and a WLAN card is connected to the PCIE port.The documentation...
