Dear experts, why, under the same configuration for heterogeneous core communication, in the generated code, the debug section of the routine's initialization functions of IPPC and OPENAMP can be accessed, but the ones generated by ourselves cannot?T...
Hello everybody,For my project, I need to display (LVDS output) an HMI that contains external video streams.I plan to use LTDC layers in order to perform plane composition with the hardware block (for example, HMI on plane 1, RTP video on plane 2, an...
I'm trying to add the linux "gpio-poweroff" function to the distribution package. I've added the following to my device tree:gpio-poweroff { compatible = "gpio-poweroff"; gpios = <&gpioe 1 GPIO_ACTIVE_HIGH>; timeout-ms = <3000>; };The kernel/devic...
I'm bringing up a very simple board that uses STM32MP135 with LAN8742A-CZ-TR Ethernet PHY as on the eval board. Unlike the eval board, however, I clock the PHY directly from the SoC: PA11/ETH1_CLK from the STM32 is connected to XTAL1/CLKIN on the PHY...
Hi im working on stm32mp257f-ev1 and the "edt,etml0700z9ndha" display,Im unable to decode the logic why the back-light enable gpio only gets high when there is a display connected in the lvds port, what logic is used to detect the lvds display connec...
Hi Team,I am using the following method to enable password protection for both SSH and serial login.I added the below configuration in local.conf:INHERIT += "extrausers" EXTRA_USERS_PARAMS += "\ usermod -U root; \ usermod -p '\$6\$ao/KaHyZbsg...
According this article: https://wiki.st.com/stm32mpu/wiki/GPU_internal_peripheral. It is not supported configuration for OpenSTLinux BSP. Can I manually assign or enable GPU with the x-linux-qt image? If yes, how?
Hello.Is there any way to exclude some GPIOs from Linux, when I control them from M4 core and I don't want to give an ability to control them from Linux apps? I would like to exclude e.g. PG12. I tried this, which should be exactly for such use:&gpio...
Hi,Could you share documentation or examples for running quantized foundational models (e.g. Google Gemma) on the STM32MP257F-DK—first in Python, then in C/C++ using the STM32MP2 NPU? Specifically:Does the STM32MP2 NPU support transformer-based archi...
Dear Team,We are trying boot Uboot(V2025.04) on a Custom board with STM32MP157AAA3 Processor.But while booting we can see that code hangs at WDT: started Watchdog@5a002000 with servicing every 1000ms (32s timeout) and restart after sometime.We have a...
