Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
Dear community, I've used yocto as my workhorse in the past a lot for other processor manufacturers. Now as I'm happily joining the STM world for linux I'm stuck. Maybe it is a too easy to miss question, but which steps I have to take for putting all...
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...
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 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,I have few custom boards with STM32MP257 mostly running PTP related tasks. Once in a while (once in a few days of continuous run) I have noticed the following error in the dmesg (as it seems UART related - I have 4 UARTs enabled in the DT, while 3...
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?
I opened a PR on https://github.com/STMicroelectronics/u-boot.git for a patch that is applicable only downstream, and since I did not receive any response, I contacted Patrice Chotard, who told me to contact you for submitting downstream patches.In a...
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...
