Hi:Recently, while developing an application on the STM32MP257, I tried to remove Weston. After removing the weston-start application, other apps could no longer be displayed. Additionally, when using modetest to check, I noticed that the CRTC sectio...
Hi,I have a custom board with STM32MP151 and have been trying to run it for quite some time. I have been fixing one mistake after another. But now I can't solve the last problem: [13:11:36:338] F/TC:0 0 probe_driver_node:436 Probing stm32-tamp on nod...
Hi:Recently, I need to display the logo during the Kenel phase. I have tried adding the following configuration, but still cannot see any logo when the kernel starts. How can I enable the logo to be displayed on the ST platform (drivers/video/logo/):...
Dear ST Community,I am currently modifying an existing schematic to meet my specific requirements for the STM32MP135 Linux board. In line with these hardware changes, I would like to reconfigure and modify the Linux kernel image file accordingly. I n...
I am a newcomer and not very good at using Linux. I hope to try running the model on the device. I am using a third-party development board. Is the tutorial on the official website applicable or can I use an API

Hi,I am using internal temp sensor DTS and have critical trip point of 120 C configured. I wonder how interrupt work in this case? Where and how should it be handled? Are trip points the only cases when interrupt from DTS happens?
Hello forum;I needed help to do some SI simulation on ESDALC6V1-5M6 and LD39150PU33R Hyperlynx/Altium Designer SI simulator. Hence my question is does this ibis model exist? If yes where can I download it?
hello,st friends. My board use TIM2_CH1 pwm to drive a led.dts configure as:but the led can not light on.use these command byw: I use gpio test led hardware is ok
Hi,is it possible to swap the DSI lanes so that lane 0 becomes lane 1 and the other way around? This would simplify routing on our PCB. I've found there are configuration bits in the DSI_WPCR0 register for custom lane configuration (SWDL0 and SWDL1),...
