Hi all,I have been trying to get DSI interface on a custom board using STM32MP1.The device tree exactly done as given here : LInk.I do have DK2 kit , which i probe I am able to see the signals at DSI PHY even if display is not connected.In case of my...
I'm working on a driver present in the Linux 5.4 kernel. In RS485 communication I receive everything I send, without being connected to another device to return what I sent.I use the command echo -e "Test" > /dev/ttyLP0 for the submission.I know that...
I am trying to configure the TIM2_CH4 to capture mode on EV1 board so I can sense a fan speed from a PWM fan but I keep getting cat: read error: Connection timed outI have configured the timer as follows: &timers2{ pinctrl-names = "default", ...

Hi!I ordered now a STM32H747I-DISCO board. Have looked in the source tree from U-Boot (ST fork and mainline). I know there is a support for STM32H743I-EVAL board. Wondering why there isn't a support for the STM32H747I-DISCO.Generic question:Has someb...
Hi,I'm using OpenST-linux version 4.9 on a STM32MP157c-ev1 and I wrote a simple script to run my firmware for Core M4. I would like to know how I can make the script run automatically after system boot.Here's my script if could of any help for answer...
SAI2 Block A configured as a MasterTX and works. Fs configured for 48KHz, bit clock configured as 64*Fs and MCLK as 256*MCLK. I've verified these signals are sent to the audio codec which is configured as a slave (receives MCLK, SCLK, LRCLK (Fs)). Th...
Hi dears I wish you a good day ,I am working on my bachelor graduation prohect which is ( an overcurrent protection relay design ) and I using an STM32MP1 to have all the functions and required controlling inside it. And I want to add a communicatio...
