For Rockchip RGB panel this link to refers to device tree binding of panel-dpi, (MIPI-DPI), https://wiki.st.com/stm32mpu/wiki/Display_panels_hardware_componentsSeveral RGB panels are also listed in panel-simple.yaml. Which devicetree bindings one...
I have an STM32mp135f-dk board that I have been using openstlinux-6.1 to develop images on.For my board, I made a custom device tree "iris.dtb" which I intend to use instead of the default "stm32mp135f-dk.dtb".I ran into an interesting issue where u-...
I'm trying to run my application compiled and linked for DDR on STM32MP135F-DK. Following the wiki istruction it's necessary preliminary to run the DDRInit project on SYSRAM that initialize the DDR and then execute my custom program.When I execute th...
Hello,I have compiled a custom image to run on the M4 core on my stm32mp157f-dk2. I generated the code using STM32CubeMX. I am able to build it fine but am having issues launching it on the m4 core. Here are the commands that I run. echo executable.e...
Custom board. with STM32MP157 Objective is the use spidev to test and make transfer over the SPI2 bus. Problem: no ls /dev/spi*Added SPI2 using cubeMX to a project without these and generate the files.Compare the files generated with files generated ...
Hi,My LCD display format is RGB666, I removed the "LCD_R0,LCDR1, LCD_G0,LCD_G1,LCD_B0,LCD_B1" in file "stm32mp15-pinctrl.dtsi", and recompile my device tree, then upload to my board. I tried to use the LCD_R0 as GPIO with command: gpioset gpiochip7 2...
Hello,is there any example how to configure LTDC device tree entry for RGB display ?Documentation is unclear on that, only MIPI mode is quite well documented.RegardsArkadiusz
Do the SPI interface need an entry in the SCMI file, as what I2C requires to work ?if yes, So far could not find the exact entry for SPI2. According to the SCMI wiki not, but you never now. (:-))
Kernel tree does not assign any driver to pin PZ2. After gpioset -c gpiochip11 2=1, the pins goes actually high (from low) but the gpioset program stalls. SSH at that moment into the device shows: line 0: "PZ0" input line 1: "PZ1" input line 2: "PZ2"...
Custom SMT32MP15 board connected via the micro USB to a host PC. This board has HDMI via an RGB to HDMI chip but here PA10 is only used for USB OTG-ID) (there was another post on this about HDMI). Build kernel from ECO 5.0. The Gadget functions wor...
