Hi i want to access remotely my stm32mp157c-dk2 with graphical interface. I am running openstlinux-20-02-19 from starter package. I installed tigervnc (apt-get install tigervnc and apt-get install xauth) and start it by typing "vncserver". But when i...
Hi, i am trying to build linux image along with cortex-m4 firmware which developed using STM32CubeIDE,so for that i have copied a Stm32CubeIDE project under folder DistributionPackage/openstlinux-5.10-dunfell-mp1-21-03-31/layers/sources/m4projects-st...
I have problem to get USB to work. I'm using custom board but I know that USB works because if I boot the board with the delivered image (MyIR) the USB works. I'm using buildroot with the 5.10 kernel and the linux kernel configuration from bootlin gi...
Hi I am working on a drivers for the various peripherals on the STM32. Let me take the GPIO as an example. GPIO BSRR is a write only register that I want to read and I need to read back always 0x00000000. Why?I made a bit-field struct on the whole GP...
I'm now trying to blink a LED on my STM32MP157-DK2 board.I have managed to run and even modify the GPIO_EXTI example, but I'd like to do this from scratch.1) I first created a project using CubeMX and wrote my code in the IDE.It seems that I can't us...
We have custom board design based on stm32157C-DK2. We just ise other LCD panel. We have updated device tree and probe function of panel is called. But in method: ltdc_load it fails to find any panel.bridge when calling: drm_of_find_panel_or_bridge (...
Hello All,We have the STM32MP1xxx-DK. and we had build the image for this board using the steps mentioned on ST wiki to generate the distribution image.We had build st-image-core as its size is less then Weston image.We want not to enable the SPI-5 s...
I'm trying the tutorial on UART (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step3_Introduction_to_the_UART) with an STM32MP157F-DK2 board.I tried defining the USART2 GPIOs with CubeMX as found in the reference document UM2637: DP5 - TX, PD6 - ...
