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 - ...
Greetings !I am trying to build stand alone u-boot for my "stm32f769 discovery board". But when I initiate make command I am getting the below error .Please help me out to resolve this issue.Error log:------------------------------------------------...
Hello Newbie question here, so i was working for with the stm32mp157 for quite a while now .the boot process for me was flashing an SD Card or a USB stick and boot the thing up. How ever i was wondering if there is a method to load openstlinux or ju...
Hello sir I am using stm32MP157 with ICS-43434 sensor via the I2S interface I am following "https://wiki.st.com/stm32mpu/wiki/I2S_Linux_driver" link to enable the I2S driver in my "make menuconfig" the "STM32 I2S interface (SPI/I2S block) support" ...
Hello everyone,I am trying to replicate this approach to integrate STM32MP1 with an external audio codec. The issue I am facing is that the sub-block SAI-A is generating the bitclock (SCK), while I need it to receive it from the external audio codec....
