STM32F157F-EV1 board and RaspberryPi 7-inch LCD were connected using B-LCDAD-RPI1.However, the LCD does not output.The image is in use by building Yocto st-image-weston and flashing it to the SD card.How do I operate the Raspberry Pi LCD?
Hello ST community,For a project, we use the STM32MP157F-EV1 where we are trying to implement the secure boot chain. For this, we have to generate a FIP package that contains all required certificates. In the ST wiki two methods are proposed :One usi...
I am a beginner with STM32MPUs and I've been trying to follow the example: How to stream camera over network (can't add links because I'm a new member but it's in ST Wiki)I'm trying to stream the video from an USB Webcam connected to the STM32MP157F-...
Hello, For generating the I2C5 init code, I took the I2C4 discovery kit example and modified it accordingly.Unlike in I2C4, I see the banks of the I2C_DATA and I2C_CLK are different I2C5: ( GPIOz and GPIO D)for I2C4 (GPIOZ): in the I2C4 code generati...
