Hello,when configuring a binary semaphore with CubeIDE the parameter initial_count defaults to 1. Is there a way to tell CubeIDE to always initialize this with value 0 for my projects?regardsHerbert
Hello!I'm new at ST!I'm looking to rebuild a project I built on a SBC (rpi4), but now in a board for commercial use and mass production, as for now I bought nucleo64 - F401 for testing.The project consist on connecting a webcam, displaying photos o...
Is stated on STM32MP157 datasheet's boot mode table that the MPU can be booted through UART: – USART2/3/6 and UART4/5/7/8 on default pins Nevertheless, I wasn't able to find which are the default pins for the UART interfaces, on the datasheet or refe...
I am trying to achieve hard real-time under 100us on the STM32MP157f-eval, specifically, on the Cortex A7 dual core.Note: I specifically target the Cortex A7 cores because the M4 is already taken for other tasks which requires much smaller latency.Wh...
Hello,I am currently working with st-image-core in Yocto and attempting to remove some packages that are not necessary for our needs. While I have successfully removed a few packages, some functionality on our board has stopped working because I may ...
I've got the STM32MP135F-DK Discovery kit yesterday; and am going stuck on setting up and using the contributed microSD. Demonstartions are not starting.My Steps so far:- STLink software is installed (WIndows10 pro). - the supplied microSD ist instal...
I have STM32CubeIDE Version: 1.12.0 and a STM32MP157F evaluation board.Created a M4 project and assigned SPI1 to it, generated the code.I then created a function to read a register:const uint16_t opcode = 0xe000; uint8_t value = 0; HAL_GPIO_WritePin(...
First, build the package installed from STMicro's official website with the MACHINE name as "qemux86-64".And is it possible to display about 6 applications such as camera and video playback using demo launcher when started with "$ runqemu"?I look for...
Hi,I have a problem with the DMA seemingly being shut down due to ADC overrun.What I want to achieve: Three ADC channels should be read indefinitely and the values should be written to memory by DMA as soon as they are ready.What's currently happenin...
What are the benefits of using OpenStLinux on STM32MP15 and how does it differ from other operating systems?Thank you in advance for your response :)
