Hello!I am using the CortexM4 coprocesor on the STM32MP157F-DK2 to measure multiple ADC channels and update a control loop based on the values. I have set up ADC1 using the DMA2 in circular mode to read channels IN1, IN2, and IN4. I have a buffer set...
Hi Community,I realise that this may be a very newbie question:I have run all the steps as seen on the Wiki,I followed these steps to the letter: https://wiki.st.com/stm32mpu/wiki/PC_prerequisitesFolowed by:mkdir -p st/buildcd st/buildrepo init -u ht...
Hi,I'm searching any information about how exclusive access (LDREX / STREX instructions) is implemented in STM32MP157 silicon. Unfortunately, it seems that ST assumes that this information is obvious.Based on ARM documentation, the synchronization is...
Greetings, I have a few STM32MP1 boards. One of which I have configures the OS on, and custom applications.I copied the SD card and put it in another one. The MAC address is the same. I read an STM article about the MAC address and "fuse sense 0 57...
I built my image to test flutter gallery application from meta-flutter/workflows/stm32mp15. My local.conf file can be seen below:ACCEPT_EULA_stm32mp15-disco = "1" IMAGE_LINGUAS = "en-us" TOOLCHAIN_HOST_TASK:append = " nativesdk-flutter-sdk" CLANGSDK ...
Hi,We are currently working on a project that involves utilizing the STM32MP13X MPU. Our device operates in both ACM and Mass Storage Mode, and we would like to inquire about the process of obtaining a custom name for the virtual serial COM port gene...
Hi,I like to use spidev_test tool:https://wiki.st.com/stm32mpu/wiki/How_to_use_SPI_from_Linux_userland_with_spidev#Installation_on_your_targetI am following this guide for compiling the tool by developer package:https://wiki.st.com/stm32mpu/wiki/How_...
Hi,Is it possible to utilize the PCM1754 DAC as a Sound card with the ALSA Framework on OpenSTLinux?According to the documentation, the PCM1754 functions as a Hardware-controlled DAC, eliminating the need for additional drivers. Therefore, is it nece...
Hello everyone! I am working on a small prototype based on the STM32MP157F-DK2 development board. For convenience, I want to use a GPIO Connector compatible with the Raspberry Pi to power the board (CN2) instead of the USB Type-C (CN6). I have an exp...
We are experiencing an issue where, in approximately 1 in 1000 cases, we don't get a TxRxCpltCallback callback after starting a SPI DMA transfer from an ISR on the ARM-M4 (coprocessor). The transfer appears to have taken place as all the bytes are re...
