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...
Dear ST team, Hope you're doing well.We have developed a custom board based on STM32MP151 with emmc. Currently, we are using STM32MP151 for flashing. The problem is each flash is taking around 15 minutes time and it will be a critical issue in our p...
error is logged as > Label or path sram not foundThe DTS file at the failing line reads &sram{ dma_pool:dma_pool@0{ reg = <0x50000 0x10000>; pool; }; }; I'm assuming this is to specify where the SRA...
Hi,I have a problem with hanging up my board occasionally when an issue from the console reboot.I read about and the internet says this is a problem with the EMMC memory's power cycle.So I followed by a linkhttps://github.com/orangepi-xunlong/openwrt...
