Hi, Community,SDMMC3 is not working on STM32MP157F-EV1 board.I'm not sure what's wrong.I can confirm that SDMMC3_CK/CMD/D0 signals are input and output by osilloscope,but SDMMC_FIFO is empty.The following code is part of the SD_SendSDStatus functio...
I'm working on project that required SPI with DMA .I'm working on STM32MP157C-DK2 board.I am trying to enable CONFIG_SPI_STM32_DMA macro in my config file getting error in zephyr driver due to DMA has not yet been ported on STM32MP1.Any suggestions.T...
Hi! I'm really new to this world, so I'll appreciate the simplicity of your answers.I have an STM32MP157F-DK2 at the University and I need to measure a voltage signal and an UART signal. Can I use only the dual Cortex®-A7 32 bits for configuring the ...
Hello everyone,I'm trying to get started with the STM32MP157 with the STM32MP157x-EV1 Evaluation board by following the exact steps shown here.Everything seems to be running smoothly but when I try to flash the microSD card on the board, something ha...
Hi there,I would be interested to know if there is any guidance or any existing example projects for using the STM32MP1 with an RTOS on the A7 cores. I am interested in the possibility of running an RTOS like ThreadX/SMP on the A7 cores (plus the M4...
Hi, I need help to compile, build and upload a C++ code on an STM32MP157F-DK2 board. Can anyone help me? Thanks
Hi,I am working on this new board, with its Cortex-A7 core, in Eclipse IDE on Windows 10. I understand that this board is mainly developed on Linux.I've looked into STMCubeMP1 package, and some GitHub repos, but I am not able to find the linker file ...
https://github.com/STMicroelectronics/meta-st-stm32mp/blob/kirkstone/classes/fip-utils-stm32mp.bbclassFIP_SIGN_KEY is used to specify the rot key.But if that key is not found (wrong path for example),the bbclass and cert_create silently creates a new...
Hello My borad can bring up from SD card. But can not boot from eMMC. When boot from eMMC. I can't get any message from the console. How can I find the trouble?Thanks
Hi,We are using stm32mp157a processor. We have some confusion for peripheral allocation for 3 cores. We referred document new microprocessor series with enhance performance thanks to its multicore architecture and graphical processor. from wiki.Below...
