I have a successful emmc image running on my STM32MP157FAD. However, fw_env.config is incorrect. This is my first project using FIP and I'm a little confused where the uboot environment variables are now located.Partition Layout:/dev/mmcblk1p1 3...
I check STM32MP157F-DK2 schematic. Transmit Channels(ETH_TXD0..ETH_TXD3) isn't have termination resistor. Receive Channels (ETH_RXD0..ETH_RXD3 ) is have termination resistor. But you add termination resistor on Transmit Channels in your application ...
Hi STM-Team,We are facing problem while using multiple USART in parallel on STM32MP153C running Linux kernel v5.4.Our application contains two separate threads communicating on two separate RS485 ports in parallel at every ~10ms. After further debugg...
Hi STM-Team,We are trying to enable/configure HS200/HS400 mode in eMMC on STM32MP157F-EV1 evaluation board.We are using the stm32mp157f-ev1.dts device tree and we have configured the eMMC node as shown in below screenshot. As per the documentation, w...
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
