Hi ST Community,I'm trying to build my linux image for STM32MP157F-EV1 board with the following commands.Linux Commands:PC $>cd <working directory path>/Distribution-PackagePC $>mkdir openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15PC $> cd openstlinux...
The default configuration for the trusted defconfig has CONFIG_ENV_IS_NOWHERE=y . How can I store the u-boot-env on mmc such that fw_printenv can read it. When I took out CONFIG_ENV_IS_NOWHERE I am unable to get the boot process to u-boot. The last t...
I am having difficulties using built-in ST-Link debugger on STM32MP157D-DK1 Discovery Kit. I am using the latest version of the STM32CubeIDE, Version: 1.10.1. Upon connecting the debugger it asked for FW upgrade on the ST-Link which I accepted and it...
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 ...
