Hi, I'm trying to leverage the capability of lower words to be programmed once to one bit by bit to implement a sort of "forever growing counter", not sure if there is a proper naming for this.In the lower OTP zone, if I understood correctly, word 10...
I would like to clear up some confusion regarding the DSI VIO, the stm32mp157a datasheet mentions "1.2 V I/O for DSI interface" but in the EV1 kit the LCD used (the RK055AHD042-CT, for which it's impossible to find a datasheet for, could that be shar...
I just spent a day trying to configure a gpio with internal pullup using gpiolib. Could not get it configured. Then spent 2 days with device drivers and device trees, and got it working. Seems insane to me that configuring gpios should be this comple...
I have a customized STM32MP157AAD board with STPMIC1E PMIC.STPMIC1E is pre-programmed to have same NVM as 1A version.After power up, the board can download firmware by CubeMX and run uboot from SD card, even partially boot the linux kernel.However, t...
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...
