Hello!I am trying to replicate the workshop STM32MP1 - 11 Inter-Processor Communication Lab Example. I create a new STM32 project and copy all the data from the lab example. Then I connect the device (STM32MP157C-DK2) in production mode to send messa...
Hi,After installing and running the latest, OpenStLinux discovered a problem with M4. Firmware is loading fine, but the system doesn't create /dev/ttyRPMSGx channel. What is changed in comparison to the dunfell?[ 2399.320707] remoteproc remoteproc0: ...
Hello,I have a STM32MP157F-DK2 and I'm planning to develop some python applications to run on the A7 processor. I have some questions related to python development for this platform, as I have not found too much documentations regarding this:Software...
I am using PlatformIO extension on Visual Studio Code and ZephyrRTOS framework to run blinky sample code for stm32mp157c-dk2 board in engineering mode. my use-case is to debug only in engineering mode with A7 core not being active or running.Debuggin...
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...
