I am creating a custom yocto image on a STM32MP157F-DK2. I am using the meta-stm32mp layer as apart of the bitbake build. Yocto version : Scarthgap When I run bitbake I get this failure ERROR: hydra-image-1.0-r0 do_rootfs: Postinstall scriptlets of ...
Hello,We are using 5V/3A adapter to supply STM32MP135F-DK, and we are designing a mechanical structure for our project. To use the board without plug we have to use external power supply and do required connections (using gnd pins etc.). How can we d...
Hi,I'am also using STM32MP157C-DK2 to communicate between the A7 and the M4 using the Virtual Uart (OPENAMP and IPCC).I was trying to use STM32MXCube to configure the peripherals but the STM32MP157C-DK2 board is not available instead CubeMX has STM...
Hello everyone,We have a custom board based on stm32mp157c. We have a working bsp, which have tf-a 2.2 and u-boot 2020 version. Currently we are updating tf-a to 2.6 and u-boot to 2022. In our board we have burned mac address in the otp and we can re...
Hello @PatrickF ,Hope all is well.I need to access STGEN both in A7 core as well as M4 core. I have seen some previous posts related to STGENR register access.Credit to PatrickF for this code.#define STGENR_CNTCVL_OFF 0x0000 #define STGENR_CNTCVU_OFF...
Hello everyone, i'm starting a baremetal project on a MP135 and i'm facing a issue when I tried to configure ThreadX.I've already saw the issue in another post :https://community.st.com/t5/stm32-mpus-embedded-software/creat-a-simple-bare-metal-azurer...
Hello, I am developing a custom image using the layer meta-st-stm32mp in the mickledore branch, until that point, there are no problems.The problem is, since I want ti install the meta-st-x-linux-ai layer, I need to install meta-st-openstlinux first,...
Hi,I'm using STM32MP153C and I would like to communicate between the A7 and the M4 using the Virtual Uart (OPENAMP and IPCC).I'm using a custom distribution created using Yocto.When I initialize the virtual uart in the M4, /dev/ttyRPMSG0 is instantia...
Hello,Would it be possible to have an updated guide on how to use a custom device tree within my own layer for STM32MP1 Ecosystem 5.1.0?The one provided here "How to compile the device tree with the Distribution package" is clearly outdated, as the ...
