Are there any specific kernel config options to get the console to work on UART4?I feel like I've tried every permutation of build, DT, and loading configuration at this point.I'm working on a custom board with a new 'machine' building on the Distrib...
I have a custom board I made with the STM32MP1 and I seemed to have royally messed up the clock circuit. I have an ASDMB-24.000MHZ-LC-T clock chip generating a square wave clock but HSE_OUT is being pulled high which puts the STM32MP1 into analog-byp...
Hi AllWhen building "Eco system V2.1.0" distribution of Custom Board based on STM32MP151C chip, there is a problem that devicetree symbolic link is not created.Symbolic link of custom board devicetree is not created in "tmp-glibc/work-shared/stm32mp1...
Hi, I am currently looking at how to enable a GPIO pin on the M4 with the MP157A-DK1 kit. In the datasheet it is unclear to me how I can assign the gpio pin specifically to one of the two processors (A7 or M4) or is this not necessary?Thanks, Rens
Helloi'm trying to get started with the STM32MP1 env, and I'm having some issues building the trusted firmware boot image, after following the steps from: https://wiki.st.com/stm32mpu/wiki/STM32MP15_TF-AI'm, building it with the following commands, o...
I am installing all of the prerequisites and have some issues. This is on Windows 10 running VirtualBox with a Linux environment running Ubuntu 20.04.1 LTS. Everything seems relatively smooth but some of the apt-get commands don't seem to work, speci...

Is it possible to boot over UART on the STM32MP157C-DK2? I set the BOOT pins as following:BOOT0 - OFFBOOT1 - OFFI am using the FT232 UART-USB Adapter and have connected the following pins:UART GND - CN16 GNDUART VCC - CN16 3.3VUART TX - CN14 ARD_D1UA...
Hello,No dev kit is available for STM32MP151x microprocessors, do you know if it is possible to replace the STM32MP157 chip by a STM32MP151 one on the STM32MP157A-DK1 ?I have read that STM32MP1 are pin to pin compatible, but I want to be sure and if ...
