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) but the /dev/ttyRPMSG0 does not ...
We quite recently learnt of the move from U-Boot SPL to STM32DDRFW-UTIL and that the MX too would not longer work with the former. That wasted a decent amount of time.The problem is although the code for STM32DDRFW-UTIL is available our PMIC is on I2...
In engineering mode (BOOT0:off, BOOT2:On) I want to update my cortex-m4 firmware from CMD, not an IDE. What is the command to do so?Thank you!Note: I tried using the STM32_Programmer_CLI executable but it keeps seeing the a7 only, I cant communicate ...

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...
