STM32MP1 (engineering mode) - How to program the cortex m4 firmware from the command line?
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 ...

/dev/ttyRPMSG0: no such file or directory
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...
Resolved! Missing /dev/ttyRPMSG0
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: ...
Resolved! How to do python development targeting the STM32 MPU
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...
Error in debugging cortex M4 core in engineering mode of STM32MP157C-DK2 board.
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...
Resolved! STM32MP1 OTP word 10 and 11
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...
Resolved! STM32MP1 DSI voltage level
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...
On a linux stm32mp157 system can gpio with pullup or pull-down resistors be configured in user space ? If yes how?
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...
