Hello,I'm stalling with an issue with Optee on a custom board with 256 MB of ram and an STM32MP135D.The environment was working with the DK (MP135F and 512M ram).I followed the guide for the configuration with 256 MB of ram (https://wiki.st.com/stm32...
Hello,There seems to be an issue with the I2C addresses listed in the MB1854 (B-CAMS-IMX) documentation and schematics (B01/B02).The documents show:IMU: 0xD4 / 0xD5ToF: 0x52However, these appear to be 8-bit addresses. The correct 7-bit I2C addresses ...
Section 2 of this page shows how to setup python for building firmware. It seems the rest of the tutorials assume you are building on a modern Ubuntu, so I would suggest changing the following lines:pip install pyelftoolspip install pycryptodomexto:...
On the STM32MP135F-DK, is the 4.3" LCD module physically removable? Or is CN16 accessible without removing the LCD?
Are there STM32CubeMX files for the example projects in STM32Cube_FW_MP2? It would really help understand peripheral configuration. Specifically the .ioc file for the OpenAMP example project used in this tutorial.I am trying to better understand ST...
