Hi everyone,I am working on an STM32MP2 platform and facing a persistent issue with LPUART1 in interrupt mode.SetupMCU: STM32MP2UART used: LPUART1 (RS485 communication via MAX485)Debug UART: UART5 (polling mode, printf works fine)Using:HAL_UARTEx_Re...
Hello,I don't have so much experience with the boards of STM32 and I'm struggling a bit (actually a lot) with a quite simple task.I want to run a blinking test with the board STM32MP257F-EV1.I installed the STM32CubeMX, STM32CubeIDE and STM32CubeProg...
Hi,I'm working on to get the multiple SAI to Codec to work synchronized as the connection below,1x MCLK1x BCLK1x FSYNC4x DIN4x DOUTWhere the three Clocks 1x lines (MCLK, BCLK & LRCLK) from one SAI master (actual pinout clock) & other SAI (pinout DIN ...
Hi everyone,I'm currently validating a custom board featuring the STM32MP257 interfacing a single 16-bit DDR4 at 2133MT/s (Point-to-Point topology). I am using the ST-provided Excel tool ("Examples of DDR memory routing on STM32MP2 MPUs") to extract ...
Hi,I'm designing a board with STM32MP153FAD and have a question about DDR layout reference.Which reference should I follow for the DRAM section?Eval kit MB1272C_03 layoutST's published reference DDR layout.Questions:Which is the recommended reference...
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...
