The board was designed incorrectly, they have pins for a JTAG but forgot to actually route them to the MPU. The eMMC is not going to have a first-stage bootloader on it, and it's looking like it's not possible to flash an SPL to the eMMC over USB al...
Hi I was trying to connect a custom LVDS display to my STM32MP257F-dk board but it does not seem to work, The display has a resolution of 1024x600 pixel and also it uses "vesa-24" scheme, so i assume that i don't need to change the device tree as it ...
It seems Azure® RTOS might be able to run on STM32MP135AAE3, the "Introduction to Azure RTOS with STM32" says "All STM32MP13x lines are covered by default by Azure® RTOS middleware within the matching STM32Cube MPU packages" but I'm having trouble fi...
I've inherited a custom board that contains (among other things) an STM32MP135AAE3, an eMMC, and an Ethernet controller (DP83826ERHBR). No SD card, no HDMI, no keyboard. For that matter, no JTAG (board error). I had thought about running Zephyr but...

Hi,I am new at STM32MP2. I have a stm32mp25f-ev1 board and I was able to build the distribution package and to run it on the board.My next step is to build an image for my own board that was designed using the eval board as a reference, but with many...
I'm using a custom board, and use the optee device tree generated by STM32CUBEMX and full UART log. Panic at core/kernel/dt_driver.c:904 <probe_dt_drivers>. How to solve this problem?
Hello ST Community, We are developing a product based on STM32MP151 which has 2 (WKUP) GPIOs connected to wake our battery-powered product from sleep or shutdown. Can somebody please let us know how we can detect which GPIO triggered the wakeup in li...
Hello,We have designed a custom board based on the STM32MP157F-DK2 platform.The design uses the STM32MP157FAC MPU and includes the following peripherals:MicroSD (SDMMC)STPMIC1 PMICDDR3L memoryEthernetUART4 for console My power sequencing, PMIC wiring...
I'm facing a problem when trying to build an image for my mp257f-eval board using a custom device tree generated from cubemx. I've followed the instructions from the following wiki : https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_wi...
