Hi, I am working with the STM32MP25 and trying to use the I2C peripheral from the Cortex-M33 coprocessor.The STM32MP25 includes an Arm Cortex-A35 core running Linux and a Cortex-M33 core for real-time applications. I am able to successfully load and ...
Following the tutorial here, at step 8, I get to the part where you load firmware onto the dev kit, but I always get an error "No ST-Link detected". As far as I am aware, programming should be done over the USB cable, or UART, not ST-Link?The board ...
Hello ST team.I am working on the boot chain from qspi NAND flash memory. The board is based on the STM32MP135F SOC and the w25n01gvzeig winbond 128MB IC. The IC is sitting on qspi bank 1 on the default BOOTROM pins (AN5474 p49).I have already succee...
I'm planning to use ImGui as framework for creating a GUI application on the MP257 processor.The ImGui is bloat-free e.g it only uses the GPU hardware (OpenGL, Vulkan, etc...) to visulize the graphics such as buttons, menu, labels etc.Will an applica...
I am working on a custom board with STM32MP133A cpu and Kingston EMMC08G-ML36 EMMC. The board boots fine from the EMMC, however if the board resets due to kernel panic and/or watchdog timeout it fails to boot from EMMC and enters DFU mode (where it h...
Hello,I’m working with an STM32MP255 and want to access GPIOs from the Cortex-M33 coprocessor (not from the A-core/Linux side). I’m trying to understand the correct workflow and configuration steps so M33 firmware can drive/read GPIO pins. Specifical...
Due to the high cost of RAM. I wonder if ST have plans or other information about which 4GB RAM vendors fits MP25x products?I know that ST have information about other RAM vendors on their wiki. Only one 4GB vendor is mention there.I bought the 4GB R...
Hi everyone,I am encountering an issue while trying to flash OpenSTDroid onto my STM32MP257F-DK board.I downloaded the Starter Package from the official website and used STM32CubeProgrammer for the installation. However, the flashing process consiste...

In my custom FSBL on an STM32MP135AAE3, everything runs great except anytime I try to modify one of the GIC flags it pretty much ignores me completely (when I read it back, my changed bits aren't changed). I'm guessing this is some kind of trust zon...
