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...
Does the stm32mp157 have an ESV or is there one in progress?
Hello everybody.On STM32MP2, is it possible to operate only the M33 like a microcontroller, without booting the A35? Also, if only the M33 is operated, can major peripherals such as I2C and Ethernet be controlled from the M33? (I assume that PCIe wou...
