Hello, I am trying to establish an interprocessor communication between the cores A7 and M4 with the with the Stm32MP157. The example from ST "OpenAMP_TTY_echo" works fine, but as soon as I change the received buffer or try to send a costomize buffer...
I am trying to use the USB OTG in host mode, but it kept giving me the famous HANG! Soft Reset timeout GRSTCTL_CSFTRST error.According to the datasheet, when we set the register, it should reset the core but also clear itself but the following condi...
I'm getting these errors on the consoles when FSBL (TF-A) is trying to download SSBL (U-Boot). What could this DFU error be? I've added the following to the U-Boot DTSI file so it ignore USB OTG VBUS and USB OTG ID. I've tried this using Linux and Wi...
Hi,I am wondering if it is possible to internally connect two GPIO pins by software, not using wires.Thank you
Hi!I am using STM32MP157C-DK2 board to create an application on the screen (using GTK library). My idea is to start coprocessor firmware from the A7 application with the following commands (system commands):int main (int argc, char **argv) { GtkApp...
I've been validating my DDR interface with DDRUTIL through the CubeMX DDR Interactive which seems to pass the tests. When I boot TF-A it is failing both address bus testing for 1's and 0's. But I can run this same test through DDRUTIL and it passes. ...

We're are trying to use BKPSRAM in application code insecurely. According to the stm32mpu BKPSRAM_internal_memory page, we need to "set BKPSRAM as non-secure and degrade low power modes support, removing Standby mode"Apart from setting the etzpc peri...
Is it possible to run touchgfx on the STM32MP1? TouchGfx can be run on the STM32F4 with the M4 core. Is this also possible on the M4 core of the MP1? Is there any support from ST or has anyone already implemented this?
Hello,Upgrading Linux 5.4 causes SPI to fail to initiate (see boot log snippet below). Any ideas what would cause this (same DT)?Again thanks for your great support!Best RegardsChrister[ 2.782226] spi_stm32 4000c000.spi: failed to request tx dma ch...
