Hi,I have a small problem during stm32mp1xxx bring up. The Uart4 is debug console and is connected to stlink v2.1 on virtual serial. The problem is that this stlink makes all the time interrupt U-Boot and stack in it (stlink not connected to USB). To...
Hi,I am using an official STM32MP157C-DK2 board.I tested to build OP-TEE 3.17.0 for stm32mp1 however the boot hangs.I am building OP-TEE OS using:make PLATFORM=stm32mp1 \ CROSS_COMPILE_core=arm-linux-gnueabihf- \ CROSS_COMPILE_ta_arm64=arm-linux-gnue...
I’m new to the stm32mp1, I’m struggling to figure out how to get SDL2 working with OpenGL on the platform. I can create a window with SDL, but if I try to create an opengl window, I get a runtime error that GTX is not supported.I should note that my ...
I want to ensure I've used the most optimized code. I'm using gcc on linux. I have 4 values to store. If I use an array, I can for() loop as a convenience and shorter code, but is there added overhead compared to just using separate variables and hav...
Hi!I use buildroot - NOT openstlinux.My M4 code works fine in engineering mode, but fails in production mode.I suspect that it is due to the device tree file.The DTS file generated by STM32CubeIDE has some pinmux assignments to "RSVD", which fails in...
This is a problem that has bothered me for months.I hope someboby could give me some help.Firstly I use STM32Programmer to flash the STM32MP157F-DK2, it runs really fun.After I rebuild the kernel V3.1.0 followed by Wiki and use "scp arch/arm/boot/uIm...
I'm trying to figure out how to add OpenCV to my STM32MP157-DK2 Discovery Board. I am not new to ST Microcontrollers, but I am new to the MP1 and Cortex A processors. I'm also not new to Linux but am completely new to embedded Linux and Yocto.I can s...
For measuring the USB signal quality, it is necessary to print out test pattern on the USB interface. How this can be done on a customer board with STM32MP15x controller. Is a test software or source code available?
