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?
Hi, I installed node.js with apt-get on my STM32MP157C-DK2, which worked great.Now I want to install another package but it failsapt-get install nodejs-npm... Need to get 7286 kB of archives. After this operation, 0 B of additional disk space will be...
