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?
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...
What's the process to add a native gcc to openstlinux-weston so I can compile from the command line on my DK2 dev board? I was able to rebuild using bitbake and started poking around to find which layer to enable to get a native gcc running on the ST...
I'm following the OpenAMP_TTY_echo example.To do a Tx it basically uses two functions: VIRT_UART_Init and VIRT_UART_TransmitAfter I use VIRT_UART_Init, I can see in the Linux terminal a log message something that suggests the initialization is workin...
Hi , iam trying to use spi1 pheripheral for the cortex M4 and iam using Pz0 as CLK, pz1as MISO, pz2 as MOSI, pz3 as NSS , but i tried several ways to do it by changing the kernel DTS and TF-A as well but no result , could anyone please help me how ca...
Hello. I am currently working on a custom stm32mp157a Linux based board with a KSZ9896 as network switch. At this point everything works on the board expect the RGMII connection to the switch. The RGMII is currently running in 100MBit mode for easier...
