Hi!STM32MP1 provides a real-time core, and we use it for the hard-real time. But additionally, we would need the application running on the two fast cores to also be real-time. (with softer constraints but still better than standard scheduling on Lin...

Hello,I'm currently using the following setting for the ethernet0 in Linux 5.7.6:ðernet0 { status = "okay"; interrupts-extended = <&intc GIC_SPI 61 IRQ_TYPE_LEVEL_HIGH>, <&intc GIC_SPI 62 IRQ_TYPE_L...
I build the OpenStLinux from the ST Yocto project and added the Preempt_RT patch to make the kernel "real-time". ( uname -a correctly report PREEMP_RT kernel).After this, I am checking real-time capabilities with the rt-tests utilities.When calling r...
There seems to be an option to change assignment in STM32CubeIDE (in .ioc file), but DMA1 is assigned to A7 and DMA2 is assigned to M4 and the another core is always greyed out. Is it possible to unlock those settings?
What possible displays mentioned below are suggested to integrate with stm32mpu boards for production purpose with doing less configurations?The touchscreen will show linux gui app.1. LVds with capacitive touch2. Rgb paralell dispaly with resisitive ...
Hello,I am using the STM32MP157F-DK2 and recently went through a textbook rebuild of the Linux kernel, the modules and the gcnano driver (for GL support). All is well and yet, I see only one of the two CPUS. dmesg tells me the following:[ 0.000000]...
Hi,I'm looking for a processor for a camera application that have the following features:MIPI CSI2 interfaceץBT5 connectivity abilities. Small as possible.Application processor like the Cortex A53. Thanks,Avishay.
