Hi,I flashed OS "en.FLASH-stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12.tar.xz" to board STM32MP157C-DK2. Then remove all the cable,and only remain a type C cable connected with my laptop Type C port.But the kit can't power on.Could you tell me how t...
I created an eglfs Yocto build that can run the simple Qt5 demos, but I'm seeing fairly high CPU usage and I'm trying to figure out if the GPU is being used. I pondered that the GPU may not accelerate 2D graphics very well and does better with actual...
Hi, i have a question regarding to exit the Low Power Mode on CM4. Is it possible that i can exit the CStop or CStandby Mode via an Rx Messages of the CAN Bus, when the CAN Bus is assigned to the M4. Iam confused because almost every Bus is listed in...
Hello,I am using stm32mp157c-dk2 board and working on "How to exchange large data buffers with the coprocessor - example" from the wiki:https://wiki.st.com/stm32mpu/wiki/How_to_exchange_large_data_buffers_with_the_coprocessor_-_exampleI need to do so...
Hi,i just implemented the OpenAMP_tty_echo example for my device. And i just wanna know if i have the right understanding for it. Iam using two virtualUARTS, does this mean that i have two Endpoints over one RPMSG Channel. Or do i have two RPMSG Chan...
I think I have encountered some difficult problems. I hope the engineer of ST can help me.I configured SPI+DMA to CM4 and then created two rPMSGs. RPMSg0 transmitted the data to CA7 in real time and RPMSg1 transmitted the heartbeat signal.When CA7 re...
