Hi,I am working on the implementation of a AI algorithm in a heat pump. My first choice was the SPEAr320 MPU: it is outdated though, it doesn't have enough resources and any FPU. Which MPU should I choose for this application ? that is to say inferen...
I recently purchased a STM32MP135F-DK Board to develop a IoT application. I'm slowly learning my way though OpenSTLinux. but for a urgent need i need to develop a hand application demo. the product description says it also supports bare metal RTOS ...
Hi, I'm working with the STM32MP157 and I'm trying to interface it with 4 lanes DSI display. the problem is that the STM32MP157 support only DSI with 2 lanes. In the other hand, I can't program the controller of the display (JD9365DA-H3) to switch wi...
Hello,I want to send in reliable way messages from M4 core to A7 core (in my case its the HW is STM32MP157 -DK2 ). The problem is that when A7 core is busy, the messages are truncated.The quesiton is how M4 core would know that A7's buffers are full?...
Hello,I want to upgrade my hardware to new openstlinux kirkstone release november 2022.First test on eval board was successful.I have written custom device tree files and compiling for tf-a, u-boot, fip and kernel is fine.However when I try to flash ...
