I have a new STM32MP157C-DK2, it stops (hangs) very often.Especially when I run a demo.The 3D GPU demo runs no longer than 30 seconds.The Video playback doesn't finish mostly and then the system crashes again.Is this a known problem. Are there update...
I'm currently working with the Seed STM32MP1 SoM which has STPMIC1 attached to I2C2. I've been working on setting up a device tree for it, but I've been hitting some bugs. When booting the mainline ATF with my device tree (modified DK2 board, just wi...
Hi,I'm trying to have some accurate perf measurements with the STM32MP1 for my program on Linux. I've tried several things, among them to use perf Linux tool.The number of cycles does not match the time elapsed, i.e. the freq processor is at 650Mhz a...
Hello dear.I try change touch driver so i try refer "https://wiki.st.com/stm32mpu/wiki/Touchscreens_hardware_components" page.But The page said "permission error".What can i do solve it?Thank you.
Hello,i'm currently trying to attach a TI DP83848CVV phy to the STM32MP157. We have an external 50MHZ clock which is supplied to the PHY and PA1 (ETH1_REF_CLK).These are the pinctrl values (generated by CubeMX):ethernet0_rmii_pins: rmii-0 { pins1 {...
I'm trying to connect to my DK2 from STM32CubeIDE but the ST LInk port doesn't seem to work. In Device Manager I see "Unknown USB Device (Device Descriptor Request Failed)". I tried several cables and ports on my PC.I should mention that I'm running ...
Greetings everyoneThere is a wiki article (closed to the public) about enabling Jailhouse on STM32MP1x that lead me to believe that the STM32MP15x 's Dual Cortex-A7 cores implement the Virtualization Extensions.To my understanding, the reference manu...
