HelloI got a problem accessing a Rest point server.In what follows I will give you the verbose output on my STM32MP1 (Running under Buildroot)And the second one my Laptop (Ubuntu 18.04)I don't understand why is it working on one and not on the second...
Hi, I tried to follow the example in the youtube workshop, moving a pwm timer to the a7 side. I was able to create a dts file with cube mx but when running make to build the dtb i get"reference to non existent node or label "ethernet_mac_address""Is ...
Dear STM32 MPU Community,We are please to announce that New MP1 Ecosystem V2.1.0 is available. Please check out the Release note on STM32 Wiki to get complete description of content and new features. Please pay attention to the following : Ubuntu 20....
Hi,I need to supply external VREF for ADC which is assigned to M4 runtime context. Now when I start M4 firmware VREFBUF is activated (I'm measuring 2.5V on AVDD pin on DK2 kit). I suppose that I need to edit device tree, but I'm not sure. Can I for e...
when i using a 100M network cable in a gigabit network，It should be recognized as a 100M network under normal circumstances，But STM32MP1 is recognized as Gigabit，at this time the network is useless，led is light but not blink，I changing cable to a Gig...
Hello,My goal is to harden my Hardware security. I am using an STM32MP157C and buildroot as main distro.What exactly do I need to know when it comes to security? I am dealing with the hardware part and I am working on an IoT project.My colleague take...
Are there any specific kernel config options to get the console to work on UART4?I feel like I've tried every permutation of build, DT, and loading configuration at this point.I'm working on a custom board with a new 'machine' building on the Distrib...
I have a custom board I made with the STM32MP1 and I seemed to have royally messed up the clock circuit. I have an ASDMB-24.000MHZ-LC-T clock chip generating a square wave clock but HSE_OUT is being pulled high which puts the STM32MP1 into analog-byp...
