Hello,I am working on evaluation board in that boot logs I am gettingNOTICE: Model: STMicroelectronics STM32MP257F-ev1 Evaluation BoardNOTICE: Board : MB1936 Var1.0 Rev.D-01What should I do to remove this "NOTICE: Board : MB1936 Var1.0 Rev.D-01" lin...
I'm running a build with meta-webkit on the scarthgap branch for the STM32MP257-EV1. I'm trying to get a web browser working for a custom web page and the performance is pretty poor and I'm not quite sure why. It seems like there's a lot of people do...
Hi, I'm pretty new to embedded development. I'm trying to set up a really basic 'Hello world' image for my M33 core on STM32MP257F-DK. My Linux A image has remoteproc set up, and rpmesgDmesg on linux host: [43834.220252] remoteproc remoteproc1: power...
STM32MP151 VDDCORE voltage if device above 600Mhz (800Mhz)1 VDDCORE voltage if device above 600Mhz (800Mhz). Custom Boardsee attachedThe data sheet states 2 VDDCORE voltages depending on the clock speed of part and i think yoiu can also set the clock...
Hi,we are developing a custom board based on the STM32MP157C. We would want to use several GPIOs for buttons. We have most of them working, but a couple GPIO pins do not yield input events to the Linux kernel.The problematic pins are PC1, PC2, and PH...
Can I install pyenv on my STM32MP257F-EV1 DK to manage python versions?I am currently running the starter package and have access to py 3.12.9I would like to run scripts with py v3.11.9At this stage I am not interested in updating the image - so plea...
I know, it's probably a design flaw, but hear me out.I'm designing a board with an STM32MP135 (in the form of a Myir Tech SoM). I have both USB1, and USB2 configured as USB-A / host mode. There is also an FTDI chip attached to UART4 for a console.The...
Hi,When transmitting data to the ttySTM0 port, the data goes to the UART4_TX pin connected to the JTAG virtual serial input. However, I need an available TTL serial port to communicate with a microcontroller. How do I enable the USART1 port connected...
Hello,I’m currently rebuilding the device tree (DTS) for our custom board. I’ve modified the pin configurations according to our schematic. Could you please confirm if updating only the following files is sufficient for our customization?stm32mp257f...
Does anyone know how to see and set the cacheable status of memory regions in an MP25x series micro? It is very simple for the H755: you pull up the cores in the Cube, and the MPU fields are all there to fill out. The memory regions outlined in the R...
