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...
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,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...
Hello,we have product based on a STM32MP157 running Linux. The distribution is based on Yocto kirkstone and we are using a 6.1.82 Kernel. For the MP1s' GPU we use the open source entaviv driver that ships with this kernel. The device has a graphical ...
I'm trying to get a Raspberry Pi DSI display working with a custom board using a STM32MP157F.From the wiki I have the following.&dsi { status = "okay"; ports { port@0 { reg = <0>; dsi_in: endpoint { remote-endpoint = <<dc_ep0_out>; ...
Hey,,I'm working on an STM32MP2 project and need help with Yocto. I generated a device tree with CubeMX and want to modify it so that I can activate the ums 0 mmc 1 command in the U-Boot terminal with the USB configured for 3.x speeds instead of the ...
Hello ST Community,I am working with the STM32MP257F-EV1 Evaluation Board and following the steps described in the official STM32 DDR Firmware Util documentation as per attached document below.While performing the DDR firmware update and running the ...
