Hi All,We bought 3 STM32MP157D-EV1 boards (https://www.st.com/en/evaluation-tools/stm32mp157f-ev1.html)While running in it as it is out of the box, we have found out that on-board STLink-V2.1 doesn't work at all when connected to Win11.We've installe...
Hello There,We are using the board stm32mp257-ev1. Which has "STPMIC25A".I want to change voltage of LDO2 and BUCK4 on boot permanently (NVM of stpmic25A).Can i change these supply from stm32mp257-ev1 board itself ? If yes, How ? Thanks and Regards,...
i am trying flash in SD card for STM32MP157F-DK2. I am getting the error as mentioned below Port configuration: parity = even, baudrate = 115200, data-bit = 8, stop-bit = 1.0, flow-control = off16:56:09 : Activating device: OK16:56:09 : Board : --16:...
On DK2, ADC is used to measure the voltage on cc lines, how to skipcan u give me the yocto steps to follow on commenting the following line in uBoot Device Tree:do u have to create a new layer or can we edit the patch file in the uboot device tree a...
Dear community,we use STM32MP1 SoC in some of our projects. Normally, we use eMMC card, so we use just two DIP switch positions: 000 (for uploading images into eMMC) and 010 (for booting from eMMC). We utilize SD card after booting from eMMC for st...
Hi, I have a custom board with a parallel RGB display connected to it that works OK when using pixman.If I enable the galcore.ko module, weston fails; [15:27:38.101] weston 10.0.0 https://wayland.freedesktop.org Bug reports to: https://gitlab.freede...
I will post this in the software-related section.
I'm running a small STM32-board with the original STLinux. This board comes with some kind of USB OTG port. Now I want to configure this port to let it act as serial device, means when I connect it to an other PC via that USB-port, I like to appear i...
Hi,We use the USB OTG controller in host mode with its internal FS PHY.Our DT node is the following:&i2c4 { ... pmic: stpmic@33 { compatible = "st,stpmic1"; ... regulators { compatible = "st,stpmic1-regulators"; ...
Hello, I need some advice.I would like to know if the STM32MP135 processor is capable of reading a USB UVC camera through its USB host port. I currently have a USB camera based on the OV9734 sensor.I know the documentation states that the processor s...
