Hi The terminal printing information is as follows. This TF-A will start properly in EMMC. In the docs/plat/stm32mp1.rst file, I saw that USB is not supported. May I ask how to modify it so that it can be burned via USB Regards User.44
Hi All.I am currently using STM32MP15-Ecosystem-v1.2.0. for DK2. At the moment I don't plan to completely upgrade to v2.0.0 but I would like to test the new kernel version (5.4.31). I have compiled the new kernel version and a new device tree but onc...
Hi: I'm testing the host mode.I follow the wiki steps to configure hostspot:https://wiki.st.com/stm32mpu/wiki/How_to_configure_a_wlan_interface_on_hotspot_mode.This was giving me the following out-put . I couldn't find what makesthis problem. I am...
hi i am using stm32mp157caa3, there is a i2c slave operating at 3v3, while design, we have not connected( "forget")pull up line on i2c clk and data line, so i tried enabling open-drain internal pull up in dtsi , but i2cdetect is not able to find the ...
I have a problem with running the software on the Cortex-M4. Probably the default device tree configuration does not start the m4 core. Has anyone used a SoMlabs board and tried to run software on the Cortex-M4 core?
Hi, i moved to new ecosystem v2.0 "dunfell" and added my layers of wifi,camera, openCV and python packages from old Yocto ecosystem. when i trying to burn my custom board eMMC with my dcmi camera plugged it stuck on U-boot waiting for the USB connect...
Hi,I am using MB1166 Rev.A display with STM32MP1 board. In the default mode it shows the logs in portrait mode, how can I rotate it to landscape mode?Regards,Shrikant
Hi,I'm lead embedded engineer at some company. Our current tech stack is android board for GUI and networking connected to stm32f2 over uart, which controls our hardware.We're trying to give a shot to stm32mp1, which could be great way to reduce hard...
Hi,Please tell me whether the virtual Uart take any hardware resoure (eg: actual UART port, PIN).Does the virtual Uart support the baudrate change? If it support, what maximum speed it can support?The virtual UART demo example in "STM32Cube_FW_MP1_V1...
Hi all, I am trying to upgrade the kernel on a board running STM32MP15 BSP v1.2.0. From what I have seen, the kernel from BSP 2.0.0 is not compatible with the tf-a and u-boot used in previous BSP versions; I assume that this is due to a change in the...
