Hi,I'm using STM32MP157A-DK1 and I built the image adding the logicanalyser layer (https://github.com/STMicroelectronics/meta-st-stm32mpu-app-logicanalyser).I follow the tutorial "How to exchange data buffers with the coprocessor".I add the rpmsg_hdr...
Hello,I am working stm32mp157c. I want to send the data coming from ipcc to m4 to another chip with spi.My code is;void MX_SPI4_Init(void) { hspi4.Instance = SPI4; hspi4.Init.Mode = SPI_MODE_MASTER; hspi4.Init.Direction = SPI_DIRECTION_2LINES...
Hello,I am working stm32mp157c. I'm trying to change the clock rate of stmcubeide using pll4q for spi45 (StmCubeIde outputs are attached.). Also The bsp setting is attached .Pll settigs is; st,pll@3 { reg = <3>; cfg = <1 32 5 66 5 PQR(0,1...
Hello!I'm using MYD-YA15XC-T board based on stm32mp151 kernel 5.4.And wanted to share files with it via FileZilla ftp/sftp file manager on the PC.But i could not connect to the board, there is always login incorrect error, whichever login or password...
Hi,We configured 1 uart for debugging purpose in our custom board at u boot level. Now we want to configure anthour uart for communicating with other devices.how do we configure second uart? For debug uart we use serial_putc() for transmit and serial...
I am using stm32MP157F-DK eval board (on windows) and I would like to try the DDR testing tool on cubeMX. But this is my first time trying to do so - I try to follow steps in "U-Boot SPL: DDR interactive mode" (url: https://wiki.st.com/stm32mpu/wiki/...
Hi,I'm using a STM32MP157a with yocto dunfell with 5.4 kernel version, and I'm trying to enable the kernel splashscreen. On my board I'm using the RBG lcd interface, and when the system is UP my application in showing curretly. On kernel config I hav...
Hi all,How can i add support for animated splash screen on stm32mp1 ?I have understanding of the psplash recipe used for custom bootscreen which works completely fine. I would like to have animation while system is booting up.Any inputs are highly ap...
Hi,Is there any chance to get a free documentation for the Vivante GPU on STM32MP157F?Want to support hardware accelerated 2D (not 3D) by the GPU on a bare-metal (own OS) project.I have found a reverse engineering project on GitHub facing this lack ...
