Hello,according to the STM32MP151A/D Datasheet (Table 13.) the voltage on VDD3V3_USBHS Pin can be 0 ... 3.6V when USBH not used.But on the another page of the Datasheet there is this section: "VDD3V3_USBHS and VDD3V3_USBFS are respectively the USB hi...
Hello, everyone!We are developing a custom board with the MYC-YA157C module. We took the the MyIR device tree configuration and add our layer there. The vendor config had a USB_OTG capable of supplying power and acting as a host. A separate chip, con...
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...
