hi, i'm stuck starting usbh_hs2 from u-booti can already start usbh_hs1 at boot, in order to load kernel and fs from an usb mass storage. i wish to do the same with usb_hs2, is that possible? is one configuration from DTS or from U-boot source code? ...
Hello All,forgive me if this as an obvious mistake but I'm completely new to TouchGFX. I'm using STM32 MPU, with Cube, FreeRTOS and TouchGFXI have created a page in TouchGFX using the digital clock object, I have created a TickEvent to update the clo...
I have LCD COG with ST7586 Controller but my device must by drive this LCD by FMC ( backward compatibility ) How can I Drive this LCD from Linux ? I found driver stm32mp1-fmc2-nfc for using FMC by Micrel ETH but i'm not have any idea for use it for L...
Hello,I created a new project in STM32CubeIDE for my STM32MP157A by using STM32CubeMX. In it I enabled UART and FreeRTOS on CMSIS-RTOSv2 and that's all. I use the auto generated code.Then I wanted to use TraceAlyzer on top of FreeRTOS however, upon i...
I'm testing the Developer Package for STM32MP157c-dk2 demo board. Starter Pack is installed. When I compile the kernel as described in the Dev. Package's "README_HOW_TO.txt" file and update the kernel, The "Cube" example ceases running. It only says...
I want to enable input capture functionality on our stm32mp157c based system. I am using Timer 1 channel 4 for the same and have made the necessary additions in the device tree as follows: &dma1{ status = "okay"; /* USER CODE BEGIN dma1 */ s...
Hi everyone,I'm working on a custom STM32MP157 based board running custom Linux with Kernel v5.10.116. A LCD panel is connected using the LTDC display controller.I want to implement a splash-screen as soon as the power supply is on.I managed to add m...
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/stmicro/stmmacCan anyone tell is this driver for some specific ST(?) IP, or for a runaway collection of various Synopsys based IPs? Does the ethernet control...
We are trying to read an analog value from a sensor (PF14 pin - A0 on Arduino connectors) and send it over UART (UART7 - PE7 for RX, PE8 for TX) for reading in the terminal of computer. We use M4 for this aim. Our final goal is to read the analog val...
Next problem with my board is the RS485. I can send bytes, but can't receive because after sending once the DE stays always high. Without sending receive of course works.&uart5 { status = "okay"; pinctrl-names = "default", "sleep","idle"; pi...
