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...
