Reject SCO Agent not registered while running HFP profile using STM32MP257F-DK
I am using the STM32MP257F-DK with a WiFi-BT module. WiFi is connected via SDIO pins and Bluetooth is connected using UART6 pins through the 40-pin header.I am testing the HFP profile on the BT module. When I run the dial-number script from the ofono...
stm32mp257f-ev1 USB_DRD (CN15) configuration
Hello,I notice that on stm32mp257f-ev1 board the USB_DRD port (CN15) is active only if USBPD_DRPSI_CM33_NonSecure_stripped.elf firmware is running. I need to run a different firmware on M33 while using the USB_DRD port. Searching in board's DT I fou...
