Member: 231728 Status: Offline Thanks Meter: 2,104 ![]() | UART1 gets initialized to some predetermined baudrate. Baud usually depends in chip input clock source. Observation has been made that UART1 is disabled on many phones, but can be enabled if proper firmware is used and eFuses are not ****n. |
