Hi, Dhanasekar, Linux boot parameters allow specifying serial baudrate. An example would be: earlycon=uart8250,mmio32,0xXXXXXXXX,115200n81 console=ttyS2,115200
Please make sure the serial device info (including MMIO or I/O address and the device name) matches your platform in above settings. I guess character set is not an issue here since Linux only outputs basic ASCII codes.
