It is working in little endian mode. After changing the board's hardware from little endian to bit endian, the serial port print messed up. It prints now something like - "????????????????" on the screen. When I trace the execution, I can see the string the kernel is trying print is correct - "Linux version 2.6.31 ..." and etc. I guess it means the initialization of the serial port is not properly done. But I am not sure where I should check for the problem. The serial port device I am using is 8250. Please give me some advise.
