Hello, I'm porting Denx linux 2.4.4 to my company MPC8260 board. The board doesn't have the real UART to be configured as ttyS0. It has a virtual UART (a memory location where characters are read/written from/to. Another processor will take care of UART translation.)
I haved modified uart.c to provide basic serial i/o functions using the virtual uart. When running with NFS root filesystem, I got this: ---------------------------Message------------------------------------------ modprobe: modprobe: Can't locate module char-major-4 INIT: version 2.78 booting Welcome to DENX Embedded Linux Environment Press 'I' to enter interactive startup.
