serial console output problem


hi,
I have a problem when i port ecos to my S3C4510B platform.I use the SNDS default template.When I run the "hello.c",it can run normally,the console device is "/dev/ttydiag".


But when I use the "/dev/tty0" as console device, the hello.c cannt run.The console ouput is "$T050f:0200ffe3;0d:f0320500;#b3".I use the ymodem load the execable file.

What is this? How solve it?
--------------------------------------------------------------------------------

I use the GUI configtool to modify this:
In "Serial device drivers",
	"Console device name" is "dev/tty0"
	"TTY mode channel #0" is enable
	"TTY mode channel #1" is enable
	"TTY mode channel #2" is enable
	"Hardware serial device drivers" is enable
In "ISO C library",the "Default console device" is "/dev/tty0"
----------------------------------------------------------------------------------

The ram.ldi file is:

MEMORY
{
ram : ORIGIN = 0x000000, LENGTH = 0x01000000
rom : ORIGIN = 0x1000000, LENGTH = 0x200000
}
SECTIONS
{
SECTIONS_BEGIN
SECTION_fixed_vectors (ram, 0x200, LMA_EQ_VMA)
SECTION_rom_vectors (ram, 0x00040000, LMA_EQ_VMA) SECTION_text (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fini (ram, ALIGN (0x4), LMA_EQ_VMA)

}
