[U-Boot-Users] the problem on uart

[zhuzhenhua]

i write  my serial.c for our uart referring to cpu/mips/au1x00_serial.c
and it can output  the characters.
but if i output a string less than 8 byte, like "1234abcd", it works
well.and then if i change the
string to "1234 abcd", it will output "a234 abcd", does someone has
this situation on porting uart?

under the line is my serial_puts and serial_putc
-------------------------------------------------------------------------
void serial_putc (const char c)
{
	volatile u32 *uart0_stat = (volatile u32*)(UART0_ADDR + UART0_STAT);
	volatile u32 *uart0_txdata = (volatile u32*)(UART0_ADDR + UART0_TXDATA);

	if (c == '\n') serial_putc ('\r');

	/* Wait for fifo to shift out some bytes */
	while((*uart0_stat&UART0_STAT_TXFULL) == 1);
	*uart0_txdata = (u32)c;
}

void serial_puts (const char *s)
{
	while (*s)
	{
		serial_putc (*s++);
	}
}
