hi ! I have run the simple Hello world program on the or1200 processor
following the Basic custom openrisc system HW/SW tutorial.
The hardware only contains the processor, debug unit,ram and the uart unit.
And I find a very strange phenomenon I do not konw why.
That is if I modify the hello.c code by making the 'char *str = "Hello
world!!!\n" ' inside the main funciton, the hello world program can not run
on the or1200 processor.
By modification,there is not a .data section. Thank you for your attention,
looking forward the answer.
the original codes:
*char *str = "Hello world!!!\n";*
int main (void)
{
char *s;
uart_init ();
for (s = str; *s; s++)
uart_putc (*s);
while (1)
uart_putc (uart_getc () + 1);
return 0;
}

uart_putc (uart_getc () + 1);
return 0;
}
