Hi again,

seems that there is a problem with gd - at least your test breaks...

I added unsigned long temp at the end of gd.

And added
unsigned long a=0;
a=gd->temp;
gd->temp = 4;

to calc_divisor

Here is a part of the debugging session:
Breakpoint 1, calc_divisor (port=<optimized out>) at serial.c:171
171             a = gd->temp;
(gdb) p/x a
$1 = 0x0
(gdb) s
^C
Program received signal SIGINT, Interrupt.
0x00014010 in ?? ()

had to use Strg+C to get back a gdb prompt.

But if do: p *gd
The output seems to be ok (for this stage of the SPL):
$3 = {bd = 0x40203df0, flags = 1, baudrate = 115200, have_console = 0,
env_addr = 0, env_valid = 0, fb_base = 0, timer_rate_hz = 0, tbl = 0,
tbu = 0, timer_reset_value = 0, lastinc = 0, relocaddr = 0, ram_size =
0, mon_len = 0, irq_sp = 0, start_addr_sp = 0, reloc_off = 0, tlb_addr
= 0, jt = 0x0, env_buf = '\000' <repeats 31 times>, temp = 0}

Ideas? A Problem with the linker script maybe?

Regards
Simon
