Hi,
I compile a small test piece (at bottom here) with command lines:
sdcc -mhc08 -c --stack-loc 0x00FF hello.c
sdcc -mhc08 --code-loc 0xE000 --data-loc 0x40 -o hello.S19 hello.rel
And appart from the non used main parameter warnings and
unreachable return the compile is clean.
And when it runs I get the following on my terminal
X = ?
and then the program presumably crashes as I get nothing further.
I presume a lot in my target/compiler setup is correct because
my own tiny printf is functioning. I also suspect that the
stdio/printf
is ok, woudl be hard to miss something this obvious. Instead
I suspect something is wrong with my compile options but
have not been able find out what.
Any suggestions?
Is 192 bytes of stack enough for the printf? I've seen implementations
that require 3 x max line lengt (250) bytes...

PTA=0x00;
DDRA=0x00;
x=0;
while (1) {
x++;
printf("X = %d\n",x);
}
return 0;
}
