Regarding the bogus numbers occasionally printed, you can see that the
leading
ffs are printed when the character has its bit7 set to 1. This occurs
because in
printf("%02x ", s[i]);
the expected argument for %02x is an integer, and since the actual
argument is
a (signed) character, the compiler promotes it to an integer extending
the sign bit.
You can simply write instead
printf("%02x ", (unsigned char)s[i]);
and the problem should disappear, since in this case the promotion to
an integer
adds non-significative 0s that are ignored when printig

Ogg: [Qemu-devel] Printing bogus values in ne2000_asic_ioport_read()/
ne2000_receive()

Hi,
I am using QEMU in one of my research projects. I
landed in a problem where I see bogus numbers being
printed when I printed the packet/each word that is
received from ne2000.

In ne2000_receive(), I copied the packet received to a
static char [] and printed the packet using
static void print_packet(char *s, int len)
{
int i,j;
for (i=0;i
if (i%20 == 0)
printf("\n");
printf("%02x ", s[i]);
}
printf("\n");
}
And some bytes it prints as fffffffff
instead of just the last byte.
For eg:
52 54 00 12 34 56 00 ffffffff 4f 0a 46 05 08 00 45 00
00 ffffff80 00 00
40 00 40 01 ffffffbc 2b ffffffc0 ffffffa8 fffffffe
fffffffe ffffffc0 ffffffa8 ff
