Hi All,
I'm trying to activate a serial console on my embedded system , i'm
using drivers/arch/serial.c (standard 16550 serial) to activate a serial
console.
When booting the kernel, only the printk's appear on the console but the
printf's that are run from the applications don't appear (interrupt
driven driver).
When I define
#define SERIAL_DEBUG_RS_WAIT_UNTIL_SENT
the driver works fine (ofcourse with some debug messages).
The odd thing is that the #define only enables some printk's without
doing anything else to the hardware or the software. So why after
#defining it the driver works fine ?
If any one has encountered this problem before, or if you have any link
that can help me please message me to my e-mail directly.
p.s. I'm running kernel 2.2.12
Regards,
Rabeeh
