Subject: [U-Boot]  Problems with NetConsole II
Date: Thu, 8 Oct 2009 00:41:05 -0700 (PDT)	[thread overview]
Message-ID: <25799667.post@talk.nabble.com> (raw)


Hi,
I'm trying to run NetConsole, listen for incoming messages for 1 sec, and
continue according to the message type.
On the other side (PC) i'm sending a broadcast message on port 6666 every
250 ms.
What i see is a very unstable behaviour
Sometimes i get nothing, sometime only part of the message, and sometimes it
fails to continue..
I also tried to listen for 5 sec, and it looks a little better, but still
unstable behaviour

The code i use is:
setenv("stdin", "nc");
printk("waiting for network message...\n");
		
timeStart = get_timer(0);
while(1)
{
	c = getc();
	if(c != 0)
	{
		printk("%c", c);
		buffer[index++] = c;
	}
	if(index > 127)
		break;
	if((get_timer(0) - timeStart) > 5000)
		break;
}

Thanks,
Alex
