Subject: [U-Boot-Users] Problems with udelay() on AT91RM9200 !
Date: Mon, 22 Nov 2004 15:13:36 +0100	[thread overview]
Message-ID: <41A1F410.6040107@imc-berlin.de> (raw)

Hi there,

I just noticed that the implementation of udelay() - i.e udelay_masked() - 
resets the timer. Why is that?

This prevents me from doing something like

	start = get_timer(0);	/* get current time */
	do {
		if ( get_timer(start) > timeout) {
			puts(" TIMEOUT!");
			break;
		}
		putc('.');
		udelay(100000);
	} while (1);

:-(
