Yes, CONFIG_SYS_HZ is a frequency. And when you multiply a _frequency_, which is _ticks_ per _second_, by a number _seconds_ (in this case, 1/4 sec), you get a number of _ticks_. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
