You will see LED D5, D6, D7 and D8 flash in a nice manner. In the same way you must be able to alter the hex leds. Freddy Spierenburg <freddy@xxxxxxxxxxxxxxx> http://freddy.snarl.nl/
Thanks. Works as advertised. A couples notes to anyone else interested - devmem2 does not use the au1000_gpio char driver so it could potentially be used with other processors. -busybox (if you are using it) doesn't support sub-second sleep like in the example given by Freddy.
