I have catered this issue as below: Doesn't the OSCR increment as: 0xfffffffe 0xffffffff 0x00000000 0x00000001 0x00000002 0x00000003 0x00000004 0x00000005 I'll let you count the number of ticks there, but I think you'll find it's 7 not 6. ------------------------------------------------------------------- List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php
