You're right. Seems to be an exception, though: According to ctags there are 40 separate implementations of udelay(), and the ones in lib_ppc and lib_nios seem to be the only ones that actually do call WATCHDOG_RESET. > Which platform are you using?

Unfortunately there's no central udelay() implementation in lib_arm.
