![]() The number of hwspinlocks are determined based on the value read from the IP block's SYSSTATUS register. However, the module may not be enabled and clocked, and the read may result in a bus error. This particular issue is seen rather easily on AM33XX, since the module wakeup is software controlled, and it is disabled out of reset. Make sure the module is enabled and clocked before reading the SYSSTATUS register.
