Abstract
Systems, methods, and circuitries are disclosed for providing security for tool access in a device. In one example, a device includes a bus master, a memory protection unit, and protection agent circuitry. The bus master is configured to store, in a first range of memory locations, request messages received from a tool interface of the device, each request message encapsulating a tool-related command. The memory protection unit is configured to prevent the bus master from accessing memory locations outside of the first range of memory locations. The protection agent circuitry is configured to access the first range of memory locations to identify one or more request messages, and send each respective request message to one of a plurality of component circuitries based on a component circuitry identified by the request message.
