Abstract
Examples of techniques for hang detection and recovery are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method may include: sending, by a processor, a read request to a controller; detecting, by a data hang detection circuit, the read request; initiating, by the data hang detection circuit, a counter when the read request is first detected; monitoring, by the data hang detection circuit, to receive a read response from the controller; and responsive to the counter reaching a timeout threshold before receiving the read response, sending, by the data hang detection circuit a timeout error to the processor via a multiplexer in the data hang detection circuit.
