Abstract
A method and system method for communication port management in a device. The method including enabling a set of communication ports in response to power up of the device, detecting connection at a port in the set of communication ports prior to operating system boot of the device, and connecting an external device to an operational component of the device in response to the connection at the port.
Claims17
A communication port manager comprising:
- a connection interface to configure connections between at least one communication port and a set of operational components, the set of operational components including a debug, diagnostic, or characterization controller;
- and
- an autonomous host detection (AHD) to detect a universal serial bus (USB) reset signal indicating a connection at the at least one communication port and to drive the connection interface to connect a host connected to the at least one communication port with at least one operational component from the set of operational components, wherein the AHD locks a connection between the at least one communication port and the at least one operation component at the connection interface in response to a successful establishment of a communication session between the at least one communication port and the at least one operational component.
A method for communication port management in a device, the method comprising:
- enabling, by an autonomous host detection (AHD), a set of communication ports in response to power up of the device;
- detecting, by the AHD, a universal serial bus (USB) reset signal indicating a connection at a port in the set of communication ports prior to operating system boot of the device;
- connecting, by the AHD, an external device to an operational component of the device in response to the connection at the port, the set of operational components including a debug, diagnostic, or characterization controller;
- and
- locking the connection between the external device and the operational component in response to establishment of a communication session.
2 more elements
A system comprising:
- a physical connector;
- and
- a system on a chip including a processing device, a memory device, an interconnect to communicatively couple the processing device and memory device, a connection interface to configure connections between a communication port tied to the physical connector and an operational component, where the operational component is a debug, diagnostic or characterization controller, and an autonomous host detection (AHD) to detect, a universal serial bus (USB) reset signal indicating a connection at the communication port and to signal the connection interface to establish a communication path between the physical connector and the operational component, wherein the AHD locks the connection between the at least one communication port and the at least one operation component at the connection interface in response to a successful establishment of a communication session between the at least one communication port and the at least one operational component.
