Abstract
A method for resetting at least one processing device in a power-over-data linear bus interconnecting a plurality of processing devices, the method including, at a first processing device of said plurality of processing devices: sending a protocol data unit comprising a prior-reset notification to all other processing devices of the plurality of processing devices, and sending a physical reset signal to all other processing devices of the plurality of processing devices, wherein the prior-reset notification is configured to prevent a processing device that receives the physical reset signal from resetting, if the protocol data unit comprising the prior-reset notification has been previously processed by the processing device.
Claims17
A method for resetting at least one processing device in a power-over-data linear bus interconnecting a plurality of processing devices, the method comprising, at a first processing device of said plurality of processing devices:
- sending a protocol data unit comprising a prior-reset notification to all other processing devices of the plurality of processing devices, and
- sending a physical reset signal to all other processing devices of the plurality of processing devices,
- wherein the prior-reset notification is configured to prevent a processing device that receives the physical reset signal from resetting, if the protocol data unit comprising the prior-reset notification has been previously processed by the processing device.
A system comprising a plurality of processing devices interconnected by a power-over-data linear bus, wherein a first processing device of said plurality of processing devices comprises:
- means for sending a protocol data unit comprising a prior-reset notification to all other processing devices of the plurality of processing devices, and
- means for sending a physical reset signal to all other processing devices of the plurality of processing devices,
- wherein the prior-reset notification is configured to prevent a processing device that receives the physical reset signal from resetting, if the protocol data unit comprising the prior-reset notification has been previously processed by the processing device.
