Abstract
An eyewear device that includes a plurality of SoCs that share processing workload, and a USB port configured to perform low-power debugging and automation of the plurality of SoCs, such as using either a Universal Asynchronous Receiver-Transmitter (UART) or a Serial Wire Debug (SWD). The eyewear includes a USB hub configured such that the USB port can simultaneously communicate with the plurality of SoCs. The USB hub can be shut down to disable the USB hub, and all the SoCs can enter their low-power modes without being kept awake by a persistent USB connection. The eyewear includes a first switch and a control logic, wherein the control logic controls the first switch and enables the USB port to perform low-power debugging and automation of the SoCs. The eyewear further includes a second switch, wherein the control logic controls the second switch to enable the USB port to perform low-power debugging and automation of the SoCs via a processor, or to enable the USB port to control each of the SoCs.
