Document Type and Number:
WIPO Patent Application WO/2023/082184
Kind Code:
A1
Abstract:
A serial port switching apparatus and method, and a device, a storage medium, a system and a vehicle. The serial port switching apparatus includes three data selectors, wherein the data selectors can be controlled by means of one hotkey, such that an external interface is switched and communicated with among serial ports of a plurality of processors. In this way, operations such as debugging, maintenance and fault recovery of a multi-processor system can be realized by means of one external interface, and port resources of a single board can be effectively saved on, thereby solving maintenance and debugging problems when there is a shortage of ports on a single board in a multi-processor scenario.
