Abstract
A method, a system, and a processor for loading a logical device online are disclosed. The method for loading a logical device online includes receiving an online loading command; disabling a Joint Test Action Group (JTAG) link of a board on which the logical device is located through a bus between a processor and the logical device according to the online loading command, and enabling a link between an input/output (I/O) interface and a JTAG interface of the logical device through the bus according to the online loading command; and controlling the logical device through the bus so that the logical device is loaded online through the link between the I/O interface and the JTAG interface of the logical device. In this way, the logical device is loaded online without occupying any I/O interface or requiring addition of any I/O device.
