Description

technical field [0001] The invention relates to the technical field of network equipment, in particular to a USB-to-SMI method, device, converter and storage medium. Background technique [0002] Currently, the CPU or the MAC accesses and controls and manages physical layer devices or other network devices through the SMI. Usually embedded CPUs have this bus, but general-purpose CPUs (such as X86 CPUs) do not have this function. As a result, under the CPU device, if you want to access the network device connected to the bus, you must use existing hardware resources to simulate. Usually, GPIO is used to simulate the SMI bus, and its cost is relatively low. If there are enough GPIO supports on the hardware, it can be implemented relatively easily. But the usability is poor, because GPIO uses a specific PIN pin, if the CPU uses this GPIO as a conversion SMI interface, all modules that are compatible with it must be connected using this pin, which is less flexible.
