When a need raise up to use JTAG interface for system's devices programming or CPU debugging, usually the user layer application implements jtag protocol by bit-bang or using a proprietary connection to vendor hardware. This method can be slow and not generic. We propose to implement general JTAG interface and infrastructure to communicate with user layer application. In such way, we can have the standard JTAG interface core part and separation from specific HW implementation. This allow new capability to debug the CPU or program system's device via BMC without additional devices nor cost.
