1.2. Hitless Update using Internal JTAG Interface

Create an Intel® Quartus® Prime user design that enables internal JTAG interface by including JTAG WYSIWYG atom. All four JTAG signals (TCK, TDI, TMS, and TDO) in the JTAG WYSIWYG atom need to be routed out to ensure the internal JTAG interfaces of Intel® MAX® 10 devices function correctly. Prior to hitless update, user design must first program the CFM with application image through FPGA core fabric and drive all I/Os to the desired state. Reconfiguration is triggered using user logic with Dual Configuration Intel® FPGA IP.
