Why does Etherlink print “Failed to recv H2T header” when using the JTAG-Over-Protocol FPGA IP

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 24.1 and earlier, you may see the Etherlink tool print “Failed to recv H2T header” when using JTAG-Over-Protocol FPGA IP on Agilex™ 7 FPGA and SoC FPGA.

Resolution

To avoid this error, enable the Enable use of TCK-ENA option in the JTAG-Over-Protocol FPGA IP.

The problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition Software.
