This error means You have soldered some Jtag wires incorrectly or You have short circuits. Please carefully check soldering of all Jtag wires.

TDO is constant high error means your jtag connection problem, use magnetic wire less than 3inch clean the jtag pinout do it again make sure other wire not short to other wires

check out again and

is solder problem

or do not connect reset wire

or check your rj45 cable

As I have said above, this error means You have soldered some Jtag wires incorrectly or You have short circuits on PCB. Please carefully check soldering of all Jtag wires.
