Zynq UltraScale+ MPSoC ZCU102 Evaluation Kit - ARM 20-pin JTAG connector wires

Description

The Zynq UltraScale+ MPSoC ZCU102 Evaluation Kit header J6 is the ARM 20-pin JTAG connector. 

Reviewing this J6 header in the ZCU102 schematics, four wires exist that do not appear to have a purpose.

What is the purpose of the following wires on the J6 header: 

  • ARM_JTAG_TRST_B
  • ARM_JTAG_RTCK
  • ARM_JTAG_DBGRQ
  • ARM_JTAG_DBGACK

Solution


These four wires (ARM_JTAG_TRST_B, ARM_JTAG_RTCK, ARM_JTAG_DBGRQ, ARM_JTAG_DBGACK) are not connected to anything on the ZCU102 kit.

These pins serve no purpose on the J6 header and can be ignored.
