ID:260009 Unexpected JTAG communication error

CAUSE: You tried to download a design in the In-System Sources and Probes Editor. However, the In-System Sources and Probes Editor cannot communicate with the JTAG chain. This message can occur because the board is not powered on, the programming hardware is not connected, there is a problem with the circuit board, or you did not SRAM Object File (.sof).

ACTION: Make sure the circuit board is powered on, the programming hardware is connected properly, and download the current SOF.
