Hi,


Error 209053 ("Unexpected error in JTAG server — error code 35") is a JTAG server communication fault, and it typically surfaces together with Error (209040): "Can't access JTAG chain," which can be caused by a download cable problem, TDO not connected properly, a noisy TCK signal, or TDI shorted to GND.

Refer here: Error: “Can’t access JTAG chain”


I can give you the suggestion on the step-by-step troubleshooting as below:


  1. Check physical connectivity and board power first.
  2. Verify TCK signal integrity.
  3. Try a different USB-Blaster cable.
  4. Check for a JTAGServer service conflict.
  5. Check for the virtual JTAG device on the JTAG chain.
  6. Check for a JTAG Secure mode conflict (if applicable).
  7. Check cable driver installation.
