    • Error: “Unable to enable OnCE 10-bit TAP controller Failed to connect.”

      Hello.
      I use Programmer firmware: J-Link V11.
      Program SEGGER J-Link Registration V8.10.
      MCU SPC560B50L5 in LQFP144 case on the board, connection via JTAG.
      When trying to connect, I have an error: “Unable to enable OnCE 10-bit TAP controller Failed to connect. Could not perform custom sequence.”
      Please, tell me the reason for this error.
