  1. Testing results of PXL RDO board JTAG daisy chain Initial design Digilent USB - JTAG Fiber USB Fiber USB PC RDO board Schematic for Digilent USB-JTAG module PCB

  2. Schematic for the PXL RDO Board JTAG daisy-chain cable

  3. Initial testing with Digilent board: • This is the first opportunity to test the full compliment of 10 RDO boards. • Initial tests with the Digilent JTAG board to individual RDO boards have been and continue to be successful. • Tested at different JTAG frequencies from default (6MHz) to lowest using ISE Impact 14.5 • Tested for 4, 6, 8, 10 boards (using board bypass switches on the JTAG cable) • All tests failed – errors were • Wrong number of devices found • Devices not recognized • Only some devices recognized PXL JTAG Daisy-chain cable Digilent USB-JTAG board

  4. Since the Digilent module based design did not work for multiple boards, we tried the standard Xilinx programmer. • All RDO boards correctly recognized. • Configuration of individual boards successful in positions 5 and 10. • Flash configuration not tested. Xilinx USB-JTAG programmer

  5. Successful 10 RDO board JTAG daisy-chain using Xilinx USB programming module and PXL JTAG chain cable.
