Other Parts Discussed in Thread: TXB0106, TXS0108E, SN74AVC4T774
Hi
I am attempting to use the TI Eye Scan GUI on custom hardware that is running the DAC39J84. I am using the same FT2232H FTDI part that is on the DAC3XJ8XEVM board and have configured it in the same way. I am able to see all JTAG signals (TCLK/TMS/TDI/TRSTB) that is output from the FT2232H, however I cannot read back on the TDO line as the TDO pin on the FT2232H appears to be configured in software as an output (or perhaps bidirectional input/output).
Is it possible for you to provide us with the LabView source .vi file, or any settings that is used in the Eye Scan GUI for configuring the FTDI part so I can try to debug what is wrong.
Thanks
