    JTAG CY8C3866LTI-030

    LeKu_697901

      Hello.

      The customer board includes CY8C3866LTI-030/DIE device.

      I'm trying to build Boundary Scan test for this board with JTAG Technologies Provision tool.

      The system does not recognize the device. (All ones on TDO).

      By PSoC3 programmer with MiniProg3 adapter in JTAG mode the device recognized with IR=4, DR=35. Please look attached file.

      But by the BSDL file it includes 137 bits DR.

      We have checked all lines by scope and TMS, TCK, TDI lines looks good with 1.8V level. But TDO line is no active.

      What wrong?

      Any help will be appreciable.
