Hi
I want to connect the Xc2787 chip with keil uvision5 and with ulink 2 or miniwiggler programmer but i have a problem.
this chip seems have two jtag port connection which is:
port A:
tms_a : pin39 / tdo_a: pin8 / tdi_a: pin34 / tck_a: pin 82
Port B:
tms_b: pin 118 / tdo_b: pin 121 / tdi_b: pin 117 / tck_b: 115
We connected vref and treset and ground and reset on both port a and port b but when we press the start/stop debug session, it will say that the jtag device is not connected.
I have checked the tms and tdi and tck pins via Oscilloscope and i saw that these pins have pulse except tdo pin when i start the debug session
here is the link of the chip datasheet for you:
