I've been trying to find a suitable ribbon cable for the 2x7 socket labeled "LTC 2x7" on the DE10 to do some hacking. I have a 2.54mm 2x7 ribbon cable but that doesn't fit. I think it must be a 2mm IDC socket.
DIGILENT sells a 2mm 2x7 IDC JTAG ribbon cable for Xylinx boards that looks correct. You can get them via eBay and Alibaba, but they have 30 day delivery times.
Has anyone found out what it is?
