Im trying to lay out a board using XU216-512-FB236 basing the design on the XP-SCK-X200 slice kit. The schematic for this board shows all of xLink 1, pins 49 through 58 going to the XLINK/DEBUG Up connector J5. There is a small adapter board that is used between Slice Kit and xTAG. The xTAG appears to only use a 2 wire connection.
So which 2 wires are used (2 up and 2 down 4 physical wires) ?
Can anyone point me to a schematic of the adaptor board XA-SK-DEBUG 1v0?
I want the final board to have a 20 pin connector we can plug an xTAG adaptor into much like the xCORE-200 MC AUDIO board.
Any pointers on the <Links> section of the SLICEKIT-X200.xn ?
My best guess so far:
Node 0 is both tiles?
Node 1 is USB?
Node 2 is xTAG?
Code: Select all
<Node Id="2" Type="device:" RoutingId="0x8000">
<Service Id="0" Proto="xscope_host_data(chanend c);">
<Chanend Identifier="c" end="3"/>
</Service>
</Node>
Code: Select all
<Link Encoding="2wire" Delays="5clk" Flags="XSCOPE">
<LinkEndpoint NodeId="0" Link="XL1"/>
<LinkEndpoint NodeId="2" Chanend="1"/>
</Link>
X1D53 = L1 0 in
X1D52 = L1 1 in
X1D54 = L1 0 out
X1D55 = L1 1 out
These map to XL1_DN0, XL1_DN1 , XL1_UP0, XL1_UP1 ? Is "in" same as "down"?
Thanks for your help!
