Xilinx ML605 Manual page 4

Accidentally pulling on the TDO cable connected to the resistor R296 can easily tear it off and may be
difficult to repair, especially if the pad is also torn off. An improvised cable anchorage with a knot of the cable
in a hole besides the FMC LPC connector was found useful for preventing this.
Target bottom view of the board with the disabled driver U88. The orange cable at the right side of the picture
is not relevant for our purpose (zoom into the photo for details).
