+On Linux you may need to install docs/99-mdebug.rules in /etc/udev/rules.d

+without being root. This rules file allows group plugdev access, which
+covers users logged in on console (at least on Ubuntu)

+Connecting LPC Link 2 to debug target

-Either:
- - Install JP2 to set voltage to 3.3v and supply to VREF
- - Remove JP2 to sense voltage from VREF
+You can use the 10pin cable with the J7 connector to hook up to a target
+board that uses ARM's standard SWD debug pinout. If you want to supply
+3.3v to the target and operate at that voltage, *install* the JP2 jumper.
+If you want to operate at the board voltage sensed by the VREF pin on the
+10pin connector, *remote* the JP2 connector.
-Either:
- - Use 10 pin ARM debug cable from J7
- - Use 0.1" header J6
+You can use jumper wires from the 0.1" J6 header (see pinout below), but
+in this case there is no VREF pin available, so you must *install* the
+JP2 jumper and operate at 3.3v.
J6 Header (pin 1 is furthest from J6 silkscreen)
