+mdebug on lpclink2: Initial Installation
+----------------------------------------
+
+1. Remove jumper JP1 from lpclink2
+
+2. Connect lpclink2 to USB
+
+3. Download the "soft" bootloader via DFU
+ (it is normal to get "dfu status: io error")
+
+ $ ./bin/lpcboot dfu firmware/lpclink2-dfu.bin
+
+4. flash bootloader:
+
+ $ ./bin/lpcboot flash:boot firmware/lpclink2-boot.bin
+
+5. flash mdebug firmware:
+
+ $ ./bin/lpcboot flash firmware/lpclink2-mdebug.bin
+
+6. install jumper JP1 on lpclink2
+
+7. power cycle board (unplug/plug to usb)
+
+8. LED should blink for ~3 seconds (bootloader) then start mdebug
+
+
+mdebug on lpclink2: Upgrade mdebug firmware
+-------------------------------------------
+
+1. disconnect lpclink2 from USB
+
+2. $ ./bin/lpcboot flash firmware/lpclink2-mdebug.bin
+
+3. connect lpclink2 to USB
+
+4. If you get "flash failure", run the step #2 command again
+ (without disconnecting and reconnecting the board)
+
+
+firmware version info (debugger should show this on connect)
+------------------------------------------------------------

+
+
+connecting lpclink2 to debug target
+-----------------------------------
+
+Either:
+ - Install JP2 to set voltage to 3.3v and supply to VREF
+ - Remove JP2 to sense voltage from VREF
+
+Either:
+ - Use 10 pin ARM debug cable from J7
+ - Use 0.1" header J6
+
+
+J6 Header (pin 1 is furthest from J6 silkscreen)
